The genus name Cercis comes from the ancient Greek word “kerkis” (κερκίς), meaning “weaver’s shuttle,” a reference to the shape of the plant’s seed pods. The species name siliquastrum refers to its elongated pod-like fruits (siliqua). The tree is also commonly known as the Judas tree, based on a Western Christian tradition that Judas Iscariot hanged himself on this tree after betraying Christ. However, the more widely accepted explanation is that the name derives from a French term, Arbre de Judée (“Tree of Judea”), referring to its native occurrence in that historical region of the Middle East.

Judas tree is a deciduous tree belonging to the family Fabaceae. It is native to the Eastern Mediterranean and naturally occurs in parts of Western Asia and Southern Europe, including Greece, where it grows in scrublands, forest edges and rocky slopes.

It typically reaches a height of 4–10 meters and forms a relatively irregular, rounded crown. The trunk is often twisted or multi-stemmed, especially in wild specimens. The leaves are simple, heart-shaped (cordate), with a smooth surface and bright green color.

Flowering takes place in early spring, before leaf emergence. The flowers are distinctive, ranging from pink to purplish, and emerge directly on the branches and trunk, creating a striking visual effect. The fruits are elongated, flattened pods that remain on the tree for a long period.

Judas tree thrives in Mediterranean climates and prefers sunny locations. It grows in a wide range of soils, including dry and calcareous ones, provided drainage is good. It shows high drought tolerance and adapts well to warm conditions.

Propagation is mainly by seed, although germination often requires pre-treatment, as well as by cuttings in cultivated forms. The species is generally resistant to pests and diseases.

It is primarily used as an ornamental tree due to its spectacular spring flowering. It also contributes to landscape structure and is widely used in Mediterranean-style garden plantings.
