clover blooms over a period of 7 to 8 weeks and has a high density of bloom
(840 blooms per yard)... Ball clover is an excellent honey plant, and bees
show a strong preference for it over other true clovers.

Overall, ball clover appeared to have the most complete set of favorable attributes in this environment (i.e. yield, reseeding ability, grazing tolerance, and a growth season that extended into the summer).
