The illustrated growing guide
Crimson Clover
Trifolium incarnatum
Family Fabaceae
Grown as an annual

The prettiest cover crop there is — a fall or spring sowing that fixes nitrogen, smothers weeds, and erupts into a breathtaking sheet of crimson flower spikes that bees and beneficial insects mob, before you turn it under to feed the soil. Sow it in bare beds over winter (mild zones) or before summer crops, and terminate at bloom. Beauty and soil-building in one packet.
