'Caramel' Coral Bells (Heuchera villosa 'Caramel') is a real standout for variety in the garden by virtue of its caramel-color foliage with rust, red, and brown highlights. A great example of plant breeders' recent move to create primo foliage plants with Heuchera hybrids, 'Caramel' likes moist but well-drained, humusy soil. It thrives in summer heat and humidity, but will also grow in dry shade. It's said the plant rarely flowers, but with color like this, does it matter?
