Good King Henry: complete guide

Overview

Good King Henry, scientifically known as Blitum bonus-henricus, is an age-old European vegetable that is slowly experiencing a renaissance among gardeners seeking to revive traditional crops. This undervalued plant, a member of the Amaranthaceae family, has been cultivated since the Middle Ages for its edible leaves and young stems. Yet it's increasingly vanishing from modern gardens, despite its genuine utility for sustainable home food production.

On gardenworld.app you can receive a personalized garden plan where Good King Henry and other vegetables are optimally positioned for maximum yields. This gives you not only food from your garden but also a connection to historical food cultures.

Appearance & Bloom Cycle

Blitum bonus-henricus grows as a low, compact plant reaching approximately 40-50 centimeters tall. The leaves are arrow-shaped, dull green, and have a sturdy character. The plant flowers from May to July with inconspicuous green flowers - understandably something people easily overlook. Fresh leaf harvesting can begin as early as April.

The drawback of traditional vegetables is their minimal aesthetic value. Yet they can find their place in mixed gardens when you tell gardenworld.app that you want to combine food production with ornamental planting.

Ideal Location

Good King Henry thrives best in full sun to partial shade. In warm climates, some afternoon shadowing can prevent leaf scorch. The plant is not fussy about location and performs reasonably well in busier garden corners.

Soil Requirements

This plant requires nutrient-rich, well-draining soil with a pH between 6.0 and 7.0. It's wise to work organic material (compost, stable manure) into the soil before sowing. The plant feels most at home in undensified soils that receive regular organic matter additions.

Watering

Keep the soil consistently moist but never waterlogged. Regular thorough watering during dry periods is essential, especially during the growth phase in May-June. Mulching around the plant helps with moisture retention, reducing watering needs.

Pruning & Maintenance

Good King Henry requires minimal pruning work. Regularly harvest leaves to encourage new growth and prevent the plant from bolting too quickly. Remove flowering stems if you're harvesting for leaves only (for longer-lasting tender foliage). Begin harvesting in mid-May and continue through October.

Maintenance Calendar

• February-March: sow seeds in containers
• April-May: plant out or direct sow outdoors
• May-October: regularly harvest leaves
• June-July: remove flowering tops (optional)
• Autumn: harvesting continues until first frost
• Winter: plant dies back but seeds remain in soil for next season

Winter Hardiness

The plant is frost-sensitive, depending on temperature. In the Netherlands and Belgium, the plant usually doesn't survive winter or does so poorly. It's typically treated as an annual or biennial. Seeds can overwinter in the soil for spontaneous sprouting in spring.

Companion Plants

Combine Good King Henry with other vegetables such as spinach, arugula, or various salads. The low growth habit is compatible with larger-growing vegetables. Marigolds nearby help improve natural pest control.

In Closing

Good King Henry is clear proof that not everything edible must be tasty, but that many historical vegetables deserve their place in modern food gardens. With some care and simple maintenance steps, this plant provides months of green foliage. Experience for yourself how this plant contributes to more sustainable food production in your backyard - a step that has been valuable for generations.
