How to Grow Good King Henry

Chenopodium bonus-henricus

Perennial

Good King Henry is a hardy perennial vegetable native to Europe, once a cottage garden staple. It produces edible leaves (used like spinach), young shoots (cooked like asparagus), and flower buds (eaten like broccoli). Plant in rich, moist soil in sun or part shade. Do not harvest in the first year; allow the plant to establish a strong root system. From year two, pick leaves and shoots from spring through summer, always leaving enough foliage for the plant to recover. Extremely low-maintenance and long-lived.

Care Requirements

Light

Sun or partial shade

Grows well in full sun or partial shade. In hot climates, afternoon shade helps prevent wilting. Tolerates dappled shade under deciduous trees.

Watering

Keep moist during growing season

Prefers consistently moist soil, especially during the harvest period from spring to summer. Mulch to retain moisture. Tolerates brief dry spells but leaf quality declines.

Fertilizing

Compost mulch in early spring

Apply a thick layer of compost or well-rotted manure around the crown in spring. A light balanced feed after the first harvest flush helps sustain leaf production through summer.

Pruning

Remove flower stems to extend harvest

Cut flower stems as they appear if you want to prolong leaf production. Allow some to flower if you want self-seeding. Cut all growth back in late autumn after dieback.
