American wildflower is perfect in beds and containers or as an annual groundcover.
This versatile native American wildflower (also known as California Blue Bells) is perfect in beds and containers or as an annual groundcover. Growing only 6" tall with a spread to 12", nemophila often overwinters in mild climates (zone 7 and above), where it blooms in early spring. Farther north, it flowers from early to midsummer. Grows best in partial shade. Must be kept moist if grown in full sun.
Sow outdoors in spring in a partially shaded to sunny area after chance of all frost, or in
late summer in frost-free areas. Sow seeds evenly and thinly and cover with 1/4" of fine soil
in rows 1' apart. Firm lightly; keep evenly moist. Seedlings emerge in 10-21 days depending on
soil and weather conditions. For earlier bloom, Sow seed indoors in individual pots, 6-8 weeks
before outdoor planting time.
How to Grow Nemophila
Nemphila thrives where summers are cool and nighttime temperatures keep below 65 F. Plants Sown
in the fall in southern areas bloom in late winter. In northern states, plants will bloom from
July to frost. Plant outdoors after last frost, in full sun to part shade. Site where there is
afternoon shade, where summers are hot. Water regularly and mulch to keep soil cool. Plants are
sensitive to moving and may be killed by extreme heat or humidity. Space to 1' apart.
