To quote the Alplains seed catalog from whence this came:

(W) Carbon Co., UT, 5700ft, 1738m. Absolutely the best and most colorful form I have seen -- dozens of scapes (I counted 60 to 80 on the largest plants) with huge poms over an inch wide form a dense canopy over the gray cushions. Flowers are multicolored yellow, red, pink and/or cream, Photo by Alplains
