Safety & Hazards

The leaves and seeds of all members of this genus are more or less edible. However, many of the species in this genus contain saponins, though usually in quantities too small to do any harm. are poorly absorbed by the body and most pass straight through without any problem. They are also broken down to a large extent in the cooking process. Saponins are found in many foods, such as some beans. 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]. The plants also contain some oxalic acid, which in large quantities can lock up some of the nutrients in the food. However, even considering this, they are very nutritious vegetables in reasonable quantities. Cooking the plants will reduce their content of oxalic acid. 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

HabitPerennial
Growth—

Prefers a fertile humus rich soil in a sunny position[2, 3, 4]. The plant produces a better quality harvest in the summer if it is grown in light shade[5, PFAF]. A very easily grown plant, it tolerates considerable neglect and succeeds in most soils and situations[3, 6, PFAF]. Good King Henry was at one time frequently cultivated in the garden as a perennial vegetable, but it has fallen out of favour and is seldom grown at present[7, 8]. About thirty plants can produce a good supply of food for four people[5].

Propagation

Seed - sow spring in a cold frame. Germination can be slow, but usually a high percentage will germinate[PFAF]. Prick out the seedlings into individual pots as soon as they are large enough to handle and plant out into their permanent positions in the summer. Division in spring[4]. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the summer or following spring. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-20. <temperate.theferns.info/plant/Chenopodium+bonus-henricus>
