  • Posted by ILPARW (southeast Pennsylvania - Zone 6b) on Mar 7, 2018 9:02 PM concerning plant:
    This cultivar has bluish-green foliage and is a bushy plant with fine-textured blades and large airy panicle flower clusters. It grows about 5 to 7 feet high. It is sort of cloud-like and in time it falls over some. I have cut it back some when it falls over with hand shears.
