Orach
Atriplex hortensis
Zones 3–10
Growing
Orach is a remarkably hardy annual that serves as a robust, warm-weather alternative to spinach. Because it thrives in the cool season and can withstand light frost, you can begin sowing seeds once the soil has warmed. While it is quite adaptable to various light conditions, it performs exceptionally well in full sun or partial shade. When preparing your garden, aim for a well-drained site with a soil pH between 6.0 and 7.5 to ensure the plant develops its characteristic upright, branching stems.
As the plant matures, you may notice the foliage varies in color, with some varieties displaying vibrant red, white, or green leaves. The leaves themselves are somewhat thin and can have a slightly acidic taste. Since the plant does not ripen further once picked, you should harvest the leaves when they are at your preferred size and tenderness. To maintain the best quality, harvest the leaves ready to use and avoid letting them over-ripen or soften on the stalk.
For those growing in containers, orach is an excellent choice for small-space gardening. After harvesting, keep the leaves unwashed to help them maintain their freshness. If you cannot use your harvest immediately, you can store the leaves in the fridge or use them for freezing. Because the plant is wind-pollinated, it is a wonderful addition to a garden intended to attract pollinators.
