A cactus is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. Cacti are succulent perennial plants. Cacti generally have thick herbaceous or woody chlorophyll-containing stems.
Cacti can be distinguished from other succulent plants by the presence of areoles, small cushionlike structures with trichomes (plant hairs) and, in almost all species, spines or barbed bristles (glochids). Areoles are modified branches, from which flowers, more branches, and leaves (when present) may grow.
As a plant used for landscaping projects for both private homes and public paces and business premises, they are very popular. There are many garden centres and retailers listed in this category who grow and propagate cactus who will be found here.
