Common problems
Overwatering can cause root rot, and poor drainage may lead to fungal issues. Inadequate sunlight can reduce flowering. Occasionally, slugs or snails may nibble on the leaves.
Uses
Primarily grown as an ornamental plant for garden borders, rock gardens, and naturalized areas due to its attractive flowers and foliage.
