Answer: It sounds as though your plant might be in the wrong place, or it might not like the soil. Coral Bells grow best in morning sun or filtered afternoon sun (hot sunshine can burn the leaves), in average to rich soil. The need to be watered regularly for best growth. If your plant has just stalled, you might want to dig it up, amend the soil with organic matter, then replant and water it well. This should help your plant put down additional roots, which will result in more above-ground growth.
Best wishes with your garden.
