Plants That Need the Least Water in Georgia

Plants that need the least water in Georgia are drought-tolerant plants that can easily adapt to dry spells. Since Georgia is a coastal state with a subtropical climate, water loss can be shocking to many plants. Choose plants that also have a high resistance to pests and the ability to thrive in a variety of soils for best results during periods of drought.

Bougainvillea Golden-Rain Tree

Bougainvillea golden-rain tree (Koelreuteria bipinnata), also referred to as Chinese flame tree or Chinese golden-rain tree, is a deciduous tree that can survive on very little water in Georgia. This upright tree displays yellow flowers, pink seed pods and green foliage. Thriving in full sunlight, the bougainvillea golden-rain tree is adaptable to a wide range of soils, according to the N.C. State University Cooperative Extension. This drought-tolerant plant is pest-resistant and reaches a height of 20 to 30 feet and a width of 15 to 20 feet. Plant bougainvillea golden-rain trees in Georgia hardiness zones 6b to 8b.

Beauty Bush

Beauty bush (Kolkwitzia amabilis) is a highly drought-tolerant plant that thrives in Georgia on little water. A deciduous broadleaf shrub, beauty bush is a pest-resistant upright plant that arches and displays pink flowers during the spring season. Thriving in full sun to partial shade, beauty bush prefers well-drained soil, whether sandy, loam or clay, and tolerates a wide array of pH levels, from 3.5 to 7.2. Beauty bushes grow to a height of 15 feet and a width of 8 feet according to the Virginia Cooperative Extension. Plant beauty bush plants in Georgia hardiness zones 6b to 8b.

Creeping Phlox

Creeping phlox (Phlox subulata), also known as moss pink and moss phlox, is dense, clumping ground cover that displays stiff green foliage and flowers in red, lavender, pink or white during the late winter and spring seasons. Thriving in full sun with tolerance for partial sun to partial shade, creeping phlox grows well in a variety of soils including acid or alkaline, sandy, loam or clay, according to the University of Florida IFAS Extension. Creeping phlox is a low-spreading, pest-resistant plant that grows up to a height of 6 inches. Plant creeping phlox in Georgia hardiness zones 6b to 8b.

Blue Globe Thistle

Blue globe thistle (Echinops bannaticus 'Blue Glow') is an herbaceous perennial with good pest-resistance and a low need for water in Georgia. Blue globe thistle displays vibrant, steel blue, spherical flowers on stiff yellow-green stems. Thriving in full sunlight, blue globe thistle plants can handle a wide range of soils, including dry soil. This perennial plant attracts hummingbirds, butterflies and birds, according to the Washington State University Clark County Extension.
