- CharityVerified BuyerRated 5 out of 5 stars6/28/26Beautiful flowers!
Love these flowers, they’re so unique in color and shape. I started the seeds using the winter sowing method and they did really well. They did take longer to reach maturity than I expected, but it was fun to watch them grow. Now the plants are covered with beautiful blooms on nice long stem, perfect for bouquets! I will definitely be growing these again.

These flowers are a new love, beautiful & weird & resilient. Bounced back from being literally ground into the ground, still blooming into November.
Want even more next year.
