- Emory M.Verified BuyerRated 5 out of 5 stars8/2/26Tall and leggy, definitely prefer a flower net but beautiful
I live in Georgia zone 8a and received these seeds in January so i was a bit worried they would get taken out by the heat but i decided to try and grow them anyways. I started them indoors in February and planted them in my flower bed in March and boy do they take a while to establish. Just when i had nearly forgotten about them they started BOLTING up to the sky in June just in time for our Summer thunderstorms and were immediately pummeled to the ground. Each of these plants grew to about 3 ft tall and put out copious gorgeous almost black blooms through July. These are well worth the effort but definitely need some support (netting is for sure the best)

What an amazing journey from January through the Georgia heat to those gorgeous almost black blooms in July. The fact that you stuck with them through the establishment phase and they rewarded you with such copious, stunning flowers is exactly the kind of growing story we love to hear about! And thanks for sharing that pro tip about using a flower net for support - that's super helpful feedback for other gardeners in similar climates dealing with those summer thunderstorms. Your dedication definitely paid off, and we're thrilled these beauties made it through and put on such an incredible show! Thanks for being part of the growing community with us. Keep on growing 🌻
- MeganVerified BuyerRated 5 out of 5 stars7/25/26Your Patience will be Rewarded
I'm in zone 6b and started some of these by winter sowing and some indoors in a seed snail (ultimately hardening them off in a cold frame). The seed snail seedlings did the best for me. Once in the ground they took awhile to get established but by early July had leapt higher than my zinnias and produced little flower nubs that looked like the center of a black eyed Susan. By mid-July the first bloom had opened to spectacular effect! Rich, beautifully dark petals on incredibly long and sturdy stems - these are a real treat and I look forward to putting them in my bouquets through fall.

Bought from a local nursery— seed packet advertised approximately 20 seeds… my package only had 4. Really disappointing.

- 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.
