Poponax is a small deciduous tree or shrub which in habitat may grow to 30 feet tall and is common to disturbed sites. The trunk has light brown bark with darker streaks. The crown of feathery foliage is thin, irregular and flat on top. Branches grow upward and bear compound leaves 1-3 1/2 inches long with numerous small soft leaflets; small branches have spines. Flowers are borne in clusters in leaf axiles and are tiny, yellow-orange fragrant blooms which attract bees and insect pollinators. Fruits are woody pods, covered with downy hair, dark brown to black often curved and up to 5 1/2 inches long containing ovoid seeds. Propagation is by seed or cuttings. The wood is good as fuel. Livestock eat the leaves and pods. As a pioneer species, poponax is a hardy tree or shrub, suited to any well-drained soil type; it tolerates salt spray. It is a good tree for land reclamation. As an ornamental plant, its delicate foliage and showy flowers make it a good specimen or accent tree, or it can be grown as a sturdy shrub. It is suitable in parking lots for shade, and along streets and in medians. Poponax also can be successfully trained as a bonsai plant.
