Heuchera americana | Also known as: Coral bells | Rating: 0 votes | Print / Pdf

Heuchera americana is an herbaceous. Heart-shaped purplish leaves fade to green as they mature, and during summer, H. americana develops tall stems covered in soft white bell-shaped flowers. H. americana is best planted in full sun or partial shade and provided with well-drained soil that retains moisture. It’s, therefore most suited to shady areas where drying out can be avoided. H. americana is particularly good in herbaceous borders, rock gardens and even containers, where it makes a good contrast plant and will offer colour all year round.
