Can I grow Bougainvillea in zone 7A Maryland?
I love the look of Bougainvilleas. However, I live in the DC suburbs of Maryland, in zone 7A. Is anyone else zone pushing with these?
I was thinking of attempting to grow them outdoors against a south facing brick wall - this place stays warm - with added winter protection like wrapping. I would be okay if it behaves like a perennial, provided I get flowers. Is this possible? Which varieties would be appropriate?
