OK -- first of all, Lucy is a master Irisian, and anything that she has to say is valuable. Dave is also a smarty!!!!
But -- when I want to create a clump as fast as possible, I plant three rhizomes with the *toes* facing each other -- therefore the *heel* is facing outward. This gives the increases room to develop on the side of the heel, which is the mother.
Hope this makes sense.
