About Whitebrush

Whitebrush, also called Beebrush or Whitebush, is a slender deciduous shrub native to Texas, the southwestern United States, and Mexico. Reaching 3 to 9 feet tall with willowy branches and small narrow leaves, it bears intensely fragrant clusters of tiny white flowers in flushes after summer rains. The vanilla-honey scent perfumes Texas and Southwest landscapes from late spring through fall, attracting clouds of bees and butterflies.

History

Illustrated historical scene for Whitebrush

Aloysia gratissima, commonly called whitebrush, beebrush, or fragrant mist flower, is a deciduous aromatic shrub native to dry slopes and brush country of west and south Texas, New Mexico, and widely through Mexico and into South America. French botanists Bonpland and Kunth described it in the early 19th century. The small white flowers, produced in terminal spikes after rains, release an exceptionally sweet vanilla and almond fragrance that perfumes brush country air after thunderstorms.

Texas and Mexican beekeepers prize the plant as a premier nectar source, producing a pale amber honey. Ranchers historically distrusted it because cattle can develop neurological symptoms after prolonged browsing.

Xeriscape gardeners increasingly use whitebrush as a fragrant, drought-tolerant flowering shrub and pollinator magnet in hot dry climates. The intense vanilla fragrance has long been celebrated by Texas naturalists, and the plant is a staple of pollinator-focused native gardens promoted by the Lady Bird Johnson Wildflower Center.
