Castilleja integra A. Gray
Foothill paintbrush, wholeleaf Indian paintbrush, squawfeather
Wholeleaf Indian paintbrush (so named, presumably, to distinguish it from splitleaf Indian paintbrush) is a North American native, one of about 200 species of Castilleja. 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 up to 20" (50 cm) in height, covered with fuzzy white hairs. Leaves are linear, long and narrow, hairless on top and hairy beneath, often curled and almost tubular in shape. The leaves are entire, that is, not divided into lobes or forks as they often are with other Indian paintbrushes. Flowers are greenish in color, with a bright scarlet tinge; but they are largely hidden by the bracts, specialized leaves that are red-orange or sometimes yellowish in color.
