About plant names...

This variety of longleaf Indian paintbrush is native to the California coast, and named for San Francisco. 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 12-47" (30-120 cm) tall, grayish-green, becoming purplish with age. Leaves are 1-3" (3-8 cm) long, more or less lanceolate (lance-shaped), unlobed or lobed. Flowerheads are 2-16" (6-40 cm) in size, bright red to orange-red or yellow, appearing from March to May. The colored portions are really modified leaves (bracts). The flowers are ¾-1¼" (2-3.2 cm) long, yellow-green, cigar-shaped, and often much more prominent than those on other Castillejas. Fruits are ⅜-½" (1-1.5 cm) in size, with ¹/₁₆" (2 mm) seeds. They are found at low elevations near the coast.
