Characteristics
Description
A perennial herb from the Asteraceae family native to Europe and Central Asia, growing 50-150cm tall. From mid to late summer, it produces small yellow flowers about 1cm in diameter in radiating dense clusters at branch tips. The leaves are deeply divided pinnate compound leaves, and the whole plant emits a strong fragrance. This scent contains camphor-like components with powerful insect-repelling effects, leading to its cultivation near windows in Europe since ancient times. The Japanese name 'wormwood chrysanthemum' derives from leaves resembling wormwood and chrysanthemum-like flowers.
