Flowering maples are not even maples. They are not hardy.

I wonder how your flowering maples are doing. I grew them in Orlando FL in blistering heat and full sun. They grew, but seemed much less full and lush than in pictures. I always thought they would have done better in a more filtered sun situation, or maybe with only morning sun, but I didn't have those conditions. At the end of the season, I took them down and put them in the garage, where they continued to put out new leaves for awhile. By spring, they were still viable, but I didn't feel like messing around to try to rejuvinate them, so went on to something else. I'd like to give them another try because they're so pretty.

I have them on the front porch of our 1850's farmhouse, where one gets morning sun and the other gets it in the late afternoon. So far, they look wonderful. I pinched one back a bit because it was too leggy, and it's filling in nicely. They'd probably be doing better, but I am in the process of renovating the entire house, so I don't have the time to give the plants and yard too much attention. I'll have to update you later as I learn more.
Cheers and Fairwinds,
