Care Guide

Planting

Plant Red Ribbons in fall or late summer by sowing seeds directly where you want them to grow - they prefer full sun and fast-draining soil, so avoid clay-heavy spots. Space them close together rather than thinning seedlings, since crowding actually encourages more blooms. They'll tolerate our Bay Area winters down to 15°F, so fall planting gives them time to establish before spring flowering.

After Planting

Water very lightly after planting, then once established, you'll only need to water once a month maximum during summer - this is a genuinely low-water plant. The biggest mistake people make is overwatering or amending clay soil without improving drainage; if your soil is heavy, work in compost or sand before planting. This is an annual, so expect it to flower spring through summer and complete its life cycle by fall.
