Phacelia campanularia A. Gray
Desert bells, Bluebells, Desert Canterbury bells
Hydrophyllaceae (Waterleaf Family)
USDA Symbol: PHCA3
An 8-16 in. annual with 1 in. wide, bell-shaped, deep-blue flowers. The flowers, with protruding golden anthers, are arranged in rolled, 1-sided racemes; the raceme unrolling as the flowers open. A stiff, erect, leafy, glandular-hairy plant with dark blue, bell-like flowers in loose coils at end of a branched open cluster. Leaves are round to oval; both they and the reddish stems are covered with fine hairs.
In a spring following a wet winter, thousands of these plants will bloom, forming masses of deep rich blue. The similar California Bells (P. minor), found in southern California and northern Baja California, has a violet corolla with a cream spot on each lobe, the opening slightly constricted, and hair on the expanded stamen bases.
