When you see a jar that says 'clover honey' this is the type of clover that allowed the bees to create the honey. Melilotus is one of the most popular plants for honey production in the world.
Yes, I agree, the Sweet Clovers may not be right for every backyard garden but they are good for bees and the bees are good for our food supply. Don't feel bad if you want to pull it out. If it's not a good fit for your garden the bees will understand; they are not all that fussy.
(That being said, Bidens is also a popular honeybee plant; beekeepers love that stuff, but that won't sway me; I pull that Bidens out!!)
Melilotus (either the white or the yellow) also has medicinal value as, after the plant produces flowers the plant will contain a blood thinner - which is why I started growing the plant. I allow the plant to grow in one corner of my yard and it's easy to control. My neighbor next door grows a grass lawn and there is no Melilotus from my yard growing into his lawn.
