Untreated Lilla Phacelia Cover Crop Seed

Improve Soil While Supporting Pollinators

Untreated Lilla Phacelia (Phacelia tanacetifolia) is a fast-growing, cool-season annual cover crop prized for its ability to improve soil health, attract beneficial insects, and suppress weeds. This versatile broadleaf plant produces soft, fern-like foliage and distinctive curling clusters of vibrant blue-violet flowers that provide an abundant source of nectar and pollen throughout the blooming season. As a result, it has become a favorite among farmers, gardeners, beekeepers, and regenerative agriculture practitioners seeking to build healthier soils while supporting local pollinator populations.

Build Healthier, More Productive Soil

As the plants establish, their vigorous root systems improve soil structure by increasing aeration and promoting better water infiltration. At the same time, the lush top growth produces abundant organic biomass that enriches the soil as it decomposes. Consequently, soils become more fertile, easier to work, and better able to retain moisture while supporting beneficial microbial activity.

Lilla Phacelia also serves as an excellent nitrogen catch crop. Its active root system captures residual soil nitrates that might otherwise leach away after harvest. In turn, valuable nutrients remain available for future crops, improving nutrient efficiency and reducing environmental losses.

Naturally Suppress Weeds

In addition to improving soil quality, this cover crop establishes quickly and forms a dense canopy that shades the soil surface. As a result, emerging weeds receive less sunlight and struggle to compete. Furthermore, reducing weed pressure helps minimize cultivation while creating a cleaner seedbed for the following crop.

Create a Haven for Pollinators

Throughout the flowering period, the striking blue-violet blooms attract large populations of honeybees, native bees, butterflies, hoverflies, and other beneficial insects. Moreover, many predatory insects that feed on common garden pests also visit the flowers, helping encourage a healthier and more balanced growing environment. Whether planted near vegetable gardens, orchards, vineyards, or flowering landscapes, Lilla Phacelia supports increased biodiversity and healthier pollinator populations.

Plant Characteristics

• Height: 2–4 feet
• Foliage: Soft, feathery, fern-like green leaves
• Flowers: Bright blue-violet, downward-curling flower clusters
• Seed Status: Untreated and natural, free of chemical coatings and synthetic fungicides

Agricultural & Garden Benefits

• Attracts honeybees, native bees, butterflies, and beneficial predatory insects.
• Scavenges residual nitrogen to reduce nutrient leaching.
• Establishes rapidly to suppress weeds naturally.
• Improves soil tilth by adding valuable organic matter.
• Encourages beneficial microbial activity and long-term soil health.
• Ideal for cover cropping, pollinator habitats, vegetable gardens, orchards, vineyards, and regenerative agriculture.

Sowing & Growing Information

Planting Depth – Cover seeds with 1/8–1/4 inch of soil. Because the seed requires darkness for optimal germination, ensure good seed-to-soil contact.

Soil Temperature – Germinates best in cool soils between 40°F and 68°F.

Seeding Rate

• Field Plantings: Approximately 7–12 lbs. per acre
• Small Plots: About 3 oz. per 1,000 sq. ft.

Management – Tolerates dry, low-fertility soils well after establishment. However, terminate the stand before heavy seed production if self-seeding is not desired.

Best Used For

• Cover crop plantings
• Pollinator habitats
• Vegetable gardens
• Orchards and vineyards
• Regenerative agriculture
• Soil improvement and erosion reduction

Untreated • Pollinator Friendly • Fast Growing • Soil Building • Non-GMO

Available in convenient package sizes for farms, market gardens, orchards, vineyards, and home gardeners looking to improve soil health while supporting pollinators and beneficial insects.
