Safety & Hazards

No member of this genus contains any toxins, all have more or less edible leaves. However, if grown with artificial fertilizers, they may concentrate harmful amounts of nitrates in their leaves. The seed contains saponins[1]. Although poisonous, saponins are poorly absorbed by the human body and so most pass through without harm. Saponins are quite bitter and can be found in many common foods such as some beans. They can be removed by carefully leaching the seed or flour in running water. Thorough cooking, and perhaps changing the cooking water once, will also normally remove most of them. However, it is not advisable to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish[PFAF].

Cultivation Details

HabitAnnual
GrowthFast

Orach thrives in any temperate climate. It is reported to tolerate an annual precipitation in the range 300 - 1,400mm, a mean average annual temperature in the range of 6 - 24°c[2]. Orach is a very easily grown plant, doing equally well in a wide variety of well-drained soils, though rich, moisture-retentive soils give the quick growth that is necessary for the production of tender leaves[3, 4, 5, 2]. Plants require a position in full sun and are tolerant of saline and very alkaline soils[5]. Tolerates a pH in the range 5.0 to 8.2[2]. Established plants are drought resistant[2]. Some forms of this species have bronze or deep red leaves and are occasionally grown as ornamental plants, their leaves taste the same as the green-leafed forms[PFAF]. Plants are fast-growing[6] and usually self-sow quite freely if the surrounding soil is disturbed by hoeing etc[PFAF]. They tolerate hot weather well, but soon go to seed so successive sowings at 4 weekly intervals are required during the growing season if a continuous supply of leaves is required[2]. Leaves can be harvested 40 - 60 days after sowing the seed[2].

Propagation

Seed - sow early spring to late summer in situ, only just covering the seed[7]. Germination is usually good and rapid[PFAF]. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-20. <temperate.theferns.info/plant/Atriplex+hortensis>
