Tropical plants; Cold and frost hardy tropical plants

buy cold hardy tropical plants online

We get many inquiries regarding growing tropical plants in gardens which are prone to frost. It certainly is possible to grow tropical plants, or tropical-looking plants, in frost prone areas, as proven by many stunning tropical gardens.

Not only are there tropical plants which can actually handle frost, including some palms which can handle temperatures of up to -10 degrees, but there are many things you can do to increase the overall temperature in your garden by creating a 'micro-climate', or to increase the temperature in one spot, around a plant which needs it.

Green-, or glass houses, are a great way of growing tropicals in the cold as it keeps humidity high and frost out. Christmas lights can be wrapped around shrubs and trees to increase the air temperature, and brick pavements and walls are known to absorb heat in the sun, and release it when it gets cool, benefitting the plants around it.

Frost often settles from above, so a shade roof can be a great help to keep frost off your plants. Mulch will help keep the ground insulated and warm.

Below are some examples of tropical plants that can handle frost or cold.
