I am trying to save Gaura seeds from a commercial cultivar that did well in my yard, and overwintered from last year..
It appears the little seed (pods?) generally detach themselves as soon as brown/ripe, but I have found a few. Probably I should have put a nylon stocking over it.
I thought the little brown "pods" were probably holding multiple seeds, but they never seem to open up to release any seeds, and so I cut one open with a knife. I found a single very alive looking "seed" inside, not multiple seeds. The capsule is very hard. So here are photos. Do you agree the brown thing is the actual seed? I need to know if I need to do anything else prior to storage. And for sprouting next year would it need soaking or scarification?
