Care Guide
Planting
Plant your California Larkspur in full sun during spring, the plant's natural blooming season. This Bay Area native prefers the foothill woodland and mixed evergreen forest conditions it evolved in, so choose a spot that mimics those drier, well-draining slopes. Space plants to accommodate their impressive height - they'll reach 6 to 7 feet tall - and give them room to develop their long taproot system without competition.
After Planting
Water weekly during your plant's first summer to establish its deep root system, then taper off as it matures and relies on natural rainfall. California Larkspur is a moderate-care plant that's deer resistant, so you won't need to protect it from browsing. The biggest mistake gardeners make is overwatering in our mild Bay Area winters; this native wildflower expects drier conditions and will rot if kept too wet when dormant.
