I planted 100 of these in the hell strip of my lawn to add some interest. I have a corner lot and spread them out over a large space. Did not count to see what percentage actually bloomed, but it is high. Adds a nice color to the lawn. I expect them to naturalize and spread over time. The lawn was getting a little long, so I had to mow and while some of the flowers got topped, there are still a large number of blooms. These exceeded my expectations this first year.
