CLARKIA

Native to western South and North America; especially numerous in California. Plants grow during cool times of year, bloom in spring and early summer. Attractive in mixed borders or in mass displays. Cut branches keep for several days; cut when top bud opens (others open successively). Sow seed in place in fall (in mild-winter areas) or spring. Seedlings are difficult to transplant, but volunteer seedlings grow well. Best in sandy soil without added fertilizer. Keep soil moist from seeding to flowering.

Clarkia concinna

California native. Grows to 1 1/2 ft. tall. Deep pink to lavender flowers with three-lobed, fan-shaped petals. Rounded leaves are 1/2–2 in. long. May be found in wildflower seed mixes.
