Cactus

Cactus - Various plants belonging to the Cactus order of plants have proved hardy in England. Opuntia, Echinocereus, Mammillaria, and Echinopsis are among the hardiest. Pretty effects are shown by some Cacti in the open air in Southern England, the plants blooming freely when fully exposed in the sun on a warm rock garden, though the loss of the sun of their native plains is against their being very happy in Britain.

It is well to place Cacti so that they may be safe from injuries, apart from climate, and the best places are, as a rule, on well-drained ledges in the rock garden. In effect they seem out of place in an English garden.
