About plant names...

Texas Indian paintbrush is a North American native, but it isn’t found in Texas at all: it is found in northern Baja California and California. If you’re interested in Castillejas, don’t miss Mark Egger’s superb photographic compilation on Flickr. See also this Castilleja comparison table.

Identification: Plants are 12-24" (30-60 cm) tall, multiply branched, coated with a “felt” of white to gray, branched hairs. Leaves are ⅜-1¾" (1-5 cm) long, mostly linear (long and narrow), sometimes forked. Flower clusters are 1-8" (3-20 cm). Each flower is ½-⅞" (1.5-2.5 cm) in size, surrounded with bracts (modified leaves) of similar size. Flowers are orange-red or sometimes yellow-green in color, appearing from March to June. Fruits are ⅜-½" (1-1.5 cm) long, with seeds that are ¹/₃₂-¹/₁₆" (1.5-2 mm).
