Worldwide, chiefly in northern temperate regions, sometimes cultivated. In South-East Asia wild plants are mostly escapes from cultivation.
The sour leaves and petioles are eaten raw or cooked as a vegetable, but their use is not very popular in South-East Asia.
- Annual (R. vesicarius) or perennial, mostly very variable herbs, sometimes more than 2 m tall (R. sagittatus).
- Leaves spirally arranged, the lower ones mostly in a radical rosette (except R. vesicarius), sheathing at base and provided with an amplexicaul ocrea.
- Flowers in spurious whorls which are combined in racemes or panicles.
- Fruit usually a sharply trigonous samara.
Can be cultivated in the tropics at higher altitudes in fertile soil. For good leaf production, the inflorescences should be removed.
