What is the species name for this type of heuchera
http://tinyurl.com/ldkpzo

Found it. Coral Flower.

That would be a vernacular name. There were two other vernacular names
(alumroot and coral bells) given at the URL you cited.

The species name is Heuchera x brizoides, but there may be some doubt as
to its validity. (It's not listed in the International Plant Name Index,
and at least one web page gives it as Heuchera x brizoides hort.) The
RHS Plant Finder does not assign Bressingham Hybrids to a species.

It's said to be a complex hybrid, included H. sanguinea, and at least
some of H. americana, H. bracteata and H. micrantha.
