Where It Fits

Best Uses for Lacy Phacelia

Lacy Phacelia is unusually versatile, fitting into both ornamental wildflower plantings and agricultural pollinator or cover crop systems.

California Native Wildflower Mixes Adds a native annual with distinctive lavender-blue flowers and finely textured foliage.
Pollinator Plantings An excellent flowering species for increasing forage diversity for bees and other beneficial insects.
Vineyards & Orchards Can be incorporated into suitable flowering cover crop and beneficial-insect plantings between permanent crop rows.

Establishment & Management

Growing Lacy Phacelia

Lacy Phacelia establishes rapidly from seed and performs best where good seed-to-soil contact, adequate establishment moisture and reasonable soil drainage are available.

California Planting Window

Fall planting works particularly well in many Mediterranean-climate areas of California, allowing seasonal rainfall to support establishment and spring flowering.

Planting Depth

Seed shallowly. When drill-seeded, approximately 1/4 inch is an appropriate planting depth. Avoid placing the small seed excessively deep.

Soil & Drainage

Lacy Phacelia performs best on reasonably well-drained soils. Maintain adequate moisture during germination and early growth.

Reseeding Management

Allow flowers to mature and set seed where natural reseeding is desired. Terminate or mow before mature seed development where volunteers are not wanted.

Wildflower + Working Cover Crop

More Than Just a Pollinator Flower

Lacy Phacelia stands out because it can serve more than one purpose. Its lavender-blue flowers provide valuable pollinator habitat, while its fast annual growth and extensive root system make it useful in cover crop systems. This combination gives the species a strong fit in California native wildflower plantings, orchards, vineyards and diversified agricultural landscapes.
