About Chinese artichoke

Stachys affinis, also known as Chinese artichoke or gan lu zi, is a perennial plant from the Lamiaceae family valued for its edible tubers. It features oval leaves and characteristic square stems of mints, with pink or purple flowers in spikes. It is ideal for vegetable gardens or permaculture settings, where its attractive foliage and crunchy tubers make a great addition.

Care tips

It prefers full sun to partial shade and well-drained, organically rich soils. Keep the substrate consistently moist, especially during tuber development, but avoid waterlogging to prevent rot. A common mistake is planting it in heavy, clayey soils, which hinders tuber formation and harvest. Harvest tubers after the first frost for optimal flavor.
