Melia azedarach
Some crops are grown under the protective shelter of different kinds of plant, whether as wind breaks or for shade. For example, shade-grown coffee, especially "Coffea arabica", has traditionally been grown in light shade created by scattered trees with a thin canopy, allowing light through to the coffee bushes but protecting them from overheating. Suitable Asian trees include "Erythrina subumbrans" (tton tong or dadap), "Gliricidia sepium" (khae falang), "Cassia siamea" (khi lek), "Melia azedarach" (khao dao sang), and "Paulownia tomentosa", a useful timber tree.
