The Indian paintbrush is my favorite native flower especially because it blooms at the same time as the bluebonnet, creating this beautiful carpet of reds and blues lining every highway in Texas making any road trip worth your while.
Castilleja, commonly known as Indian paintbrush or prairie-fire, has about 200 species of annual and perennial plants native to the west of the Americas from Alaska south to the Andes, northern Asia, and one species as far west as the Kola Peninsula in northwestern Russia. These plants are classified in the broomrape family,
The Indian Paint brush we are so familiar with is the (Castilleja indivisa Engelm, Entire leaf indian paintbrush, Texas paintbrush, Indian paintbrush, Scarlet paintbrush, or the Entire-leaf indian-paintbrush) One of the popular paintbrushes, this annual or biennial grows 6-16 in. high. It has several stems that form clumps topped by bright-red, paintbrush-like spikes. The flowers are actually inconspicuous and greenish, but do have beautiful showy, red-tipped bracts. They sometimes produce a light yellow or pure white variation mixed in with the reds. Together, the flowers and bracts form 3-8 in. spikes.
TRADITIONAL — USES
The flowers of Indian paintbrush are edible, and were consumed in moderation by various Native American tribes as a condiment with other fresh greens. These plants have a tendency to absorb and concentrate selenium in their tissues from the soils in which they grow, and can be potentially very toxic if the roots or green parts of the plant are consumed. Indian paintbrush has similar health benefits to consuming garlic if only the flowers are eaten in small amounts and in moderation. The Ojibwe used a hairwash made from Indian paint brush to make their hair glossy and full bodied, and as a treatment for rheumatism. The high selenium content of this plant has to be the reason for its effectiveness for these purposes. Nevada Indian tribes used the plant to treat sexually transmitted diseases and to enhance the immune system.
