Chhitar thor opuntia is a xerophyte, generally found growing on the hill slopes in dry sunny areas, where there is hardly any other deep rooted plant. This bush has an exceptionally long flowering and fruiting season. It is adapted to rapid absorption and storage of water from the infrequent rains of the dry regions. The plant is covered with a thick cuticle which retards transpiration to a considerable extent. In this plant, the leaves are modified into spines, whereas the stem is modified into flat, spongy, leaf-like structures, with the water-storage tissues inside them.
