How to Grow: Plant coral bells in slightly moist but very well-drained, loamy to humus-rich, well-aerated soil in moderate sun to part shade. Open shade or filtered sunlight in summer work well to keep plants cool and reblooming. With the exception of H. Americana, most coral bells do not tolerate full shade, and the purple, yellow, and variegated leaved hybrids appear to perform best in more sun. Transplant coral bells in August or early September.
If the woody crown grows too far above the ground you can dig them up, divide the rosettes, and bury them deeper in freshly prepared soil or spread a layer of mulch or compost over the crowns in the spring. Coral bells will not tolerate heavy soil or wet conditions and also tend to prefer a slightly acidic pH. If planted too deeply the crowns will be especially prone to rot in wet conditions so it is better to plant the crowns a little above the soil and avoid wet areas altogether. Good luck.
