Hi Joanna, I am in zone 8a, I have two wonderful plants and have tried to start their seeds to no avail... So, this summer when they bloom again, do I have to do something with the seed right away? I thought I was unsuccessful because the seed doesn't stay viable long at all? So, what should I do with the seed from the mature plants in order to start new plants given my zone? I appreciate all of your advice. I have tried to research this on net a couple years ago without success.
