bobjax,
Well I'll give you two. I did some crosses with 'Mister Lucky' 1.3 rating and 'Gypsy Rose Lee' 1.0 rating and the results produced a seedling that was one of those plants that the dark green foliage stood out from a distance as being far above the others. I picked those two because in my garden the foliage tended to look really nice on a regular basis.
I got four clumps from that seedling and potted two clumps and planted two clumps in separate places in the garden to see how they do.
Edited to add:
I have had some plants get really rusty, and I cut the foliage down really low and the foliage came back and stayed clean for most of the rest of the season, I did treat it for rust when I cut it but don't remember exactly what I used. I have read you could do this once a year but it was recommended not to do it more often, they did not give a reason, but I assumed it would weaken the plant too much if done more than once a year.
