Care Guide
Planting
Plant your Leafy Aster in full sun, which is essential for this mountain native to thrive in the Bay Area. Space plants about 2 feet apart since they grow to roughly 2 feet tall. Plant in fall or early spring to give the roots time to establish before summer heat.
After Planting
Water weekly during your plant's first summer to help it get established, then taper off as it develops a deeper root system. In year one, expect the plant to focus on root growth rather than robust flowering as it adjusts to your garden. This is a perennial that comes from high-elevation meadows, so it will slow down or go dormant in winter - this is normal and healthy.
