Cover crops can be planted in spring, summer or fall! Remember that ¼ to ⅓ of your growing area should be planted to green manure cover crops every year. This ensures your soil stays healthy and productive.

Seeds will store for at least 1 to 2 years.


Known as both Purple Tansy and Phacelia, this herbaceous species is a member of the borage family and is native to North America. It is considered an amazing superfood for bees and other pollinators, producing abundant nectar-rich flowers that attract insects from miles away.

A top choice for many gardeners and small-acreage growers. The plants look gorgeous in a landscape, and the flowers can be cut and bundled into beautiful bouquets.
Phacelia is a fast-growing species that is tolerant of dry and poor soils. It quickly forms a cover, providing soil protection that helps prevent erosion.

Often seeded as a mass planting or mixed with other cover crop species. Can be planted every 2 to 3 weeks in succession for an extended flowering period all spring and summer.

In fall or after tillage, the plant foliage breaks down relatively quickly, providing food for soil organisms and cycling back into the soil as organic matter.

Seeds germinate best in cool soil, and seedlings are tolerant of light frosts. Mature plants usually winterkill in the fall when temperatures fall to -8 degrees Celsius. If left to grow for the entire season, plants will often self-seed.
