I've only had a few Heuchera so far, but mostly they just seem to get smaller each year. The only one that hasn't (yet) is Palace Purple. I know they're sold everywhere now and pretty common, but I got 3 on clearance during last year's drought. This spring they look great, even growing in dry soil beneath a very competitive pine tree.

And as much as I've abused Christa by relocating it four times, it looks the same each year. Maybe it will grow if I stop digging it up.
