Tulips in August (gentians that is…)

Tulip gentian (Eustoma grandiflorum) on Ft. Collins open space land

Everyone flocks to the mountains in August (I can hardly blame them: the mountains are dazzling this year) but one of Colorado’s choicest wildflowers is blooming now, in August right down here on the Plains. The Tulip Gentian is now a popular cut flower and occasionally even sold as a bedding annual. I have stumbled upon colones a half dozen times in my life. Most of these have subsequently been strip mined for gravel, or in the case of the last colony in Metro Denver, a strip mall was put over its habitat. Not to depress you, my friend, but we are paving paradise and putting up parking lots!

I first discovered a vast colony of tulip gentians that seemed to be secure: they are growing on land that had been already mined for gravel. Twenty or more years ago when I first found them there were thousands in all colors of the lavender spectrum from pure white to deep violet purple. Last week we found a half dozen plants instead of the accustomed throng. Maybe they will be back next year. Nature is never static. It is worth every effort to find this increasingly scarce plant. Few habitats in Colorado have been altered more (in bad ways!) as much as lowland riparian habitat where this was once abundant.

Finding one of my favorite butterfly weeds growing nearby was a terrific bonus: what a fabulous range of colors in one plant! I have seen this in the Midwest and East Coast. Funny that this grows in swamps, while at DBG this takes even some rather xeric spots.

Of course, the reason for going to Ft. Collins was to see the incredible Annual Displays on Remington St. across from the College: the display this year was especially striking. These two gentlemen are the ones responsible for Colorado’s looming presence in the realm of annual plants. Al has helped Jim develop one of the most ambitious–and beautiful–of test gardens. The visitation there is tremendous, and most industry people who come anywhere near Colorado make a point of checking out the trials. You should too (they are open and free to the public). With rare plants nearby, some of Colorado’s best Garden Centers, and Wyoming a mere skip and a hop behind, I suspect that many local gardeners will find themselves (like me) making frequent treks to “The Fort”. I recommend you do so at the soonest opportunity!
