Is there a dark Heuchera/ella/Tiarella for SE full sun?
I know there are some Heucheras, Heucherellas and Tiarellas that will tolerate or even like full sun. I am in central NC and I need a dark purple, black, burgundy, dark red foilage perennial to compliment Blue Princess Verbena (lavender flowers) and Glow Girl Spireas (bright lime foilage). Burgundy is the other color that is mixed into this border (along with buttery yellow, FYI). I thought about Eucomis Sparkling Burgundy and will probably still mix that one in a bit, but really, Heucheras (etc.) are the perfect plant b/c they have all the colors that I would want to blend in. Burgundy, Lime, Purple, etc. BUT will any of the darker varieties take sun from 10:00 am until about 4 pm? I have noticed that some varieties (like Solar Eclipse) say that they took 100 degree days, but then Lazy S still lists them as part sun in the South. Anyone had any success with full sun in the SouthEast on any of these? I know Obsidian has had great success, but what else?
