We are on a mission (my sisters' idea)...wanting to know which dayliles make the biggest clumps the FASTEST? My sister wants to mass produce some daylilies...she heard the tubers can be used like water chestnuts in stir frys, and she wants to grow for that purpose. She doesn't care what type of daylily, as long as it is a very fast grower...I was thinking maybe older spider dips...but...dont really know...any suggestions?
