Seed ripensextended period, starting early July

The tallest of the cranesbills in our garden, growing to a large, billowing mound, with lots of black-eyed purple flowers late spring into summer. It happily accepts its position in full sun and occasional drought, which has earned our original plant and several of its offspring prominent positions in our front lane.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
