Salvia coccinea

The plants on this page are low care, desert-adapted, perennial herbs. A few annuals also made the list. By definition, these plants lack woody stems. Some may be evergreen and have a shrub shape in regions without frost, but will die to the ground in a hard freeze and regrow in the spring. See Shrubs, Vines and Trees for other flowering plants.
Once established, most perennials listed below will need watering once a month unless it rains. More frequent watering will produce more blooms, however some are intolerant of frequent watering. The most common mistake made with these plants is overwatering once they are established.
Most perennials listed below need well-drained soil which can be found on sloping ground, higher rocky ground or raised garden beds.
Perennials that bloom spring through fall sometimes suspend blooming during periods of extreme heat and start up again in late August unless given part shade and additional water.
Most prefer full sun, some require it to avoid fungal diseases, but others need part shade in high temperatures.
