Lime pricklyash

Zanthoxylum fagara

(colima, wild lime, uña de gato)

DESCRIPTIONLime pricklyash is a prickly, intricately branched, evergreen shrub that grows 5–20 ft. tall, forming a somewhat rounded crown with bright green, alternate, odd-pinnately compounded, oblong, aromatic leaves on a broad-winged rachis. The leaves are bitter to taste and smell like citrus or lime when crushed, hence the name. The tiny, greenish-yellow flowers bloom from March to June followed by clusters of small, round, smooth, rusty brown to black, single-seeded fruit that ripens in late summer or early fall. The thorns are recurved, therefore similar species are catclaw acacia and Roemer acacia, but without a winged rachis.

Lime pricklyash is commonly found throughout south Texas and is often associated with honey mesquite, pricklypear cactus, and wolfberry. It grows in a variety of soils, from shallow rocky soil to deeper clays and sandy loams. Lime pricklyash easily reestablishes when disturbed and readily resprouts from the base when the aboveground biomass is removed by roller chopping, shredding, disking, or other means. It can become a brush management problem in heavy clay soils following disturbance by mechanical treatments.
