Since this is my first big year for planting and buying irises (got my feet wet in 2013) - I have so much to look forward to.
Tom, from pictures, I can't quite see the resemblance of Scatterbrain to Patchwork Puzzle - but I'll look again.(correction - I do see the resemblance) My memory
has focussed on a kind of mustard yellow edging on P.P., with more of a purple/lavender on the falls, and the light red falls of Scatterbrain. I know that form is crucial to good
irises - but I'm all about color! I see what you mean about P.P. being more brightly colored. You nailed it. I like them both!
