As with many other members of the Castilleja genus, Wyoming Indian paintbrush, the state flower of Wyoming, is native to several states in western North America. If you’re interested in Castillejas, don’t miss Mark Egger’s superb photographic compilation on Flickr. They appear from April to October. See also this Castilleja comparison table.
Identification: Plants are 12-40' (3.7-12 m) tall, and often branched. (Plants sometimes approach 6½' (2 m) in height.) Initially grayish-green, stems and leaves become tinged with purple over time. Leaves are linear, long and narrow, usually entire (undivided), though sometimes upper leaves are lobed. They are often curled, appearing almost tubelike. Flowerheads are ⅞-2" (2.5-5.2 cm) in size. Bright red bracts (modified leaves) about 1¼" (3.4 cm) long mostly hide drab yellow-greenish flowers within. Flowers appear from May to October. Fruits are two-chambered capsules.
