Heuchera Indian Summer Series

Common name: Indian Summer Coral Bells, Indian Summer Heuchera

Description: The Indian Summer series showcases a collection of heat-tolerant heuchera cultivars specifically bred to maintain their vibrant foliage colours throughout the challenging summer months. These evergreen perennials form neat, rounded clumps of heart-shaped, lobed leaves that display exceptional colour intensity and stability. The series features varieties with rich autumn tones including warm oranges, deep reds, burnished coppers, and golden yellows that evoke the colours of Indian summer. Notable cultivars include 'Indian Summer Bronze' with bronze-orange foliage, 'Indian Summer Red' featuring deep burgundy-red leaves, and 'Indian Summer Gold' with bright golden-yellow foliage that maintains its intensity throughout the season. In late spring to early summer, delicate sprays of small, bell-shaped flowers appear on slender stems above the foliage. The series is particularly valued for superior heat tolerance and colour retention compared to many other heuchera varieties, making them excellent for challenging summer conditions.
