Houttuynia cordata ‘Chameleon’ (Harlequin plant) - Marginal pond plant - MP044

Houttuynia cordata 'Chameleon', commonly known as the Harlequin Plant or Chameleon Plant, is an ornamental, fast-growing perennial celebrated for its striking, multicoloured foliage. This cultivar is a vibrant and eye-catching variety of the Chameleon Plant, known for its variegated leaves that shift in colour throughout the seasons.

Description

Houttuynia cordata 'Chameleon' typically grows to a height of 30–45 cm (12–18 inches), with a spreading habit that forms dense mats of heart-shaped leaves. The leaves are highly decorative, showcasing a range of colours, from green in the centre to various shades of red, yellow, and orange on the edges. This colour shift, especially in cooler weather, gives the plant its "chameleon" effect, providing interest and vibrant contrast throughout the growing season. In late spring to early summer, it produces small, white flowers with four white bracts, adding subtle charm to its ornamental display. While the flowers are small and less significant than the foliage, they complement the overall appearance.

Growing Conditions

Houttuynia cordata 'Chameleon' thrives in full sun to partial shade and prefers moist, fertile soils. It grows well in consistently wet or waterlogged conditions, making it suitable for planting along pond edges, in bog gardens, or in containers with water trays. It can tolerate shallow water up to 5 cm (2 inches) deep. Hardy in UK conditions, it is frost-tolerant, though it may die back in winter and regrow in spring, offering an evergreen-like appearance in temperate climates.

Propagation and Care

Propagation is generally done through division of rhizomes in early spring or autumn. Like other Houttuynia varieties, 'Chameleon' spreads vigorously by rhizomes and can become invasive if not managed. It is best grown in containers or with physical barriers to control its spread in smaller gardens. Regular thinning and care are necessary to maintain its size and prevent it from overtaking other plants.

Uses

In addition to its ornamental qualities, Houttuynia cordata 'Chameleon' has culinary uses, particularly in Asian cuisine, where its leaves are used in salads and herbal teas, though it has a distinctive, strong aroma that might not be to everyone's taste. The plant also has medicinal properties, although it should be used cautiously due to its potency.

Ecological Value

Houttuynia cordata 'Chameleon' provides ecological benefits by stabilising soil along wetland margins and helping to reduce erosion. It also serves as ground cover in damp environments, providing habitat for small creatures and attracting pollinators such as bees. Its rapid growth helps maintain moisture in soil and improves the overall health of wetland ecosystems.

Considerations

While Houttuynia cordata 'Chameleon' is a vibrant and attractive plant, its vigorous growth can make it invasive in suitable environments. Gardeners should take care to manage its spread by growing it in containers or using barriers to prevent it from overwhelming other plants.

With its stunning, ever-changing foliage and ability to thrive in wetland conditions, Houttuynia cordata 'Chameleon' is a perfect addition to water gardens, bog gardens, or damp, shady areas. Its colourful leaves, ecological benefits, and vibrant seasonal shifts make it a standout in naturalistic garden designs, though careful management is recommended for smaller spaces.
