Phacelia tanacetifolia (Lacy Phacelia) is a fast-growing native annual prized as one of the single best bee-forage plants available, with lacy fern-like foliage and clusters of lavender-blue flowers.
Site Selection
Sunlight: Full sun.
Soil: Well-drained; adaptable to most soil types.
Planting Outdoors
Sow directly in fall or early spring. Scatter seeds and press lightly into the soil surface, covering no more than 1/8 inch. Space or thin to 6-12 inches apart. Keep soil lightly moist until germination (10-14 days).
Starting Seeds Indoors
Not typically necessary - Lacy Phacelia germinates quickly and easily from direct sowing, but can be started indoors 4-6 weeks before the last frost if desired.
Stratification & Scarification
Not required.
Watering
Water regularly during germination and establishment; moderate water needs thereafter.
Maintenance
Very low-maintenance; self-seeds readily. Often grown as a cover crop or pollinator strip.
Additional Notes
Native to the southwestern US (California, Arizona). One of the most attractive plants to bees of any native wildflower - highly recommended for pollinator gardens.
