Summary

Aloysia macrostachya, commonly known as Rio Grande Beebrush, is a shrub that can be either evergreen or deciduous depending on the climate, native to the semi-arid regions on ridges and bluffs in Central and Northeastern Mexico. It typically grows to a height of 9-12 feet (2.7-3.7 meters) and a width of 7-10 feet (2.1-3 meters), featuring an open and airy growth habit. The plant is adorned with narrow, lance-shaped leaves and produces clusters of small, fragrant purple flowers in the spring, which are highly attractive to bees and other pollinators.

Rio Grande Beebrush is valued for its aromatic foliage and the profuse, showy blooms that provide a nectar source for beneficial insects. It is used in xeriscaping, as a specimen plant, or as part of a wildlife-friendly garden. This shrub is drought-tolerant once established, requiring only medium amounts of water, and thrives in well-drained soils. It prefers full sun but can tolerate some light shade. While generally low-maintenance, it may be susceptible to root rot if overwatered or planted in poorly drained soils. Pruning can be done to maintain its shape and encourage denser foliage.CC BY-SA 4.0
