The three I have are about 4foot tall and still in their pots. I had the most wonderful lemon scent in the shop this last month when they bloomed. I have the plant neon blubs and they think it is sunshine. Now the orange is beginning to bloom.
Just incase someone doesn't know, this is the Giant Swallowtail pic. I raise and release them in my yard to lay more eggs on my plants...and on we go. It is this butterfly that uses the citrus trees for it's host plant. So I don't spray pesticides in my yard where it would kill my caterpillars.
