42 Drought Tolerant Perennials

42 Drought Tolerant Perennials

Why use drought tolerant perennials? There are several reasons why to incorporate them in the garden. To mention a few: plants considered drought tolerant have key characteristics that help them survive moderate to severe drought; planning a drought tolerant garden will conserve one of our most valuable resources – water; and believe it or not you will have a garden jammed pack with lots of color and action. Several of the plants listed serve more than one purpose in the garden than just being drought tolerant. For example: some plants will deter deer and rabbits; attract hummingbirds and butterflies to the garden; herbs for cooking; and lastly used in fresh-cut or dried floral arrangements. And, when you started planning this project of drought tolerant perennials you were thinking dull, drab garden. Right?

Introducing drought tolerant gardening that will have lots of color and action. When planning your garden for drought consider a few things such as light, drainage, soil conditions, and watering. Full sun is the best for all the perennials listed below. The general rule of thumb is an area is considered full sun when the area receives 5 or more hours a day of sunlight. Drainage is essential; when planning the garden do not plant in an area where water collects after rainy weather because the plants will not tolerate wet feet or soggy conditions. Drought tolerant plants do better in soils that are not rich in compost. Save these areas for the plants that liked to be pampered. Even though the plant is considered to have drought tolerance the plant needs to be established in the ground and this usually takes a few months to several months for a plant to be established. Below are a few of the plants listed as drought tolerant perennials.
