I've got an area that needs filled, and I was thinking of getting a Hawaiian Ti (Cordyline Fructicosa) to put in it. I'm in zone 9a. It would get mostly sun. I see them planted all around, but when doing research online, I found that they are best suited for zone 10 and above. Anybody in this zone having luck planting this outdoors? Any info is truly appreciated! Thanks in advance.
