Good King Henry

Good King Henry serves as an excellent perennial vegetable for forest gardens and permaculture designs. This hardy plant thrives in partial shade under fruit trees, making it ideal for guild plantings. Its deep taproot helps break up compacted soil while mining nutrients from deeper layers. Functions as a dynamic accumulator and provides year-round greens with minimal maintenance once established.

Traditionally used as a pot herb and spring tonic, Good King Henry contains iron, calcium, and vitamins A and C. The leaves have mild laxative properties and were historically applied as poultices for wounds and inflammation. Seeds were used as a gentle purgative. The plant contains oxalic acid, so should be consumed in moderation by those with kidney issues.

Young shoots can be prepared like asparagus, while leaves are cooked similarly to spinach. Best harvested before flowering when leaves are tender. The triangular leaves can be sautéed, added to soups, or used in quiches. Flower buds are edible and can be steamed like broccoli. Seeds can be ground into flour or cooked as a grain substitute, though yields are small.

Native to European mountains, Good King Henry attracts beneficial insects when flowering. The plant supports various moth caterpillars and provides nectar for small pollinators. Its deep roots help prevent erosion on slopes. Tolerates poor soils and can grow in pH 5.5-8.0. Self-seeds readily but isn't invasive, creating sustainable colonies that provide wildlife habitat.

Perennial growing 40-80cm tall with triangular, arrow-shaped leaves that feel slightly mealy when young. Stems are grooved and often reddish. Produces tall spikes of small greenish flowers from May to September. Leaves resemble spinach but are more triangular with a distinctive wavy margin. The whole plant has a characteristic mealy coating, particularly on young growth.

Good King Henry has no applications in building or timber use. The plant produces only soft, herbaceous stems that die back annually to the perennial rootstock. These stems are too weak and short-lived for any structural purpose. The plant's value lies entirely in its food and medicinal uses rather than any construction applications.

Named 'Good King Henry' to distinguish it from poisonous 'Bad Henry' (Dog's Mercury). The plant was once so valued it was grown in cottage gardens across Europe for centuries. In Lincolnshire, England, it's called 'Mercury' or 'Markery.' The scientific name Chenopodium means 'goose foot' referring to the leaf shape. Medieval monks cultivated it extensively in monastery gardens.
