This is a rock garden plant, well worth growing if you have a gritty bed with perfect drainage in full sun.

Easier in western N. America than in the east. Does well in slightly alkaline soils, but does not require them.

Hardy in Z4/5 to Z7 in the east. Does not tolerate the hot humid summers of the southeastern US. May be fall planted in hot summer climates for spring bloom, then discarded like an annual.

Short-lived, may self-sow where happy.
