Care Guide
Planting
Plant California Phacelia in full sun with well-draining, sandy or gravelly soil - it's adaptable but won't tolerate soggy conditions. Space plants to accommodate their sprawling habit (they can reach up to 3 feet across). Plant in spring to give the plant time to establish before summer. This native perennial is deer resistant and works well in coastal gardens, chaparral-style landscapes, and naturalized areas.
After Planting
Water regularly during the first growing season to establish a strong root system, then stop irrigating once established - this plant is drought-tolerant and needs no summer water in the Bay Area. Expect flowers from spring through summer on mature plants. Year one, your phacelia will be focused on root development rather than bloom, so don't be discouraged if flowering is sparse. The biggest mistake gardeners make is overwatering; once established, extra water actually harms the plant, so resist the urge to help it along.
