Which of the following is also known as Coral Bells?

Heuchera, commonly known as Coral Bells, is a perennial plant noted for its striking foliage and delicate flower spikes. The name "Coral Bells" comes from the small, bell-shaped flowers that emerge on slender stems, resembling coral formations. Heuchera is prized in horticulture for its diverse range of leaf colors, which include shades of green, purple, and silver, making it an attractive addition to gardens and landscapes.

In contrast, Astilbe is known for its feathery flower plumes and thrives in moist conditions, while Sedum is a succulent that is typically drought-resistant and often used in rock gardens. Salvia, known for its vibrant flowers and aromatic foliage, serves a different role in gardens, often attracting pollinators. Thus, Heuchera is clearly identified as Coral Bells due to its specific characteristics and common usage in gardening.
