There is also the added question about climate and sunlight. What about a garden in dry shade? Is it possible to have color and plants in a shady yard when water is scarce? One colorful and exotic plant to consider are epiphyllums, whose colorful cactus flowers will fill a shaded yard or patio every spring.
