Aloysia citriodora Palau


Also known as cedron or Indian verbena, it is a plant of the verbenaceae family native to South America. It is cultivated in the temperate zones of Europe as an ornamental plant and for its medicinal properties. Its leaves give off, when rubbed, an intense lemony and somewhat minty fragrance. They are used in sauces, dressings and marinades to give an aromatic citrus touch.

It is a deciduous shrub up to 3 meters high. Its leaves are lanceolate, with a smooth or very finely serrated edge, light green on the upper side and the underside marked by conspicuous oil glands. The flowers are small, pink, whitish or whitish-violet grouped in lax terminal panicles. Flowering is in summer.
