A water-wise perennial is a plant which, once established, requires infrequent watering (usually less than two times per month) while retaining its aesthetic value. Keep in mind that a perennial considered water-wise in the Northeastern US may not be water-wise in the Southwestern part of the country.
Water-wise perennials are becoming more popular and are available in many commercial venues from large chain store suppliers to independent plant retailers allowing for a wide range of choices appropriate for the local climate.
Many water-wise perennial plants have high ornamental value, flower displays that appear year after year, and are adapted to a wide range of growing conditions.
Select water-wise perennials for the appropriate USDA Plant Hardiness Zone, amount of sun or shade the particular location receives, and mature plant size. A carefully planned perennial bed can provide years of satisfaction, long lasting color, and reduced water use.
