Ptelea trifoliata subsp. angustifolia, commonly known as Narrowleaf Hoptree, is a deciduous shrub native to arid regions, including desert canyons and rocky slopes in the Southwestern United States and Northwestern Mexico. It typically grows at a moderate rate to a height of 8-15 feet (2.4-4.6 meters) and a width of 8-10 feet (2.4-3 meters). The Narrowleaf Hoptree has compound leaves with three narrow leaflets and bears small, greenish-yellow flowers that are not particularly showy, blooming in the spring and early summer. The plant produces winged fruits that are attractive to various bird species.

The Narrowleaf Hoptree is valued for its drought tolerance and ability to thrive in challenging environments, making it suitable for xeriscaping and naturalistic plantings in arid regions. It is also used as a screen or informal hedge in landscapes. This hoptree prefers full sun to part shade and can adapt to a range of soil types, including clay, loam, and sandy soils, provided they have good drainage. While it is generally low-maintenance, it can be susceptible to scale insects and caterpillars. Gardeners should be aware that the plant may spread by suckering, potentially becoming weedy in some conditions.CC BY-SA 4.0
