|Paeonia hybrid, tree peony|
Although classified as a woody shrub, it typically suffers severe die-back every winter (in my garden) then bounces back to form a 3'x3' shrub with these beautiful, 6-7" diameter blossoms. This is one plant in my garden that I'm willing to provide with a bit of extra water. Every garden needs one or two exotic specimens, right? A gift from a gardening friend many years ago, I'm sorry that I can't recall the specific variety.
Update: After doing some research, I believe that this is Paeonia suffruticosa 'Kinkaku' or 'Souvenir de Maxime Cornu'
May is also prime time for Iris germanica, bearded iris. There are two fantastic iris farms in the region where you can see scores of varieties in bloom and place your orders directly with the grower for post flowering delivery. Iris 4 U is in the Englewood area, and Long's Gardens is in central Boulder. Always a fun outing and it's nice to support our local farmers, too. But don't delay, the gardens are only open for a few weeks during the peak blooming season.
|White iris & white flowering Cerastium tomentosum make an elegant and xeric combination.|
|Love the hidden "zebra" stripes here!|
|A great, water-wise butterfly plant. Deadhead for repeat blooms all summer.|
An underused perennial that is also quite drought tolerant is this sweet Verbascum hybrid. It stands about 20-24" tall and blooms for several weeks.

Our native spiderwort, Tradescantia occidentalis, adds a col hit of blue and is happy to reseed itself in the driest garden areas.
|This linear, horizontal foliage is a favorite of mine.|
