Castilleja integra
Also called Foothills paintbrush, Wholeleaf Paintbrush
Castilleja integra is a partially parasitic perennial from the Southwest US and northern Mexico, grown for its red-orange bracts and nectar that attracts hummingbirds. It is one of the easier paintbrushes to grow in dry, open, sunny sites such as xeriscapes and meadows.
Castilleja integra, with the common names orange paintbrush, Southwestern paintbrush, and wholeleaf paintbrush, is a partially parasitic herbaceous perennial plant native to the Southwestern United States and Northern Mexico. The species produces a relatively large amount of nectar and is attractive to hummingbirds. It is better suited to cultivation than most other species in the paintbrush genus (Castilleja) and is therefore used in xeriscape gardens and naturalistic meadows, even outside its native range.
The natural range of Castilleja integra can be broadly defined as northern Mexico and the southwestern United States. In the United States its range includes Arizona, Colorado, New Mexico, and Texas, but it not found in California or Nevada. It also grows in much of northern Mexico including the states of Baja California, Sonora, Chihuahua, Coahuila, Nuevo León, Tamaulipas, and Durango. The distribution of elevations is quite wide for this species, most often 1,000 to 3,300 meters (3,300 to 10,800 ft) and they may be occasionally be found all the way down to 600 meters (2,000 ft).
