I have the cylindrical variety of Sans. Last year, it did grow an additional cylinder rather rapidly. I was wondering, short of the plant duplicating itself, just how are they propagated? I read the FAQs on propagating from "leaves" but I would hardly describe these spears as leaves,or are they? Since winter seems to be lingering here, I really need some projects to keep me from pruning outside stuff before the last historic freeze date! (This is my first and only sans and I am enjoying the eclectic appearance of it.) Thanks!
