Phacelia Seed (lb)

Phacelia tanacetifolia Annual cool season cover crop.

Phacelia is a non-legume, fast-growing broadleaf cover crop valued for its ability to improve soil fertility, suppress weeds, and support pollinators. Its fern-like foliage and striking blue flowers provide both function and beauty in the garden or field. Known for its excellent capacity to accumulate and recycle excess nitrates and calcium, phacelia enriches soil health while protecting against nutrient loss. Winter-killed at 20°F, it is well-suited for crop rotations in cool-season systems and can also be used for feed or hay in soils with low to medium nitrogen availability.

Quick to establish, phacelia germinates in just 5–10 days and thrives in a variety of soil types. Its dense growth shades out weeds, reduces erosion, and adds valuable organic matter when incorporated as green manure. The vibrant blooms are highly attractive to bees and beneficial insects, making it one of the best cover crops for supporting biodiversity and pollinator health. Easy to manage and non-invasive, phacelia is an excellent option for regenerative gardens, orchards, and small farms seeking to build long-term soil fertility.
