I'm insane over the Iris I purchased from Schreiner's a couple of years ago. Some of the blooms are seven or eight inches across and people can't believe it when they see them. But I only have a few for lack of space. I have an area that is a 45 degree slope that is about 5 feet from top to bottom and ten feet wide but I am wondering if they will 'slide' because of the slope or possibly not stand up straight? Anyone else plant on a slope? I can't make tiers because of tree roots that are less than a foot underground - they are choking the hostas that are there. That's one reason I thought it might be good for Iris because the roots don't go that deep - I don't think!
Also - what's a good way to 'hide' the foliage once the TOO SHORT bloom season ends. Or isn't there anything that will work without detriment?
Thanks for any ideas.
