Gardening with Tropical Plants

Learn About Gardening with Tropical Plants

Tropical gardens can vary from dry and desert-like, to coastal, to dense, lush and leafy environs resembling the dynamic workings of a rainforest. Many different garden effects are possible using tropical plants.

Certain plants that originate in tropical or sub-tropical climates can sometimes be grown successfully out of doors in a cooler climate - particularly if provided with some protection (e.g. under the canopy of a large tree or beside a wall to protect from wind and/or frost). With the right conditions (i.e. light, ventilation, temperature, humidity etc) any tropical plant can be grown in a greenhouse, or as an indoor plant, no matter where you live.

This course aims to provide a sound introduction to gardening with tropical plants, in greenhouses, protected garden spaces, indoors or in warmer climates. It provides a good first step for anyone new to horticultural study, whether amateur gardeners, volunteers or aspiring professionals.

NOTE - This course is based on our "Tropical Plants" course - adapted to be more suitable for entry level students.

WHAT DOES THE TERM ‘TROPICAL PLANT’ MEAN?

Some people would think a tropical plant is a plant that comes from the tropics. Others might consider tropical plants to also include plants from sub-tropical places.

Gardeners in some parts of the world would also consider any plant that has a tropical appearance, to be a tropical plant.
Cordylines for instance, are often called ‘tropical plants’, even though many of the common cultivars have at least partially originated in New Zealand, which does not fall within the tropics.

This course is concentrating on plants which originate from tropical or sub-tropical climates; but there may be some plants covered which fit a looser definition of ‘tropical’.
