Succulents

We live in a dry country. It may be hard to see, given the wide green lawns and tall trees grown on stolen water. People less concerned with watering plants (whether because they are more interested in saving water or less interested in dealing with them) like succulents, plants which, with their thick stems and leaves store more water than normal plants. They have a waxy substance that prevents them from losing moisture.

Curiously, succulence is not an indicator of close genetics but of convergent evolution (where two or more species develop similar characteristics based on environmental factors.) Because they are members of different families, they can have a vast number of features, from needles and hair to leaves and flowers. Some are regular and look almost like roses, others have leaves and flowers. Succulents in and around LA include ice plants, money trees and aloe vera plants. Some cacti and orchids are also succulents. None grow here naturally.
