As I was proposing changes to Supertunia Pretty Much Picasso, there was only one choice allowed for life cycle. Although I left it as "Annual", it's not a true annual, rather a tender perennial grown as an annual in cold zones. Proven Winners lists it as 10A hardy, and as petunias are a winter grower in zone 9 I suspect it could be easily overwintered in Zones 9-11.
How would one show that? Should I have listed it as a perennial, zones 9-11 with Use: Can be used as Annual. Or would that confuse people who think Petunias are true annuals? Or is there a possibility for an "Other" Life Cycle category?
Sorry to keep asking all these questions
