Both my red Southern Belle and my pink oak-leaf style ones seem to have pods that are producing seeds this year. I don't think they ever have before. I was able to collect some from the red one yesterday.

I think these are the type of seeds that may benefit from Winter sowing.

I'll collect as many as I can and will have some to share soon. I'll post again when they are ready to go.

Disclaimer: I have never grown these from seed.

Here is the red one:

The pink one is actually a larger plant and is a profuse performer.
