Anisacanthus linearis (A. insignis var. linearis)


Confined to the Chihuahuan Desert, dwarf anisacanthus grows in the Trans-Pecos in canyons and along dry stream beds and arroyos. Like flame acanthus (A. quadrifidus v. wrightii), it blooms prolifically from late summer through fall with long tubular flowers that can vary from red to yellow. Despite its common name, it can sometimes grow to nearly 10 feet high. "Linearis" refers to the very narrow, linear leaves, 3/4 to 1 1/4 inches long and about 1/10 inch wide. Older stems are whitish with bark shredding into strips. As drought tolerant and sun- and heat-loving as flame acanthus, it has a less compact form and needs a lot of space in the garden. It is root hardy as far north as Dallas.
