Best Cold Hardy Tropical Plants for Cooler Climates
You can’t get much more tropical than a banana tree.

Sadly, these banana plants won’t produce edible bananas. But they will delight you with their broad tropical leaves and vigorous growth.
Cold hardy tropical banana plants can grow up to 13 feet tall. Cut your hardy banana tree to the ground after the first frost and mulch heavily over the stumps. This will protect the tough “tropical” plant so it can survive temperatures below zero degrees Fahrenheit.
Toad lilies (Tricyrtis sp.) are not nearly as popular as they deserve to be. These cold hardy tropical plants have a wonderful, exotic flair with their uniquely intricate blooms. As if that wasn’t enough, the plants are surprisingly tough.
Toad lilies are prized for their attractive foliage for most of the year. But starting at the end of every summer, they dazzle as they burst into bloom. These lilies prefer partial shady areas with rich, loamy soil. The Raspberry Mousse Toad Lily is a classic look for these delightful flowering plants. The flowers show a base of white with a splattering of raspberry purple on the petals. The centers show a flash of yellow to make the flowers really pop in a garden setting.

Tips on Growing Cold Hardy Tropical Plants
Most of the cold hardy tropical plants featured here do not require much specialized care. But it helps to be prepared and to do your research before buying.
1. Read the Label
Like all plants, cold hardy tropical plants have specific light, water and soil needs. Do your research, beyond just checking your USDA Growing Zones, to make sure you can provide for your new plant’s needs.
Most of the cold hardy tropical plants mentioned here can withstand very cold temperatures. But they require high humidity and consistent moisture to thrive.
(Sorry, desert gardeners. You’ll have the best success growing these plants in a humid indoor environment. So, grow tropical plants in a greenhouse. Read Backyard Greenhouses for Every Budget for more info.)
2. Mulch, Mulch, Mulch
Mulching is always a good idea. For tender tropical-looking plants, it’s a 100% requirement. Do not skimp on mulch! Mulch will keep weeds down and make your garden beds pretty. It also insulates your plants’ roots against hot and cold temperatures, and it is vital for retaining moisture in the soil.
3. Water Properly
With a few exceptions, such as the Toad Lily, most plants prefer to be watered deeply. After watering, allow them to dry out a bit before you water them again. Rather than taking the “little and often” approach, water thoroughly—but only when your plant needs it.
The success of growing tender plants (like the hardy banana) at the edge of their growing zone comes down to winterizing properly. In Zones 5 and 6, for example, you will need to cut your banana to the ground and mulch it with a pile of straw for extra protection from the cold.
Other plants, such as the fig tree, may also need to be brought into a shed or garage to sit out the winter cold. Do your research on proper winterizing before you bring a cold hardy tropical plant home. This is especially true if your garden is at the colder edge of its growing zone.
