Can You Grow Tropical Plants in Cold Climates?
Despite being challenging, growing tropical plants in colder climates are possible. Some of them are cold tolerant. Thus they can withstand low temperatures with minimal issues. However, you must determine the hardiness zones of each plant because they have different tolerances to cold temperatures.
Take dwarf palmetto as a great example. It is a cold hardy palm tree that can grow in the U.S. hardiness zones 6 to 10, meaning that it may suffer from cold winters in an earlier climate zone. The smaller the zone number, the more extreme the winter temperatures will be.
The Lowest Temperature Tropical Plants Can Tolerate
Generally, tropical plants love temperatures between 60°F to 65°F. Most of them cannot tolerate temperatures lower than 50°F. Such conditions may lead to frost damage that inhibits your plant growth. It will, especially, greatly influence the younger plants which have not been fully established. Some of the characteristics of frost damage shown are the appearance of brown patches on the leaves before they wither and die.
However, there are plants that look tropical and can survive low temperatures down to -30°F to -40°F. One of them is hardy hibiscus (Hibiscus Moscheutos) and maidenhair fern (Adiantum pedatum).
They thrive in the U.S. hardiness zones 5-8 and 3-8, respectively, which span the far northern parts with quite extreme winter temperatures. So, determining the lowest temperature that can be tolerated by tropical plants really depends on the type of plant.
How Do Tropical Plants Adapt To Cold Weather?
Although not all tropical plants can handle cold, some can survive growing in low winter temperatures. But how do they adapt to conditions outside the optimum temperature for their growth? They usually drop their leaves to reduce the evaporation process (transpiration). Thus, saving a lot of water from within the plant.
In addition, this way of adaptation also narrows the surface area that can be exposed to cold air. And instead of growing large leaves, they reduce the growth size and produce crowd foliage. It is beneficial to prevent free air circulation, which can potentially bring cold air, which may be damaging to the plants.
Hardy Tropical Looking Plants for Cold Climates
For those of you who live in the northern part of the U.S. but want to design a tropical garden, we have some tropical-looking plants for the cold climate you can try planting. They are versatile and easy to maintain, so you don’t have to worry about growing them outdoors.
