A late Hello and welcome to you Rebekah!
You have gotten some excellent advice here.
I remembered a page that was listed a few years back about combinations of irises. On looking I think this is actually the one and it's about companion plants...but they (2 pages) have got such beautiful ideas for planning new gardens I though you and others might enjoy them.

While looking for the above pages I also ran across this page on the color terminology for irises. We had a lot of discussion about this about a year back so I thought some of the newer members might enjoy and appreciate the information.
