Germination for this species is different from some of the other arabis species that will germinate in 20 - 25 days after being sown around 70*F.

For Arabis lyrata, "Sow at -4*C - +4*C (24-39*F) for 12 weeks, and then move to 20*C (68*F) for germination"

This wildflower is native at least in Connecticut, prefers rocks & sandy soil and is host for larva of falcate orange-tip butterfly
