    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!

    I have these flowers planted in front of my home. I started them last year (2017) from seed and planted them out last year. As it says on the packet, they will not flower the first year and they didn't for me. We have about 15 plants out front and the predominant color is yellow. The blooms are 3 large as noted. Colors we have noted are red and yellow, yellow, pink and yellow, purple and white, and white. We have not had any of the pink and white or blue and white as show in the illustration. Finally it should be noted that these plants are NOT deer resistant. The deer have grazed them 4 times already this summer (2018) but they do come back within 3-4 weeks. Very pretty and very low maintenance in my opinion. I have not fertilized and water once a week.
