This tender perennial is native to the tropics and sub-tropics of the Americas, Africa, Asia and Australia. I have found various Zones applied to it, with 8b and 9 the most common. I would believe that it could be root-hardy to 20°F if established in the ground in a protected location. It lends itself to container growing as well, and can do well in a sunny window in the winter.
Flowering Maples do best in filtered shade, dappled shade or part shade in Central Texas. I would definitely protect it from the afternoon sun. They have a very long bloom season, starting early in the spring and lasting into the winter if protected.
Grown either as a “tree form” or “shrub form” these plants can grow to about 6′ by 5′-6′.
Pruning and shaping after a big bloom will keep the plant tidy and encourage more blooms.
Fertilizing with a blooming plant fertilizer monthly from March to September will keep the leaves dark green and blooms coming. I use Nelson Plant Food’s Color Star time-release fertilizer.
Use a quality potting soil such as Happy Frog Potting Soil when planting in pots. Allow the top of the soil to dry between waterings, keeping the soil on the moist side. Water thoroughly when you water and do not allow pot to sit in saucer of water.
