Buddleja marrubifolia is a species endemic to the Chihuahuan Desert from southern Texas to San Luis Potosí in Mexico, where it grows on limestone and gypsum soils in canyons and arroyos at elevations of 600 - 2,250 m.[1] The species was first named and described by Bentham in 1846.[2]
B. marrubifolia is a dioecious multi-branched shrub 0.5 - 2 m high with greyish to blackish rimose bark. The young branches are terete and tomentose, bearing ovate to rhomboid leaves 1 - 3 cm long by 0.6 - 1.5 cm wide, membranaceous to subcoriaceous, and densely tomentose on both surfaces. The inflorescence is a terminal globose head 0.8 - 1.2 cm in diameter, comprising 35 flowers, deep yellow turning orange; the corollas 2 - 3.5 mm long. [1]
The shrub is cultivated at the University of Arizona, Tucson, and is planted as an ornamental in Hawaii. [1]
