The species Buddleja davidii is naturally a mauvy/purple colour. The other colours are hybrids and therefore cannot be guaranteed to come true from seed. You'll just have to wait and hope that you get something interesting.

Christin, I've read that both Doppleganger/Doubledecker and White Swan are seed strains so they should both be good, I hope your coneflowers turn out spectacular. I know folks have been collecting and sowing seeds from those hybrids and I sure haven't seen much encouraging news on this thread so I'll keep my fingers crossed for you. Even though I knew I shouldn't, I started drooling when I ran across Pink Double Delight seed on a trade page I was browsing last night. How I managed to restrain myself from sending an email, I'll never know. Lol. Terrene, they look fantastic, I can't wait to see them in bloom! I kinda stalk the daylily threads so if you post pics I'll surely run across them! I started all my daylilies in red drink cups and a lot of the smaller plant starts that I take to the swap go in recycled easy mac bowls, which my son was addicted to a few years ago. T-bird, that's exactly what I'm talking about. I'm frugal as can be and almost all the seeds I start are from trades. I know that other folks have been growing seeds from trades and I haven't grown an Echinacea since the '90's so I figured I would save myself a bunch of trial and error and just ask others their opinions. Folks on GW are great, I never go wrong following the collected advice here. Jeanne

Since these are a new hybrid cultivar, do you think seeds will reproduce true to parent? Runners would be better, I think.

Hi Northern, Yes it holds true. Good Echinacea seed are light brown and hard. I find a mix of good and bad echinacea seeds when separating them from the chaff. The link below is of a close up of echinacea seeds. The seed to the left is flat and definitely no good. There is also a similar bad one to the bottom right. As you can see they are sort of 4 sided and when good do not sink in. The wet summer will not make the seeds go bad. It could however cause a lower amount of good seed because pollinators can not effectively do their job to cause seed development. For example if it rains a lot, butterflies who love echinacea, will not be out or only for brief times so pollen mixing is not going to occur. I'm interested to know where you read the article because it doesn't make any sense. Some seeds are inside of fruit, but not all. Plus fruit rots and seeds do not so to say we are saving fruit is incorrect. Remy Here is a link that might be useful:
