Candee - I got a bunch of zinnia seeds this year, with great intentions to sow them. But, that did not happen, so will have to wait until next year to try again. Yours look great.
Trish - I live in zone 9a so I am able to leave my dahlia tubers to overwinter in the ground. But, since I was told to divide my tubers at least every 2-3 years, I will need to dig some up this year. I will be happy to send you some tubers.
In regards to peonies, there should be some that grows in 8a. Which ones have you tried?
