Care Guide
Planting
Plant your California Wildrose in full sun with moist, loamy soil - though it tolerates clay and different soil types, it performs best in well-draining loam. Space plants generously if you want them to grow into their full 3–6 feet tall and wide without pruning; they naturally form large thickets and make excellent hedges or barriers. Plant in spring or fall to give roots time to establish before summer heat.
After Planting
Water weekly during your first summer to get the plant established, then taper back to supplemental irrigation no more than 3 times per month once it's mature - California Wildrose is drought-tolerant but flowers better with consistent summer water in the Bay Area. Pruning is optional if you have space; if you need to manage its size, do light shaping in late winter or after flowering. Expect it to drop its leaves in fall and regrow in spring, and don't be alarmed by slow growth the first year - this is normal as the plant focuses energy on root establishment.
