I winter sowed these seeds and have had fantastic germination with them. They’re not quite big enough to be transplanted out yet, but they’re getting more leaves and look to be strong seedlings. I can’t wait to see them bloom once they’ve gotten established, even though it may be quite a wait since it’s a perennial!

These were lovely flowers on 2-3 ft stems. I started in seed trays and transplanted 4 plants to a berm. Bloomed late May and I'm still getting a few stems of flowers pop up in August. 3 of the 4 were yellow so I planted more this year. They were also rabbit resistant in my yard!
