The purpose of the buckwheat is to keep the weeds at bay. It sprouts quickly, has decent sized leaves right away, and thus shades out the weeds. If it flowers, that would be great for the honeybees.
It doesn't fix nitrogen, and doesn't tolerate frost at all, so I don't have to worry about it being a nuisance next spring. I'll leave the dead plants on the beds and cover them with compost.
