Halesia Carolina, also known as Carolina Silverbell is a small deciduous flowering tree or spreading shrub with magnificent snowbell flowers between March and May.
In early spring Carolina Silverbell shoots new large leaves measuring 16cms in length. The leaves are mid-green, shaped ovate to elliptic and make the perfect background to its snow-white bell-shaped flowers with bright yellow centres that appear just before the foliage breaks through. On mature specimens the clusters of snowdrop flowers hang in profusion from many branches nodding their bells in the breeze. The blooms, which measure 2cms in diameter, have a delicate, sweet scent. Flowers last until May before ripening into four winged seeds that remain on the branches into winter, long after the beautiful buttery yellow foliage has fallen with the frosts of late autumn. Seeds emerge green but develop a brown papery texture as they mature.
In winter the branches on both tree and shrub versions boldly stand out with their dangling collection of seeds.
