Discussion

Variety flavum is widespread and rather common on the short-grass prairies of the Great Plains from Alberta, southwestern Manitoba, and Saskatchewan south through North Dakota, South Dakota, Nebraska, and eastern Colorado, westward across the plains and into the mountains of Montana and Wyoming. It occasionally is cultivated and, while slow-growing, it will, given time, form nice mats, with a fair profusion of inflorescences bearing bright yellow flowers.
