Arizona Native Trees and Shrubs That Grow 10 Feet High or Less

When you are looking for low-growing trees and shrubs, those growing under ten feet in height, there are many to choose from. If you are looking to be better to the environment by finding native trees and shrubs that fall into that category, that’s even better. For those in Arizona, these are the native trees and shrubs that will grow under 10 feet tall for your hardiness zones.



Aloysia gratissima

Common Name: Whitebrush, Bee-brush, Privet Lippia, Beebrush

Description: Growing up to 10 feet high, this vanilla-scented plant has small white flowers on spikes and green clustered leaves. Bloom season from March to November. Bark is light gray and there may be sharp-tipped branches. Fruits are drupes, small, and have two nutlets.

Planting Guide: Aloysia gratissima prefers sun or partial shade and moist rocky soils. It does fine in limestone soils as well as sandy or clay soils. It is drought tolerant.

Lifespan: Perennial

Description: This shrub grows 5 to 10 feet high with arched branches and opposite leaves. Flowers are yellow and in small clusters, blooming between January and March. Dark blue fruits are fleshy. Branches help name this as an elbow bush due to their right angles.

Planting Guide: Forestiera pubescens prefers any type of lighting and any type of soil. It is very adaptable and drought tolerant.

Propagation: Stretchberry is propagated by cuttings.

History: It attracts birds and butterflies, especially hairstreak butterflies.
