Plants That Live in the Humid Subtropical Region
The humid subtropical region can be a challenge for many gardeners who are used to a more temperate climate. Generally it is defined as having no freezes and few if any frosts and rain or fog is abundant. This presents a problem for some traditional plants but also opens up a wide range of possibilities for growing new, beautiful plants.

Temperatures
-
Depending on the region, temperatures might range from a low of 35 degrees F to highs in the 100's with rare light frosts. The lack of cooling days prevents many temperate plants from doing well and temperatures below 45 degrees kill many true tropical plants. Fortunately there are many colorful, fruitful subtropical alternatives.
Flowers
-
Petunia, pansy and other traditional summer flowers do well in the winter in the subtropics. Allamanda, impatiens, roses (on the proper rootstock) and orchids excel. Many orchid collections thrive in the subtropics.
Foliage
-
Subtropical foliage can be highly colored or unusual in size and form. Philodendron and Monstera have huge leaves while delicate Peperomia stand out with silver or white variegation. Gingers can add color with both flowers and variegated leaves. Ferns such as maidenhair and birdsnest add to the tropical feel. Cycads and tree ferns produce an almost prehistoric atmosphere.
Trees
-
One of the most prominent trees is the ficus with hanging aerial roots and buttresses supporting huge spreading trunks. Lipstick tree (bixa) has pink flowers. Palms in all shapes and sizes are available for any planting, from the small Chamaedorea to huge coconuts.
Fruits
-
Besides the common citrus sugar apple, papaya, lychee, mango and pineapple are found in hundreds of varieties. The much promoted miracle fruit does well in the subtropics. These and others can be available for picking just outside your door.
Special Considerations
-
The subtropics provide an opportunity to grow tasty and nutritious fruit as well as colorful flowers and foliage. You need to think before you plant; growth can be quick and a little forethought can prevent problems as the garden matures.
