I have a somewhat sloped shady bed above my patio, edged by a low stone retaining wall. One end has a weeping red dissectum; I can't remember the variety, but it may be Red Dragon. I'm hoping it will eventually cascade over the wall. At the other end I wanted to put a green palmate for contrast, but learned there aren't many dwarf or weeping varieties. One I am considering is Jiro Shidare. I haven't actually seen one in person. Are there any other varieties I should consider?
