Cercis canadensis 'Red Force' – Common Name: Redbud – A Striking Small Tree with Rich Purple Foliage and Dazzling Spring Flowers
Cercis canadensis ‘Red Force’, commonly known as Redbud, is a stunning small deciduous tree admired for its dramatic foliage and spectacular spring display. Originating from North America, this superb cultivar combines vivid early flowers with deep burgundy-purple, heart-shaped leaves that hold their colour throughout the growing season. As the year progresses, the foliage matures to a rich, warm tone and often takes on golden hues in autumn, ensuring year-round interest. Compact and elegant, ‘Red Force’ is perfect as a feature tree, in courtyard gardens, or even trained as a pleached form for architectural impact.
Why Plant
Cercis canadensis ‘Red Force’ (Redbud)?
Brilliant Spring Flowers – One of the most captivating features of ‘Red Force’ is its early spring display. Before any leaves appear, clusters of vivid pink, pea-like blossoms emerge directly from the bare branches and trunk, creating a unique and striking effect. The flowers are a welcome burst of colour at a time when most trees are still dormant.
Vibrant, Long-Lasting Foliage – After flowering, the tree produces large, heart-shaped leaves in a rich burgundy-purple shade that remains strong all summer. The foliage has a beautiful sheen and appears to glow when sunlight filters through it, adding depth and texture to borders or paved courtyards. As autumn arrives, the leaves take on tones of orange, bronze, or gold, extending its visual appeal into the cooler months.
Compact and Architectural Form – With its naturally rounded crown and manageable size, ‘Red Force’ is ideal for smaller gardens or more structured designs. Its graceful form makes it an excellent choice as a specimen tree, and it adapts beautifully to pleaching, where its elegant framework can define paths or create living screens.
Multi-Season Interest – Few trees offer such consistent appeal from one season to the next. ‘Red Force’ delights with pink spring flowers, summer colour from its glossy purple leaves, and warm autumn tones — even the bare winter branches add structure and charm.
Low Maintenance and Hardy – Despite its exotic appearance, ‘Red Force’ is hardy to around –15 °C (RHS H5) and thrives in most parts of the UK. Once established, it requires little attention beyond occasional watering and light pruning, making it an easy and rewarding addition to any landscape.
Wildlife Friendly – The spring flowers attract bees and early pollinators, while the branching habit provides perching spots and light shelter for birds.
How to Grow
Cercis canadensis ‘Red Force’ (Redbud)
Soil – Prefers fertile, moist but well-drained soil. It grows well in loam, clay, or sandy soils that are neutral to slightly alkaline. Avoid waterlogged ground, especially in winter. Adding organic matter at planting time will improve establishment and long-term health.
Light – Best in full sun to partial shade. Full sun enhances the depth of the foliage colour and promotes abundant flowering. In warmer or more exposed sites, a little afternoon shade can help prevent leaf scorch.
Watering – Keep well-watered during the first couple of growing seasons, particularly in dry weather. Once established, it is moderately drought tolerant but benefits from consistent moisture. Mulching annually helps to conserve moisture and maintain soil quality.
Pruning – Minimal pruning is needed. If required, remove any crossing or damaged branches after flowering in late spring or early summer. Avoid heavy pruning as this can spoil its natural shape. For pleached forms, trim lightly each year to maintain the flat framework.
Fertilising – A balanced slow-release fertiliser applied in spring will support strong growth and foliage colour. Overfeeding should be avoided, as excessive nitrogen can reduce the intensity of the leaf colour.
Winter Care – Fully hardy across most of the UK. Young trees may benefit from a mulch around the base to protect roots from frost. Avoid exposed, windy sites which may damage early spring blooms.
