The caper bush requires a semiarid or arid climate.
The caper bush has developed a series of mechanisms that reduce the impact of high radiation levels, high daily temperature, and insufficient soil water during its growing period.

The caper bush has a curious reaction to sudden increases in humidity; it forms wart-like pock marks across the leaf surface.
This is apparently harmless, as the plant quickly adjusts to the new conditions and produces unaffected leaves.

It also shows characteristics of a plant adapted to poor soils.
This shrub has a high root/shoot ratio and the presence of mycorrhizae serves to maximize the uptake of minerals in poor soils.
Different nitrogen-fixing bacterial strains have been isolated from the caper bush rhizosphere, playing a role in maintaining high reserves of that growth-limiting element.
