There are a wealth of plants that will thrive in a hot, south-facing aspect plants with silver or hairy foliage are well adapted to the heat such as Lavender, Eryngium (Sea Holly) Sea Holly Californian poppies (Eschscholzia) and Marguerite daisies (Argyranthemum). You could also try night-scented stocknight scented stock for a beautiful fragrance. There are lots of bedding plants that you could try. A lot of bedding plants originate from hot countries, such as Petunias, Zinnias, annual Verbenas, Gazanias and Gaillardias. A favourite is a plant with succulent leaves called Mesembryanthemum (Livingstone daisy) and similarly Delosperma. They look stunning when planted en masse.
