Where can I buy sun spun Burgundy petunia plants online? Can I buy seeds or leaf starts? I have been looking for them for a couple of years and need your help..Thank you.

The plant trade industry cranks out new improved cultivars and series every year so these older ones fall out of circulation. This particular one was added to our database back in 2015 so most likely much older and photos were never added to it meaning we didn't have any members growing it.
I'm sure you could find something similar in the spring.
