Overview
Nemophila spp. is a genus of about 11 species of low-growing annuals in the borage family Boraginaceae, native to western North America, with the greatest diversity in California. Plants form spreading or trailing mounds 4 to 12 inches (10 to 30 cm) high, with brittle, succulent stems and soft, lobed or divided green leaves. The bowl- to saucer-shaped flowers are about 0.5 to 1.5 inches (1 to 4 cm) across and held singly on slender stalks. Flower color centers on sky blue and white: N. menziesii, baby blue eyes, has clear blue petals with a pale center, while N. maculata, five spot, is white with a purple blotch at each petal tip, and other species add veining or speckling. Plants grow quickly in the cool, moist part of the year, flowering through spring and into early summer before fading as heat and dryness arrive. They self-seed freely where conditions suit and reappear the next season. The genus grows in sun or light shade and moist, well-drained soil, and is sown directly where it is to flower because the brittle seedlings resent transplanting.
Native Range
Nemophila spp. is native to western North America, ranging through California and neighboring states into Oregon, Mexico, and the southwestern United States. Plants grow on grassy slopes, woodland edges, and moist open ground that dries out in summer.Suggested Uses
Nemophila spp. is used in spring bedding, edging, containers, and window boxes, and scattered through wildflower and meadow plantings for its blue and white flowers. Its trailing habit suits hanging baskets and the front of cool-season borders.How to Identify

Care Guide
Nemophila spp. grows in full sun to light shade and moist, well-drained soil, growing strongly in the cool conditions of spring and autumn. Seed is sown directly where plants are to flower, in early spring or in autumn for mild climates, since the brittle seedlings transplant poorly. Steady moisture keeps plants flowering, while heat and drought bring an early end to the season. Plants need little feeding, and rich soil produces lank growth at the expense of flowers. Self-sown seedlings often return the following year. Slugs and aphids are the main pests of the soft growth.Pruning
Nemophila spp. needs no pruning as a soft annual. Shearing lightly after the first flush can prompt a little rebloom while moisture lasts. Plants are pulled and composted once they collapse in summer heat.Container Growing
