Plants That Like Alkaline Soil

Plants can be placed in three types of soil: neutral, acidic and alkaline. After a pH test you will know what type of soil you have in the area that you are planting. Remember that soil pH can change from spot to spot so it is important to test all the areas that you are going to plant. For plants going in a non-acidic soil spot, in alkaline or limey soil, there are plants that will thrive.

Eastern White Cedar

The eastern white cedar or American arborvitae, botanically known as Thuga occidentalis, is an evergreen tree that gets 40 to 60 feet in height. Leaves are scale-like and fragrant, a yellow-green in color that will mature to a winter bronze. Cones will change from green egg-like structures to red-brown in color in the fall. Propagation should be from seed or by semi-ripe cuttings and grown in full sun or partial shade in moist, non-acidic soil. Eastern white cedar is hardy in USDA Plant Hardiness zones 2 through 7.

Deodar Cedar

The deodar cedar, botanically known as Cedrus deodara, is a fast-growing evergreen tree that is drought-tolerant. It averages 40 feet tall but has the potential to reach 200 feet in height. Leaves are 2 inches long and needle-like with 3- to 5-inch blue-green cones. Propagation should be from grafting or seed and grown in full sun in neutral to alkaline soil. USDA hardiness zones for a deodar cedar are 7 through 9.

Blue Hesper Palm

The blue hesper palm or Mexican blue palm, botanically known as Brahea armata, is an evergreen drought-tolerant palm. It will get 50 feet high and 16 feet wide with blue, blue-white or aquamarine colored fronds. Flowers are in clusters and are white with brown-black fruits three-quarter-inch wide carrying one seed. Propagation should be with seed in moist, well-drained, non-acidic soil in full sun or partial shade/sun. Hardiness zones are 8 through 11.

Barbados Silver Palm

The Barbados silver palm or thatch palm, botanically known as Coccothrinax barbadensis, is an evergreen palm that attracts birds. It gets 8 to 50 feet in height. With fronds that are 40 inches wide, colors are silverish white underneath the foliage and green on the top. Propagation should be by seed in full sun with non-acidic soil that gets regular watering. The USDA hardiness zones for a silver palm are 9 through 12.

Silk Tree

The silk tree or mimosa, botanically known as Albizia julibrissin, is a fragrant fast-growing tree that is also drought tolerant. It gets to 35 feet in height with 12-inch-long feather-like leaves. Flowers are pink, in clusters 6 inches wide, and fragrant. Propagation should be from seed in full sun or partial shade in any soil (alkaline is fine). Hardiness zones of the silk tree include 6 through 9.
