Don't have many heucheras because it is so hot and dry in this area (Dallas). I rarely put in anything that needs more than a trickle of supplemental water. Had a couple of Green Spice that did very well for five years, until this last summer. Going to look for more later when we are out of the drought and maybe put them into full shade. Obsidian didn't like it here at all, only lasted a year. If you like chartreuse or lime colors, Pistache is still kicking after three years, but it is mostly in shade.
