If we buy from a specialist we can order types which will flower regularly, we can even order according to color, shape and size of bloom. But if we buy haphazard from a market stall, chain store or florist shop we must take our chance.

They store this moisture in their fleshy tissue, which is protected by a thick skin containing a chemical which inhibits transpiration. Their general shape permits them to have the greatest volume with the minimum surface arca. They are, in fact, thoroughly well adapted to their normal wild conditions.

The main oddity about cacti is that they have no leaves. They appear to consist entirely of fleshy stems of various shapes, usually covered or dotted with regular series of spikes or hairs.

So although we should water them quite freely in the summer, for the remainder of the year they should be allowed to become almost dust dry at the roots before watering again and in the winter water should be withheld to the extent that they almost begin to shrink and shrivel before being given a drink. Too much water at any time will lead to root or stem rot. Hence their soil mixture should be exceptionally sharp and well drained.

Cactus flowers are sometimes large and spectacular, sometimes small and insignificant. Colours can be vivid or drab. Some may last only a few hours while others continue open and shining for days.

Epiphytic cacti are not parasites, like our European mistletoe, for their roots do not grow into and absorb nourishment from the tree; instead they use the tree merely as a home, their roots taking moisture and food from the rotting vegetation. As might be expected, epiphytic cacti require different treatment from terrestrial types.
