This is a loooooong bloomer! It's been blooming from May to July and only now, middle of July, are the flowers going to seed. It's lovely as an edging along my patio steps and also seeded itself into my herb basket. In another location, I have it as a single accent plant.
On the tag it said the flowers were nondescript, but I have use them in flower arrangements every summer. They last as dry flowers for quite awhile.
