I love foliage plants in my garden and Coleus is always one of my favourites.
The beautiful leaves give you so much colour that is so vibrant.
In the UK you need to treat them as an annual as they are not hardy enough to cope with our colder temperatures. Unless you plan to grow them in a container and bring them indoors when the frosts return.
For outdoor growing, plant them in either a sunny or shady spot in moist but well drained soil.
