margins, meadows, and lightly disturbed sites. A graceful annual wildflower, it brings a delicate late-season display after many spring annuals have finished blooming. This species produces slender upright stems with sparse foliage and charming pink to lavender flowers. Each flower has four diamond-shaped to spoon-shaped petals, often dotted or marked with deeper pink, surrounding showy anthers with blue-gray pollen. Its airy form makes it beautiful tucked among native grasses, poppies, lupines, phacelias, and other annual wildflowers. Excellent for pollinator gardens, meadow plantings, woodland edges, and naturalistic California native plant gardens. Best sown in fall to early winter with the arrival of seasonal rains. Seeds may be surface sown or barely covered, as small Clarkia seeds should not be planted deeply. Prefers full sun to light part shade and well-drained soil. Once established, plants are fairly drought tolerant and bloom beautifully as the weather warms. Height: 1–3 feet. Optimum Soil Temperature for Germination: 55F–70F Blooming Period: April–June. Germination: 7–21 days Sowing Depth: Surface sow–1/16" Packet contains 80 organically grown seeds, untreated, non-gmo.
