This is from eight inches to two feet high, with hairy, soft, dull green leaves and hairy stems, which are usually branching and spreading. The flowers are less than half an inch across, with a very hairy, sticky calyx, a violet corolla, varying in tint from dull white to bright blue, fading to purple, and purple filaments with whitish anthers. This grows in dry places and is common, often forming large clumps covered with flowers which are quite effective in color, though the plants are toe straggling and hairy to be very attractive close by. P, ramosissima is similar but coarser, the flowers are larger, and the plant is exceedingly hairy, the calyxes being covered with conspicuous, long, white hairs, and the whole plant unpleasant to touch.
