On a recent trip to Denver, Colorado to visit my husband's brother and family, we took a trip to the Denver Botanic Garden. I encountered some incredible plants, many for the first time, thriving in a climate unlike any I have ever gardened in before. In some respects the desert and high altitude region seems harsh, but then again, many plants that have trouble over wintering in Vermont, seem to do just fine here. It was amazing to see what plants were entirely happy with extreme temperature changes coupled with constant dryness and drought. All those beautiful silvery leaved plants, gorgeous grasses, and unusual succulents were in their ultimate growing conditions.

I liked this little tableau of interesting foliage, shapes, textures and colors. I think the emerging purple flowers belong to Crocus speciousus, but I am not entirely confident in my ability to appropriately identify the crocus/colchicum bulbs. My inexpert guess is based on the great photographs and descriptions of the various autumn flowering bulbs found in a a recently acquired copy of Anna Pavrod's book titled Bulb.
Bouteloua graculis 'Blonde Ambition'
This was one of the most exciting plants I saw and it caught my eye from a great distance. This grass is truly blonde with dainty, angled seed heads flicking about in the breeze. It is short (about 30"), but dense and extremly upright. Apparently the seed heads can stand tall through the winter. It is also cold hardy to Zone 4.
Erigonum wrightii var. wrightii (Snow mesa buckwheat)
I recently read about these great buckwheat plants perfectly suited to mountain climates and a great food source for the pollinators. Its seed heads are extremly beautiful, emanating a lovely coppery glow.
A bamboo sculpture exhibit was going on in different parts of the garden and here the pool was decorated with these wiry objects rising up from the inky black water.
I thought this was another man made sculpture, but these wide, flat pads are in fact living waterlilies. Victoria 'Longwood Hybrids'
The native plants garden was perhaps my favorite part. Since I arrived in this arid city, I have been enamored with all the wild plants that grow here- from peoples' cultivated gardens to the weeds in the sidewalk. The large shrubs with a blush of pink are Artemesia tridentata, which are seen everywhere.
