Almost everyone knows that acactus can go a long time between drinks, but there are a number of plants in other families -- crassula, euphorbia, and lily -- that can do the same thing. But, what is a cactus and how do you care for it?
Cacti are a type of plant called succulents. They've learned how to compete for survival all over the world.
Cacti from desert areas, like the Mammillaria and Echinocactus, are plump and spiny while those that originally grew in jungle areas are flat or thin and spineless like the Rhipsalis and Schlumbergera.
There are even cacti with leaves. For instance, the Pereskia, when full grown, looks a bit like an orange or grapefruit tree. Other succulents come from a number of families.
The agave, milkweed, lily, and crassula have many members. These plants, with or without spines, all have compact growth habits and lots of character.
This character has caused us to bring them into our homes. In this article, we'll talk about how to care for cactus plants.
