Cercis siliquastrum


Deciduous small tree, with heart shaped leaves and pink early spring flowers, present on older wood, often flowers are also grow on the main stem. Typically 8 to 12m tall at maturity. Native to south eastern Europe and western Asia. A member of the Fabaceae (legume, pea/bean) family, this tree is able to "fix" nitrogen (because of a symbiotic relationship with the bacteria Rhizobium) and store it in specialised root nodules. The tree gets its common name as it is reputed to be the tree from which Judas Iscariot hung himself. The bark is used in Chinese medicine as an antiseptic. Fossil evidence suggests this genus is at least ca.45 million years old.
