Good King Henry is a perennial vegetable with spinach-like leaves and edible shoots, historically valued as a spring green and potherb. It self-seeds readily and is a low-maintenance addition to permaculture systems.

Why grow it

Good King Henry produces edible shoots and leaves earlier in spring than many annual spinaches and greens, making it useful for extending the harvest season in cool climates. As a perennial, it requires less annual soil disturbance and replanting than spinach or chard, though its productivity typically declines after the third or fourth year. It tolerates partial shade better than most leafy greens and performs adequately in marginal soils, suiting it to less-managed areas of a permaculture plot.

Watch out for

While self-seeding can be convenient, seedlings may appear in unintended locations and benefit from occasional thinning to prevent overcrowding. Harvesting should begin conservatively in the first year to allow the plant to establish a strong root system, with heavier cropping deferred to subsequent years.
