The Casper Star Tribune (Wyoming's statewide newspaper) article, "Hike takes people to state’s only endangered plant," published today, discusses penstemons and the upcoming American Penstemon Society/Wyoming Native Plant Society meeting in Laramie on June 22-25.  The endangered plant the article refers to is the Blowout Penstemon (Penstemon haydenii, shown right), found only in active sand dunes like those in central Wyoming.  

Read the article!

Our very own Dorothy Tuthill is quoted in the article,  as she happens to be an expert on penstemons, particularly those found in Wyoming.  You may have read about the variety of penstemons we feature in the Berry Prairie.  The species found in Wyoming are extremely drought tolerant plants, and in fact prefer very little water over regular watering.  In a recent presentation to the Laramie Garden Club Dorothy noted some species' "flowers are even more vibrantly colored when they're drought stressed than when they're well watered."  

Below are photos of the two penstemons in bloom in the Berry Prairie, the Fuzzytongue (P. eriantherus) and Blue Mist (P. virens) penstemons. 

The Berry Center is also installing a penstemon garden this summer to showcase the impressive diversity within one genus, so stay tuned for more updates!

Memorial Bloomers

The Berry Prairie is alive with blooming plants.  They're a variety of colors too - purple, yellow, white, blue, red.  The red, white and blue ones I'm sure are feeling very patriotic - but the others are looking very stately as well.  Take a gander!

Red

Prairie Smoke (Geum triflorum)

This little gem was one of the first to bloom on the prairie, and is still going strong.  None of the flowers have turned to the wispy tentacles of the seed-head yet, but a few are getting close.

White

Hooker's Sandwort (Eremogone hookeri)

This plant is new to the blooming game, and isn't it great!  This plant sits about 2-3 inches tall and measures about 3 inches across, so it's a pretty understated and awesome.

Fleabane (Erigeron compositus)

This fleabane is one of four fleabanes on the green roof - another one, the desert yellow fleabane is also in bloom, and we'll feature that soon.  It has a Medusa-like flowering style, with flowerheads sticking up all over.  Dorothy wrote about this plant a few weeks back.

Dwarf Pussytoes (Antennaria parvifolia)

Who doesn't love these groundcovers?  The dwarf pussytoes flowers are shown below, in their nodding fashion.

Locoweed (Oxytropis nana)

The locoweed is a very common road-side plant around Laramie and can either be white or purple. 

Laramie Columbine (Aquilegia laramiensis)

Isn't this one a peach?  Dorothy featured this plant in a post a couple weeks ago - check it out!

Blue

Colorado Blue Columbine (Aquilegia caerulea)

The beautiful Colorado Blue Columbine is now blooming on the Berry Prairie, and its tall, striking flower stalks are hard to miss. 

Blue Flag (Iris missouriensis)

These iris are typically a water-loving species, but these plants seem to do ok on the relatively dry green roof!

Blue Flax (Linum lewisii)

Blue flax is blooming all over town and is beginning to do its thing on the green roof.

Blue Mist Penstemon (Penstemon virens)

The electrifying blue of these great forbs are outstanding, and quite common around campus.  Notice that you'll find most of the blooming specimens on campus nestled in a boulder, which speaks to its preference for ultra-dry environments.

There are more species blooming on the green roof!  Stop by to check them all out!

Laramie Columbine: Gem of the Gem City

Laramie columbine is the most recently blooming species on the Berry Prairie!

Laramie columbine - now blooming on the Berry Prairie - is a petite gem, whose native distribution is restricted to the Laramie Range of Albany and Converse counties. Aquilegia laramiensis was first collected by Aven Nelson in 1895 in the northern part of the Range, and a few years later much farther to the south, not too far from Laramie. Seventy years passed before botanists once again took up the search, relocating the original sites, and filling in some gaps. 

Yet, Laramie columbine remains rare and elusive. Restricted to granite outcrops (like below), it hides in crevices and beneath ledges, lurking in cool and shaded microsites, usually far from well-travelled paths. As of 2012, it was known from 49 sites, most with fewer than 100 plants, but, due to the ruggedness of the area, but it is difficult to get complete counts across rocky outcrops.

Both the Forest Service and the Bureau of Land Management have designated Laramie columbine as a sensitive species, meaning that they attempt to manage land in a way that protects the species. Because of its remote and rugged habitat, the populations are not generally threatened by changes in land use. 

Perhaps the biggest threat to this gem is its desirability to gardeners, who may remove specimens for personal use. Because of the small numbers of individuals in some populations, the removal of even a few plants is potentially devastating to the entire population. Fortunately, plants are sometimes available for purchase through commercial growers, or, you can do like we did, and buy seeds to grow this lovely little columbine yourself.

Wildflower Field Guides: Tried and True

With more plant species coming into bloom every day (well, maybe not today, with our fresh snow), it’s time to dust off the field guides. There are lots of newer books available for wildflower identification, but here are a few suggestions from the tried-and-true category.

For the Hard-Core Plant People:

For serious wild flower enthusiasts, the only all-inclusive book about Wyoming vascular plants (no mosses or liverworts) is Vascular Plants of Wyoming, by Robert Dorn (third edition, 2001). Keys are provided to every taxon in the state, along with indications of where in the state each is found. The glossary at the back of the book will help with the vocabulary, but there are very few pictures to let you know if you’re getting close. To see many of the traits used in the keys, you’ll need a hand lens or a microscope.

For the Aesthetically-Minded Plant People:

If getting a species name is not a necessity for you, Diantha and Jack States’ book, Wildflowers of Wyoming (2004), will get you quickly to the correct family or genus. A key to families is provided, as are pictorial guides to plants based on flower color and shape. Many common species are included, with great photos (and common names!), and mention is made of similar species.  

For History-Buff Plant People:

Another book to consider is Ruth Ashton Nelson’s Handbook of Rocky Mountain Plants (fourth edition, 1992). The newest edition is called A Guide to Rocky Mountain Plants, by Roger L. Williams (2002), who revised the previous edition of Nelson’s book. Nelson was the wife of Aven Nelson, Wyoming’s first botanist, UW’s first faculty member, and president of UW from 1918 to 1922, so using her book puts you in a direct lineage with a very well-known botanist! When you tire of identifying plants (as if that ever happens!) you might want to pick up Aven Nelson of Wyoming, also by Roger L. Williams (1995).

For High Altitude Plant People:

Another lovely picture book, useful for plant identification when you travel to the high country, is Alpine Wildflowers (Dee Stickler, 1990). It’s also useful for making you wish you were traveling to the high country when you’re not, or that it could be summer, when it’s still winter.

For Low Altitude Plant People:

And if you’re in the low country, consider Weeds of the West (Tom D. Whitson and others, 9^th edition, 2006). In this case, “weed” means a plant that “interferes with management objectives.” While many of these plants are weeds by any definition, some are quite lovely native wildflowers that happen to be successful in disturbed and dry habitats.
