A leafy central stalk is typical for this plant.
It's not unusual for each plant to bear just a single flower . The Draba cuneifolia in the lower center, a tiny plant in its own right, dwarfs the even tinier Draba reptans. These two species are often found growing in the same site.
Draba reptans is currently at the tiny rosette stage, but will be blooming within the next couple of weeks. Watch for it in open rocky sites in Southern Ohio.
