Cat Whiskers Facts

Cat’s Whiskers is botanically known as Orthosiphon aristatus and it belongs to the mint family.The genus name Orthosiphon comes from the Greek and means “upright tube.” This family is characterized by a square stem, volatile oils and decussate leaf arrangements; i.e. opposite pairs of leaves with each pair offset by 90 degrees to the previous pair. The plant owes its name to the four strikingly long stamens, which stick out, as long as a pen, looking like a cat’s whiskers sticking out from the white to pale purple flowers lip. The flowers are in spike-like flowery whorls, which is expressed by the epithet: Lat “aristatus” (= with ears). Only the leaves are edible and are widely used for herbal teas ( Java Tea ) in south-east Asia. Other plant parts are toxic! The flowers make an eye-catching display in gardens.
