What’s been in bloom lately at the Rocky Mountain Botanic Gardens?
Tall penstemon

June 25, 2020 Jessie Berta-Thompson

The plant
Tall penstemon, Penstemon virgatus var. asa-grayi (synonym Penstemon unilateralis), Plantain family, Plantaginaceae (formerly Figwort family, Scrophulariaceae)

There’s been a surprise growing at the gardens in the past few weeks. What started out as few notes of lilac color in the meadow-like area at the back of the garden grew to an orchestral swell of penstemon flower spikes. Last year, our gardeners worked in this part of the garden to remove the most serious weeds
and cut back overgrown material, but otherwise the land was left to its own devices. Delighted by this plant’s unexpected abundance, a few of us spent some time with magnifying glasses and books to figure out what it was. To the best of our abilities, we came up with this stunner most likely being tall penstemon (Penstemon virgatus var. asa-grayi as well as the synonym Penstemon unilateralis). This plant is also called upland blue beardtongue, upright blue beardtongue, wandbloom penstemon, one-sided penstemon, and beardless sidebells penstemon. Where did it come from? We didn’t plant it, but it could easily have hopped the highway or river from a population in the foothills, or perhaps past human wildflower lovers helped it move into town. This plant is common up and down the Front Range. Its distribution map cuts a wide north-south path through the middle of the state, growing in grassy habitats, on rocky hills, and, father south, among the pinyon-juniper forests. This plant also grows in Wyoming and New Mexico.


Tall penstemon blossoms are various shades of light purple, with delicate lines marking the way to the paler interior. Like many penstemon species, the flower color varies quite a bit from plant to plant, pinker to bluer and darker to lighter. The flowers are shaped like bells or tubes, splitting into 5 petal lobes, with two lobes at the top and three at the bottom. Its pollen is borne on 4 stamens that curve around the inside of the blossom like a ribcage, and there’s a fifth sterile stamen called a staminode (characteristic of penstemons), which can be seen running up the base of the flower tube. Larger pollinators that make it into the flower for nectar get an automatic dose of pollen from the stamens curving over the flower entrance, acting like spring-loaded back-scratchers. As its name suggests, this plant is tall for a penstemon, typically growing to 20-60 centimeters or sometimes as high as 1 meter. Penstemon seeds are produced in capsules that split open when ripe, revealing little cups full of small, irregular seeds.

Telling this plant apart from its relatives came down to size (big), how the flowers all point in about the same direction, the absence of hairs (many other penstemons have small hairs on the flowers, leaves, or stems), the shape of the anthers (the pollen-holding structures, which are in pairs opposite each other), and the shape and color of the leaves (narrow, green). For example, in the plains and foothills around Lyons, another very similar penstemon is commonly seen. Called the one-sided (again) or sidebells penstemon (Penstemon secundiflorus), this plant also has one-sided flower spikes, with an overlapping color spectrum of pale pink to purple flowers. However, it has a fuzzy yellow staminode - the bearded tongue that gives the penstemons their name beardtongues - while the tall penstemon has a plain white hairless staminode, a difference visible with a quick peek into a flower. The one-sided penstemon’s leaves are also paler, wider and juicier. Both are very nice to come across, regardless of identification.


As it turns out, there are a lot of different kinds of penstemons. In Colorado alone, there are about 56 penstemon species of growing wild, based on the species described in the comprehensive 2015 book, ‘Flora of Colorado’ by Jennifer Ackerfield. Of these, 9 species are endemic to Colorado, meaning they are native to and found only in the state. To preserve this remarkable diversity in the face of habitat loss, two of these endemic penstemons are on the Federal Endangered Species list (Penland’s penstemon, Penstemon penlandii, listed as endangered and Parachute penstemon, Penstemon debilis listed as threatened). The designs for planting in the botanical gardens include 7 of the more common penstemons. The tall penstemon that we already know likes growing on the RMBG plot will be intentionally planted in the labeled beds, along with the low or bluemist penstemon (P. virens), one-sided penstemon (P. secundiflorus), dusky penstemon (P. whippleanus), Palmer’s penstemon (P. palmeri), firecracker penstemon (P. eatonii), and Rocky Mountain penstemon (P. strictus). Together, they should display a good range of the variety found in the world of penstemons.

Penstemons are in the Plaintain family (Plantaginaceae), named for the European medicinal plant that’s now a common North American weed. This family includes foxgloves, veronicas, and the high elevation tundra plant alpine kittentails (Besseya alpina). However, for many years, penstemons were classified in the Figwort family, Scrophulariaceae, as older field guides will attest. The re-assortment of Figwort family members came about when DNA sequencing began to help evolutionary biologists untangle the relationships between species in a more direct way than older methods, which were based largely on flower details and other mostly visual features of plants.


Penstemons are widely enjoyed, as wildflowers encountered on hikes and as gorgeous, pollinator-sustaining garden plants. Many varieties are available for planting, both native species and cultivars bred to new combinations of size and color. Purple, white, and blue penstemons, including the tall penstemon, are
primarily (but not exclusively) pollinated by bees and a specialized pollen wasp, Pseudomasaris vespoides. This wasp visits many penstemons, including rare and endangered ones that really need their pollinators, and it rarely stings, although it bears a menacing resemblance to yellow jackets. The purple-white-blue penstemons generally have flowers that are sturdy and fixed horizontally to support the weight of these insects while they work. Red, orange, and pink penstemons are more adapted for pollination by hummingbirds, though insects visit them, too. In addition to the color, some red-orange-pink penstemons have evolved downward facing, narrower, longer tubes that hummingbirds can comfortably hover below.

In other, very important, RMBG news, a 400-foot irrigation tube has been installed, and planting has begun! The first planting day was Tuesday, June 23, when volunteers worked to tuck many flowers, grasses, and shrubs into the Prairie Grasslands Garden. The plants are here! And for a bit more about Tall Penstemon take a look here: http://beta.floranorthamerica.org/Penstemon_virgatus_var._asa-grayi






What’s in bloom this week at the Rocky Mountain Botanic Gardens?

Black locust

 

6/11/2020 Jessie Berta-Thompson, photos by Zach Berta-Thompson

 

Plant in bloom:

Black locust, Robinia pseudoacacia, Legume family, Fabaceae

 

High above the beds of the RMBG, several of the old trees that were glumly leafless all spring have finally sent out their leaves and, what’s more, exploded into bloom. These trees are black locusts, currently festooned with large, drooping clusters of fragrant flowers.


Black locust flowers are white, occasionally tinged with pink, with a small streak of yellow up close. The tree has compound leaves, meaning each leaf is made up of multiple leaflets attached to a single leaf stem, in this case, 7-21 thin oval leaflets branching off to feathery effect. The black locust’s species name pseudoacacia and another of its common names, false acacia, refer to the similarity of its leaves to those of the acacia tree. On new shoots and twigs, a pair of short, stout thorns appear at the base of each compound leaf. The mature bark forms deep furrows and ridges that separate and rejoin as they wind up the trunk, giving it a woven or knitted look. Flat, brown pods from last year, 2-6 inches longs, are visible on the branches, and dark seeds, like little beans, still cling to some. 




Black locusts can also spread by sending up new growth from roots to form clonal thickets. Black locusts are fast growing and relatively short-lived trees, typically lasting around 60 years and occasionally living up to 100 years. The flowers produce abundant nectar beloved by pollinators, and, by extension, beekeepers, who particularly value the delicate flavor of black locust honey (sold as acacia honey in some places).

 

There are a few other kinds of locusts planted along the Front Range that occasionally escape their gardens. The New Mexico locust, Robinia neomexicana, is native to the Southwest (southern Colorado, but not here), has pink flowers, hairy seed pods, and grows more as a shrub than a tree. The honey locust, Gleditsia triacanthos, has yellow-green flowers, smaller leaflets, an even number of leaflets on each leaf compared to black locust’s odd number, larger seed pods, and branching thorns. The Bristly locust, Robinia hispida, can be differentiated by its pink flowers and very hairy stems.

 

Locust trees are in the legume or pea family (Fabaceae), and so are peas, beans, acacias, lupines, and wisteria, with its similar drooping flower clusters. Another legume family member, purple prairie clover, Dalea purpurea, is slated for planting in our Prairie Grasslands garden soon. This family is known for its symbiosis with nitrogen-fixing bacteria. These bacteria live in specialized nodules on the roots of legumes and perform a powerful and costly chemical reaction to turn inert nitrogen gas from the air (which is made up of 78% nitrogen gas) into ammonia, a form of nitrogen that plants can use. The bacteria are fed with plant sugars, the plant receives a key nutrient, and the process adds more total bioavailable nitrogen to the ecosystem, enriching the soil and helping other plants.



Black locusts originally come from the central Appalachian Mountains and the Ozarks, evolving on lush mountainsides. They are useful, beautiful, and adaptable trees and so have been widely planted all over the country and the world for centuries. The genus name, Robinia, refers to Jean and Vespasien Robin, a father-son team of botanist-gardener-herbalists credited with planting the first black locusts in France in the 17th century. Black locusts are planted for apiculture, for their wood, as ornamentals, to provide quick-growing shade, and for erosion control. Two major pests, the locust borer and locust leaf miner, sometimes work against these goals.

 

In many places, the black locust has escaped cultivation. In Colorado, it is spreading out around old farms and towns and creeping up riparian corridors and ditches. It can cause problems by crowding out other plants, sucking up limited water resources, forming hard-to-remove dense thorny thickets, poisoning livestock (it can make a toxin related to ricin), and facilitating co-invasion by noxious weeds that ride its nitrogen wave into new habitats. However, the same traits that make it a weed in some contexts – fast-growing and tolerant of lousy conditions – also make it a valued restoration plant, used for reclamation of heavily damaged mining sites.

 

Among the reasons people have planted the black locust so widely is its close-grained wood, which is hard, dense, and strong. The tree is sometimes called the post locust, because the wood is so useful for fence posts, durable and resisting rot in soil contact. It’s been used for tool handles, furniture, ships, mine timbers, and railroad ties. I didn’t expect my reading on the flower that caught my eye this week to come up with anything like this, but, because of its hardness, black locust wood was also used for making police batons in the late 19th century. Known as locust clubs, at the time they caused terror and controversy about the nature of tools and tactics used by police, so sadly resonant with today.


 

To see this species and reflect on its history, the black locust trees at the RMBG are visible from the river path between Bohn Park and the Labyrinth by Route 7. An evening stroll is best to appreciate the scent. They are some of the tallest trees in the garden, with some bare, dead branches, likely indicating senescence or disease. It’s also worth finding a shorter tree to enjoy the flowers and insect activity at eye level. There are many black locusts, of all ages and growth forms, up and down the St. Vrain.

 

A particularly stunning specimen can be seen behind a dumpster on Park Dr. near the Lyons Town Hall. This tree is the representative for its species in the Lyons Walking Arboretum, a collection of trees with identifying signs paired with a walking tour map and illustrated guide. The Lyons Walking Arboretum was created as a joint project of the Town of Lyons Ecology Advisory Board and the RMBG, transforming trees already present in town into a toolkit for botanical education and appreciation. Get the map and guide (link below) and take a stroll, mindful of the trees that have been planted in Lyons over the years.

What’s in bloom this week at the Rocky Mountain Botanic Gardens?

White Campion

 

6/1/2020 Jessie Berta-Thompson & the RMBG

 

Plant in bloom:

White Campion, Silene latifolia, Pink family, Carophyllaceae

 

The bright bulbous blossoms of white campion have popped out this week, along the river trail and behind the garden compost pile (which is getting very large from all the weeding that’s been going on lately). The most distinctive part of a white campion flower is the calyx behind the petals, which inflates balloon-like around the developing seed capsule and is decorated with green or purple-red veins. A calyx (plural, calyces) is the structure that protects a flower bud. After a flower opens, the calyx on many species looks like a set of small petal-like leaves or leaf-like petals (known as sepals) at the base of a flower, but the calyx of white campion is prominent and fused into one piece. Each flower also has five white petals with deep notches nearly splitting them in half, and there’s a little extra frill of a collar at the flower’s center. The plants are hairy, which makes new leaves soft to the touch and the calyces, already striking at a distance, look even wilder under a magnifying lens. This plant is a Eurasian native, introduced and now widespread across North America. In typical weedy fashion, it grows on roadsides, floodplains, disturbed areas, meadows, and cultivated land.


In the heat of midday, white campion often looks crumpled. That’s because these flowers bloom at night to attract moths as pollinators. They also release their fragrance at night. Certain other white flowers do this, too, so gardeners sometimes plant collections of fragrant white night-blooming flowers to enjoy after dark. The RMBG Prairie Grasslands garden (slated to be planted first) will include two species of native evening primroses, the prairie evening primrose, Oenothera albicaulis, and the white stemless evening primrose, Oenothera caespitosa. Like white campion, these flowers open in the evening, as their names suggest. Both grow low to the ground with stunning, large white flowers pollinated by night-flying insects.

 


Up close, white campion flowers don’t all look the same. This species is dioecious – each plant has either male or female flowers. This is one of the mechanisms plants have evolved to avoid self-fertilization and excessive inbreeding, increasing the flow of genetic material by requiring two parent plants for every seed. The flowers on male plants have bright clumps of yellow pollen at the center, while female flowers have a cluster of curving white structures to catch the pollen. Only the fruit-bearing female flowers have the ballooning calyces. On males they are still noticeable but don’t puff up. Another dioecious species among local favorites is the rocky mountain juniper (Juniperus scopulorum). Some plants bear juniper berries while others produce pollen-spewing male cones that give the plants a brownish-yellow look in spring.

 


White campion is in the Pink family (Caryophyllaceae), named for the flowers called pinks, which are also known as dianthus and often are actually pink. Carnations and sweet Williams are other cultivated members of this family. Colorado native Pink family species include the prairie mouse-ear, Cerastium arvense, which forms constellations of white flowers under ponderosas in spring, and the pink cushion-forming alpine favorite, moss campion, Silene acaulis. At first glance, two other Pink family members introduced from Europe can look like white campion. Bladder campion, Silene vulgaris, has even larger bladders (calyces) that lack the dramatic veins of white campion, and bouncingbet or soapwort, Saponaria officinalis, has petals without the deep notch, a slender calyx, and hairless leaves. Bouncingbet and white campion were both used historically as soap, their roots beaten to a lather for laundry. Keep an eye out for white campion blooming around town all summer long – it’s certainly a plant worth a closer look, but don’t expect to see it (much) in our lovingly weeded native garden beds.


 

In other garden news this week, our partners at the Town of Lyons have just completed the work for the garden to get irrigation water. Although we’re planning to use as little water as possible, watering will be necessary for establishing young plants. This brings us one step closer to planting!

Chokecherry

 

May 25, 2020 Jessie Berta-Thompson & the RMBG

 

Plant in bloom:

Chokecherry, Prunus virginiana var. melanocarpa, Rose family, Rosaceae

 

Throughout the month of May, Lyons has been full of flowering chokecherries (Prunus virginiana var. melanocarpa). The chokecherry is related to the cherry, and the choke part is about the bitterness of the fruits. It’s also called wild cherry, bird cherry, and chuckleyplum. This lovely shrub is recognizable by its elongated, drooping white flower clusters. Flowers are set against bright green leaves, which have tiny teeth along their edges and are widest slightly above the middle of the leaf, useful for telling it apart from other local cherry relatives, wild plum (Prunus americana) and pin cherry (Prunus pensylvanica), when there aren’t fruits and flowers around. The bark on young branches is dark with pale spots called lenticels, which are pores that allow gas exchange through bark. In Colorado, chokecherries usually grow into shrubby thickets, but in rich, wet conditions they can become small trees. The blossoms are starting to fade in Lyons, but they can still be spotted at higher elevations through June.

 


The sweet-scented flowers of the chokecherry are a great, abundant early resource for bees and other pollinators. Soon, clusters of little round fruits will start to ripen, going from green, to red, to black. Chokecherries are beloved by birds, bears, and many other animals, who eat the fruits then disperse their seeds far and wide. People eat them, too, sweetened in jams, in sour craft beers, or straight off the bush, avoiding the toxic pit. Indigenous tribes developed many culinary preparations for chokecherries, including some that neutralized the seed’s toxins, and used many parts of the plant for medicine and dyes. The fruits make a purple-red dye, and the inner bark and leaves make green.

 

The chokecherry is a stone fruit, forming a group of close relatives along with cherry, peach, plum, and apricot, all sharing hard pits and attractive spring blossoms. In addition to the chokecherry, we’re looking forward to planting two other stone fruits native to Colorado in the RMBG, the sand cherry (Prunus pumila var. besseyi) and the wild plum (Prunus americana). These plants are all in the diverse Rose family (Rosaceae), which includes roses, raspberries, and the native shrubs bitterbrush (Purshia tridentata) and mountain mahogany (Cercocarpus montanus).


 

The chokecherry is found throughout North America, but our local variety, with deep black berries, is native to the West. It grows in gulches, along hillsides, and especially near streams and rivers. Its bigger, greener leaves stand out among foothills shrubs, and they turn yellow in fall. Along the St. Vrain, chokecherries have been included in flood restoration plantings, a healthy part of a riparian ecosystem, controlling erosion and feeding wildlife.  At the RMBG, there are mature chokecherries growing around the margins and little clumps shooting up in the beds, all on their own. They didn’t self-plant exactly where we wanted them, so we’ll have to plant a few more in the Riparian garden, where we’ll be showing off the lusher side of Colorado plant life.

Blue mustard

 

5/20/2020 Jessie Berta-Thompson & the RMBG

 

Plant in bloom:

Blue mustard, Chorispora tenella, Mustard family, Brassicaceae

 

After years of work by our passionate plant lovers to create a native plant garden in Lyons, the RMBG is a maze of gravel paths and tidy mulch, almost ready for planting! Right now, the garden is closed to let worms, fungi, arthropods, and microbes build up the soil undisturbed. These critters are busily composting the cardboard and wood chips covering the surface of the beds to make rich soil. Meanwhile, human volunteers are pulling weeds and continuing soil preparation. The planting and the opening of the gardens are expected midsummer. When that happens, we’ll use this space to share what’s going on at the gardens, botanically speaking, and to share our love of local plants.

 

Since there’s nothing officially planted in the gardens yet, it’s a bit early to be talking about what’s blooming there, but there are actually lots of flowers – on the weeds.  In the RMBG and all over Lyons, the rather lovely and tenacious weed known as blue mustard (Chorispora tenella) is currently in full bloom.



Also known as crossflower, musk mustard, or purple mustard, this plant has pale purple, slightly wrinkly, 4-petalled, x-shaped flowers, and the leaves have a distinctive odor. It’s an annual plant that forms upward curving pods, plump with next year’s weed seeds. Up close, the leaves, stems, and pods have tiny hairs. This plant is an introduced species, native to Eurasia but now found in many Western and Midwestern states. It can form dense carpets of purple haze along roadsides.


Blue mustard is a member of the mustard family (Brassicaceae), which includes the spice in the yellow bottle, cruciferous veggies like broccoli, kale, and Brussels sprouts, and many native wildflowers, including Western wallflower (Erysimum capitatum) and Front Range twinpod (Physaria bellii). Blue mustard is just one of many early-blooming mustard family weeds that infest and/or grace local disturbed areas in spring.

 

Keep an eye out for blue mustard around town and in your yards, enjoy the early color it brings, then consider pulling it up to make more room for our native plants. We’ll keep weeding at RMBG to get ready for the many flowers to come.

December 2018

posted Dec 19, 2018, 1:42 PM by Deirdre Daly

Garima Fairfax, president of the board of directors, presented to the Town of Lyons Board of Trustees at their December 17, 2018 meeting. Garima was accompanied by members of the Rocky Mountain Botanic Gardens (RMBG) board and other supporters of the Botanic Gardens. The Trustees indicated their approval of the project and directed the RMBG board to complete the application for license to use the property for the Gardens. A copy of Garima's presentation is attached here for anyone who may be interested.

The next step is to begin to weed the property in preparation for the Gardens. If you're able to help, we'd love to have you! Please contact Garima at garima@rmbg.org or complete the form on the About Us/Contact Us page.

Spring 2018 update!

posted Apr 27, 2018, 5:02 PM by Toshen

As the Town of Lyons continues to recover from the 2013 flood, a number of properties have become available through the Dr. BOP (Deed-Restricted Buy-Out Properties) program. The Rocky Mountain Botanic Gardens group was asked by the town staff to choose which parcel would best fit our purpose, and to then give a presentation to the Town Board of Trustees.

We chose the lot in the confluence that used to be the mobile home park, near the corner of 4th Ave and Prospect St. We presented our proposal, found everyone in favor, and are now drawing up our budget and timeline. When the town approves that, we then ask for approval from FEMA.

We are very excited about this location for the future botanic gardens of Lyons, the very first in Boulder County. It is 1.26 acres adjacent to both the South St. Vrain River and the nearly completed Bohn Park, and is walking distance from downtown Lyons. The nearby neighbors we've spoken with are very happy with our plans.

The members of our volunteer group are Anthea Rice, Kris Todd, Garima Fairfax, Dianne Andrews, Carter Christenson, and Deirdre Daly. We also have 25 volunteers who are enthusiastic to help build the display gardens. If you'd like to be added to our email list of volunteers, please contact Garima: garima@rmbg.org

We plan to begin on the lower part of the parcel, and to divide this area into the natural ecosystems of Colorado: foothills, prairie grassland, montane, riparian (plants that grow along rivers), and plants that grow in the southwest part of Colorado. We'll have pathways meandering through the display gardens, and visitors can learn the names of local plants they see while out hiking, or find new local plants they would like to have in their gardens. Native plants do well in a garden situation, and need less water and fertilizer than cultivated plants. 

The garden will also be a place to view native birds and butterflies from a bench along the path, or to come and do watercolor paintings of native flowers. Our annual plant sale every May supports the creation of this educational garden. 

See the Our gardens page for an updated drawing of the gardens.

Not Now, Deer

posted Jan 13, 2013, 11:09 AM by Garima Fairfax   [ updated Dec 12, 2018, 11:34 AM by Deirdre Daly ]

by Garima Fairfax 

I just found a book called DEERPROOFING YOUR YARD & GARDEN by Rhonda Massingham Hart. It starts with eye-opening facts about deer that help you understand their perspective, as well as their strengths and their beauty, and their incredible senses of smell, hearing, sight, and survival.

You can read about every type of deer deterrent, from fencing to rattling scarecrows to foul smelling rotten egg sprays (homemade or store bought), complete with all the pros and cons of each. As an example, you might have heard that scented bars of soap hanging from trees can deter deer from feasting on tasty garden flowers and greens. But did you know that it takes 450 bars of soap per acre to be effective? And that these same bars of soap can actually attract rodents?

Well, maybe after reading all of that, you want to try planting known deer-resistant plants. Here are a few that I have personal experience with that do well in and around Lyons, Colorado. (The book includes every area of the country.) If your garden is near a natural area, be especially careful to plant only native plants, OR if you plant non-native plants, chose only non-invasive species.

The Common Juniper

posted Jan 13, 2013, 10:42 AM by Garima Fairfax   [ updated Jan 13, 2013, 10:45 AM ]

We have in our woods here in Colorado a prostrate juniper called Common Juniper (Juniperus communis subsp. alpina). Less than 3 feet high, it forms a low, spreading clump. You’ve probably seen this coniferous undershrub in our forests, but you may not be aware of how common it really is. It turns out that it is the most widely distributed conifer in the world, and the only circumpolar conifer in the northern hemisphere. That’s enough to warrant a closer look.

This Common Juniper is an evergreen shrub with short, sharp needles, with female or male cones generally on separate plants. The female cone scales are fused together to look like round berries, green at first, then ripening to a dark blue with a grayish “bloom” or coating. The male cones are very small, and can be found at the tips of the branches while they form pollen. After they release their pollen, they disintegrate.

The female berries are an important source of food for birds and small mammals in our woods, and have a long history of medicinal use by Native Americans coast to coast, Europeans, and Northern Asians. This low, spreading juniper, which is found sprawling under Ponderosa Pines of the foothills and all the way up to Bristlecone Pines in the subalpine, proves itself to be a valuable and adaptable member of our ecosystem.
