Eremurus himalaicus and unidentified giant allium.
If you haven't been, or if it's been more than a year, I highly recommend a visit. Every garden is a constant work-in-progress and, though I always thought the DBG was a sad reflection of Denver, the garden's really hit it's stride. Except for the missing (temporarily, I hope) orchid room, the recent renovations have made it a real joy to visit again. The new parking structure across the street is, itself, worth the price of admission. Go now, before the summer heat and drought frizzles everything.
Oh, and Thanks, Mom for the Entertainment Book. BOGO coupon got us both in for $12.50!
