Little Leaf Ash
Fraxinus greggii
A compact Chihuahuan Desert shrub with pale pink-white spring flowers that attract bees, butterflies, and moths.
Hardy in USDA zones 7-11; a cold-tolerant Chihuahuan native that handles mid-desert freezes and low-desert heat, deciduous in colder winters.
AMWUA Notes
A moderate-water Chihuahuan shrub with strong early-spring pollinator value; drought tolerant once established.
Care Guide
Water deeply every 10-14 days in summer; it is fairly drought tolerant once established but keeps fuller foliage with periodic moisture.
Prune lightly in late winter to shape; it can be grown as a large shrub or small multi-trunk patio tree and does not need shearing.
A light spring feeding supports growth in lean soils.
Generally trouble-free; watch for occasional aphids on new growth.
Semi-evergreen to deciduous depending on winter cold; pale spring flowers draw pollinators and the fine foliage can show yellow fall color before dropping in harder winters.
