Cercis

The genus Cercis, commonly known as redbud, includes around ten species of deciduous trees and shrubs native to the temperate regions of the Northern Hemisphere – from North America through Southern Europe to Eastern Asia. All species share several distinctive traits: heart-shaped leaves reminiscent of the iconic symbol of love, and early spring flowering, when small blossoms appear directly on bare wood – on branches and trunks, before the leaves emerge. The flowers have the typical shape of legumes, as redbuds belong to the Fabaceae family. In gardens, the most cultivated species are Cercis canadensis (Eastern redbud), Cercis siliquastrum (Judas tree), and Cercis chinensis (Chinese redbud), each offering a wide range of cultivars with varying growth habits and foliage colours.

Eastern redbud originates from the eastern regions of North America – from southeastern Canada through the Great Lakes area down to Texas and Florida. The first botanical records of this species date back to the 16th century, when it was described by Spanish and French naturalists. In the 18th century, it reached European botanical gardens, quickly gaining popularity thanks to its early flowering and elegant form. Thomas Jefferson planted it in his gardens at Monticello, and George Washington recommended it for shrubbery plantings. In Native American culture, redbud had practical uses – its flowers were edible, and medicinal infusions were made from its bark. Today, it symbolizes spring and hope and has even become the official state tree of Oklahoma.

Description of the plant

CAROLINA SWEETHEART™ redbud is like fireworks glowing with several colours at once. This darling was developed in cooperation with the Star Roses and Plants Nursery by Thomas G. Ranney from North Carolina State University in the USA, who is also known in our country thanks to his of wonderful Storm™ series of quince.

It is a cross between varieties Forest Pansy with maroon leaves and Silver Cloud with silver variegated green leaves. The result is a fantastically coloured, deciduous shrub with broadly ovate to heart-shaped, matte leaves 6-10 cm across. Newly emerging leaves are a striking shade of pink in early spring, turning white with dark green centers. The transition between white and green is not sharp or mottled, more like sparkled. In summer dark green leaves take on a deep maroon tone in full sun and new leaves come out in a bright garnet red shade. From late summer new leaves and white margins on mature foliage gain vivid pink shades which last until autumn. In early spring, tiny, bright pink, pea-like flowers appear on miniature stalks on the bare wood.

It grows moderately (30-40 cm per year) into a broadly funnel-shaped shrub with slightly arching ends. You can grow it as a multi-stemmed shrub or a single-stemmed tree. Young branches tolerate trimming and pruning, but older plants dislike cutting into old wood which might result in fungi infection. CAROLINA SWEETHEART™ is protected by patent No. PP27712 from 2017.

Growing conditions and care

Eastern redbud is not particularly demanding when it comes to soil, it will thrive in ordinary garden soil as long as it’s well-drained. However, it performs best in slightly to strongly acidic soil with consistent moisture, though not in boggy conditions. During hot spells in June, we’ve observed occasional scorching of the youngest leaves on plants exposed to full sun without adequate watering. Fortunately, it has proven very resilient – damaged leaves were quickly replaced by new, healthy ones. Young plants benefit from protection against harsh spring sun, which can be surprisingly intense, and from drying winter winds, especially in exposed locations. It dislikes transplanting, this is a tree that settles into its spot and doesn’t appreciate being moved. It can be shaped by pruning while young; later, we recommend trimming only thin branches during dormancy, ideally in late winter before bud break. Its cold hardiness is excellent, commonly rated to -29 °C (USDA zone 5), with some sources suggesting it may survive down to -34 °C (zone 4a), though this remains untested. Container growing is not recommended as it needs space for its roots and a stable microclimate that pots cannot provide.
