Agarita shrub in its natural habitat

Berberis trifoliolata, commonly known as agarita, agrito, or algerita, is a species of flowering shrub in the Berberidaceae family. This plant is native to the southwestern United States and northern Mexico, where it thrives in arid and semi-arid environments. It is well-known for its distinctive trifoliate leaves and bright yellow flowers.

Description

Form of Berberis trifoliolata

Berberis trifoliolata is a perennial shrub that typically grows to a height of 1 to 2 meters. The plant is characterized by its rigid, spiny branches and trifoliate leaves, which are composed of three leaflets. The leaflets are leathery, with a bluish-green hue, and have serrated edges.

In spring, the shrub produces clusters of small, fragrant yellow flowers. These flowers are followed by the development of small, round berries that mature to a bright red color. The berries are edible and are often used in making jellies and wines.

Habitat and Distribution

Berberis trifoliolata is commonly found in rocky, well-drained soils in regions such as the Chihuahuan Desert, Trans-Pecos, and the Edwards Plateau. It is adapted to survive in harsh conditions, including drought and poor soil fertility.

Cultivation
