In my youth this was a popular hay crop. Great nitrogen fixer, and if mowed early an excellent hay. When blooming it is very attractive to bees. The major source of clover honey. It is much better as a hay crop than white sweet clover.

Found throughout much of North America, Yellow Sweet Clover is actually a native of Eurasia. It blooms with yellow spike-like stalks from late Spring to early Fall.

Common in waste places, fields and along roadsides, it is a favorite plant of bees and butterflies. The leaves and flowers have a very pleasant vanilla like fragrance and it makes a wonderful honey. They can actually be used as flavoring if you so wish.
