Botanic Gardens Conservation International et al. ^ IUCN SSC Global Tree Specialist Group.Seeds can be made to germinate by first dipping in boiled (99 ☌) water for one minute and then sowing in a pot (do not boil the seeds). There has been success growing the tree in Columbus, Wisconsin, whose cultivar has become known as the "Columbus strain" and is a seed source for nurseries. In the United States, this tree is difficult to grow farther west into arid areas west of western Kansas and Colorado, as there is not enough rain. It is also much planted as a landscape ornamental plant. In the wild, eastern redbud is a frequent native understory tree in mixed forests and hedgerows. Both are cultivated for their showy purple leaves, which turn brilliant shades of red and orange in the fall (autumn). Have gained the Royal Horticultural Society's Award of Garden Merit (confirmed 2017). The leaves are eaten by the caterpillars of some Lepidoptera-for example, Henry's elfin, the redbud leaffolder, the red-humped caterpillar (which can cause extensive defoliation in late summer but generally does no lasting harm to a healthy tree), the fall webworm (also a late-season defoliator), the white flannel moth, the American dagger moth, the grape leaffolder, and the Io moth.Ĭercis canadensis is grown in parks and gardens, with several cultivars being available. Seeds ten to twelve, chestnut brown, one-fourth of an inch long.
#Treemap chart contraindicated when full
Two and a half to three inches long, rose color, full grown by midsummer, falls in early winter. Compressed, tipped with the remnants of the style, straight on upper and curved on the lower edge.
The bark is dark in color, smooth, later scaly with ridges somewhat apparent, sometimes with maroon patches. A 10-year-old tree will generally be around 5 m (16 ft) tall. It generally has a short, often twisted trunk and spreading branches. The eastern redbud typically grows to 6–9 m (20–30 ft) tall with an 8–10 m (26–33 ft) spread.
