I'm in zone 5b (Amherst OH) and I must say this is the only heuchera that's been able to stand our terribly hot & sunny summer this year. I had 4 heuchera in my full sun bed and Stormy Seas never showed wilt, sunburned leaves, nor "crisping", like the others did. SS has been in its present location for 3 years. I'm moving the others, but SS will stay put.
As far as heuchera go, it has smaller size leaves, but spreads quickly enough to make up for it. A true tough Heuch!

I just planted several of these in a new bed. Any suggestions for companion plants?

Ruffled foliage in shades of pewter, burgundy, and green. Can be planted in spring or fall. Grows to 18".

2 foot stalks bear tiny bell shaped flowers late spring, early summer. Nice form and quite hardy. Full sun or part shade and drought tolerant. Good under redwoods and native oaks.

The leaf design and color variations make this a striking plant to add to your low light garden spots. This year, however, due i am assuming, to the large quantity of rain in the Virginia area, the heuchera have died randomly due to what looks like a fungus. Difficult to save once the black, sooty appearance begins to damage the plant.
