So I go with Hew-ker-ah, because of the genus name Heuchera.
This is Heuchera villosa 'Caramel', one of several new
Some day, I'll post pictures of all of them - 'Autumn Bride', 'Mocha', 'Citronella'.
Heuchera villosa is a native plant and someone or someone(s) are doing a great job of breeding new colors into it.
'Caramel' is my favorite.
(I also like chocolate covered caramels, but that has nothing to do with why I like this plant. It's all about the leaf colors on this one!)
