Cercis siliquastrum, commonly known as the Judas tree or Judas-tree, is a small deciduous tree from Southern Europe and Western Asia which is noted for its prolific display of deep pink flowers in spring. This species forms a small tree up to 12 m (39 ft) in height and 10 m (32 ft) in width. The deep pink flowers are produced on year-old or older growth, including the trunk, in spring. Also, the flowers display a blossom with five free petals and fused sepals. This flower shape is typical of the pea family (Fabaceae). The leaves appear shortly after the first flowers emerge. These are cordate with a blunt apex, which occasionally has a shallow notch at the tip. The tree produces long flat pods that hang vertically. The flowers are edible and purportedly have a sweet-acid taste. The species was first described by Linnaeus in 1753 and he gave it the specific epithet of siliquastrum which is derived from the Latin word siliqua, meaning 'pod'. The generic name comes from the Greek kerkis, a 'shuttle', which refers to the resemblance shown to this weaver's tool by the flat, woody seedpods. There are several varieties and subspecies including:- The flowers are pollinated by bees, attracted by nectar. Pollen from the protruding stamens is deposited on the bee's body and carried to another flower's stigma.
