Crimson Clover is a beautiful seasonal addition to a flowering lawn if you are okay with letting it grow at about one foot tall. Grows well in just about any type of well-drained soil, especially sandy loam. It is highly attractive to pollinators and fixates nitrogen to improve soil conditions and support the grass and other flowering plants in your lawn. Will not survive winter in zones 5 or colder but has the potential to reseed itself. What To Expect When Using Flawn Seed -- With regular watering, Crimson Clover will germinate in 1-2 weeks and plants will be small for the first couple of months. After the first growing season, it will bloom red flowers about 6-12" tall from May to June, creating a vital nectar and pollen source.
