Heuchera 'Buttered Rum' – Warm Amber Foliage and Delicate Blooms for Year-Round Garden Interest
Heuchera 'Buttered Rum', commonly known as Coral Bells, is a striking evergreen perennial valued for its rich, warm-toned foliage in blends of amber, caramel, and burnished copper. Forming a neat, low-growing mound, it brings a distinctive warmth and depth to borders, containers, and shaded planting schemes throughout the year. In late spring to early summer, slender stems rise gracefully above the foliage, bearing delicate creamy-pink flowers that attract bees and other pollinators. Hardy, reliable, and beautifully coloured in every season, 'Buttered Rum' is an outstanding choice for gardeners seeking bold foliage impact with minimal effort.
Seasonal Beauty & Growth
Spring to Summer:
As temperatures rise in spring, Heuchera 'Buttered Rum' produces a fresh flush of glowing amber-copper leaves, forming tidy, rounded mounds with a warm, luminous quality. From late spring into early summer, slender upright stems emerge above the foliage, carrying airy sprays of soft creamy-pink flowers that add delicate height and movement while drawing in pollinators.
Autumn:
As the season cools, the foliage deepens to richer tones of burnt caramel and bronze, intensifying the plant's warm character and providing continued contrast and interest long after summer has passed.
Winter:
'Buttered Rum' remains evergreen through mild UK winters, retaining its amber and copper hues and continuing to provide structure and colour when much of the garden is bare. In colder or exposed areas, a light mulch around the crown will offer welcome protection.
Structure & Form
Heuchera 'Buttered Rum' has a low-growing, clump-forming habit, typically forming compact mounds of foliage with flower stems rising above in season. The rounded, lobed leaves are a warm blend of amber, caramel, toffee-bronze, and copper, often with attractive silver veining or overlay depending on light conditions. The upright flower stems add elegant vertical interest without overwhelming surrounding planting, making this variety equally well suited to small spaces and larger mixed schemes.
Perfect for Various Landscapes
🌿 Borders and Beds:
An excellent choice for edging borders or the front of mixed perennial beds, where its warm amber tones create striking contrast against green, silver, or deep purple foliage plants.
🌿 Containers and Pots:
Its compact, tidy form makes 'Buttered Rum' ideal for patio pots and mixed container displays, where its glowing colour adds warmth and structure throughout the seasons.
🌿 Ground Cover in Partial Shade:
When planted in groups, it creates a rich carpet of warm-toned foliage beneath deciduous trees or in lightly shaded areas, offering a natural and attractive ground-cover solution.
🌿 Wildlife Gardens:
The nectar-rich flowers are a valuable food source for bees, hoverflies, and other beneficial insects during spring and early summer, supporting garden biodiversity.
Growing Conditions & Care
Position:
Thrives in partial shade to full sun. Foliage colour is often most vibrant in dappled or partial shade, though it will tolerate more sun in cooler northern regions provided soil moisture is maintained. In deep shade, flowering may be reduced but foliage remains attractive.
Soil:
Prefers moist, well-drained, humus-rich soil with a slightly acidic to neutral pH. Avoid heavy, waterlogged conditions — improve drainage at planting time by incorporating compost or horticultural grit.
Watering:
Water regularly during dry spells, particularly in the first season after planting and when grown in containers. Once established, 'Buttered Rum' develops moderate drought tolerance, though consistent moisture encourages the best foliage display.
Maintenance:
Low maintenance: remove faded flower stems after blooming and tidy away any old or damaged leaves in early spring.
Every 3–4 years, lift and divide congested clumps in spring or early autumn to maintain vigour and encourage fresh growth.
Apply a light mulch of garden compost in spring to retain soil moisture and provide a gentle nutrient boost.
Winter Care:
Generally fully hardy throughout the UK. In colder or more exposed gardens, protect the crown with a dry mulch layer over winter to guard against prolonged frost.
