Redbud hazel
Disanthus cercidifolius
Disanthus cercidifolius is a slow-growing deciduous shrub (Hamamelidaceae) native to woodland habitats in Japan and central/eastern China, grown almost exclusively for its spectacular autumn display of red, purple, orange, and yellow heart-shaped foliage and its curious paired, dark-purple, spider-like autumn flowers. It holds the RHS Award of Garden Merit and earns its place as a focal-point specimen in a sheltered woodland or acid-soil border. The honest catch is uncompromising soil chemistry: as a strict calcifuge it slowly declines and dies in limey soil above roughly pH 6.0, it is drought-intolerant and notoriously difficult to establish, and it is one of the slowest-growing ornamental shrubs in cultivation - a decade or more for a worthwhile specimen.
