This is a wild flower you want. It blooms relatively late. This one July 14. A single plant lasts for years as it develops a tuber below ground and comes up each year from that. When you find a plant, and they are many, collect the seeds, which are obvious. . .and good luck. Many of these “weeds” sprout when and where they want.
Neighbor Norm possesses this plant which he sometimes forgets and mows over. As stated above, it starts very late and can be mistaken for an unwanted “weed.” One person I know places rocks around his to remind him of the location each year.
