I may have to go look. I had separated and replanted rhubarb last fall, and one big plant I divided and had a big root available to give my friend, and noticed it had started sprouting. But I mulched everything with seaweed in October so haven't seen if anything is emerging.
Edit: nope, nothing. But the worms are actively working on the seaweed so at least the garden is healthy. I moved my favorite very red rhubarb to a better place, better soil, and transplanted the one that grows two foot leaves into the original sandy spot. So we'll see.
