Sunflower : Eastern Redbud
Small Flowering Tree
Cercis canadensis L. (eastern redbud) is a large deciduous shrub or small tree, native to eastern North America from Southern Ontario, Canada south to northern Florida and west to Texas
It typically grows to 6–9 m (20–30 ft) tall with a 8–10 m (26–33 ft) spread. It generally has a short, often twisted trunk and spreading branches. A 10-year-old tree will generally be around 5 m (16 ft) tall. The bark is dark in color, smooth, later scaly with ridges somewhat apparent, sometimes with maroon patches. The twigs are slender and zigzag, nearly black in color, spotted with lighter lenticels. The winter buds are tiny, rounded and dark red to chestnut in color. The leaves are alternate, simple, heart shaped with an entire margin, 7–12 cm (3-5 inches) long and wide, thin and papery, and may be slightly hairy below.
The flowers are showy, light to dark magenta pink in color, 1.5 cm (½ inch) long, appearing in clusters from Spring to early Summer, on bare stems before the leaves, sometimes on the trunk itself.
