Answer: Hot dry situations in the garden can prove difficult for any plant that is not adapted to cope. Such sites present a challenge to plant survival because of the lack of moisture needed for plant growth and leaves that will scorch in very hot sun. Complicating the issue is that containerized plants will often suffer from root problems because the containers hold the heat and essentially bake the roots. You'll have better success with your containerized plants if you group the containers together so they can shade one another.
Plants that will thrive in these conditions have characteristic which are beautiful and practical. Grey, silver and blue leaved ones that are clothed in fine hair or have a waxy surface deflect the burning suns rays. Plants with fragrant foliage exude volatile oils which form a haze around the plant and act as a sun block. Then there are succulent plants of low neat habit whose thick and fleshy leaves store water to prevent dehydration. Many sun loving plants perform best on soils that are not to fertile. High nutrient levels can produce soft sappy growth that is more susceptible to damage by cold and wet in winter. Some recommendations include
Senecio cineraria Silver Dust
Verbena Homestead Purple
Erysimum Bowles Mauve
Grevillea Canberra Gem
Cistus Silver Pink and Peggy Sammons
Verbena Peaches and Cream
