There are several species of paintbrush in Utah, and each of these may have many varieties. It is often difficult, even for an expert, to be sure of which species he has found. They occur in many shades and colors -- rose, pink, red, orange, yellow, and even white.
The flowers themselves are not very noticeable -- small and greenish. The colored parts which are so showy are actually bracts which surround these flowers.
The plants are often partly parasitic on the roots of other plants, such as sagebrush and rabbitbrush. This makes them very difficult (or impossible) to grow in a home garden, which does not have the needed host plants.

Some of the ones that I have heard mentioned as possibly being found at Albion Basin are:

   Castilleja rhexifolia
   Castilleja linariaefolia
   Castilleja miniata
   Castilleja occidentalis
   Castilleja chromosa
   Castilleja sulphurea

This genus of plants is named for Domingo Castillejo, an eighteenth century Spanish botanist. The region where Castilleja most commonly occurs (the southwestern part of present day United States) was under the jurisdiction of Spain until 1821, so it is not surprising that a Spanish botanist would be the first to study and name the genus.
