Its scientific name is Trifolium incarnatum, it has a much deeper crimson pointed flower, and it is a nitrogen fixing machine. Sow in spring or late summer for fall as it does best in cooler weather. It grows fast. Mow or cut back before flowers ripen and seeds set. As a fall cover crop, it can remain in the ground over the winter and turned in the next spring. Crimson clover will thrive in sun or partial shade. It is often used as an annual cover crop between rows of vegetables and mowed. The flowers are a magnet for pollinators beneficial insects and can also be used in herbal tea.
