Learn about Gardening with Tropical Plants

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.

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’.  It 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.
