Drought tolerant annuals and perennials are plants that can withstand dry soil after their roots are established. No plant is drought-resistant until it become established.
All plants require a steady supply of moisture when first planted. Once a plant is established and has a deep root system, it requires less water.
Annuals and perennials started in spring when the soil is relatively moist can set down roots and then survive dry weather. It is best to start drought-tolerant annuals and perennials in the spot they will grow through dry weather rather than transplant them into the garden when the weather is hot and dry.

Perennial flowers live more than two years. Some perennials live indefinitely. In many gardens, most of the plants are hardy perennials such as phlox, peonies, delphinium, and bleeding heart.
