Safety & Hazards

Plants can contain quite high levels of oxalic acid, which is what gives the leaves of many members of this genus an acid-lemon flavour. Perfectly alright in small quantities, the leaves should not be eaten in large amounts since the oxalic acid can lock-up other nutrients in the food, especially calcium, thus causing mineral deficiencies. The oxalic acid content will be reduced if the plant is cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[1].

Cultivation Details

HabitAnnual/Biennial
Growth—

Species in this genus generally succeed in a variety of soils, but they prefer deep fertile moderately heavy soils that are humus-rich, moisture-retentive and also well-drained, with a position in full-sun or part shade[2]. Plants are usually annual, but, rarely, they can be biennial[3]. This is an extremely variable species represented in N. Africa, Asia, and Europe by several quite distinct races, recognized taxonomically mostly as subspecies[3]. It is closely related to Rumex pulcher[4]. Being wind -pollinated, Rumex species usually hybridize readily, especially with other members of the genus they are more closely related to[5].

Propagation

Seed - sow spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Rumex+dentatus>
