Orache (Atriplex hortensis), also called mountain spinach or French spinach, is a tall, handsome annual with broad, triangular leaves in colors ranging from pale green to deep burgundy-purple. Cultivated since ancient times as a spinach substitute, orache was one of the most popular potherbs in medieval European gardens before being displaced by true spinach. Its mild, slightly salty flavor and remarkable heat tolerance — it grows happily through the hottest summer months when spinach has long since bolted — have earned it a permanent place in the kitchen gardens of those who know it.
• Known as "mountain spinach" for its tolerance of cool, high-altitude conditions
• Also called "French spinach" because it remained popular in France long after other countries abandoned it
• Leaves come in green, red, and purple varieties — the red form is stunning in the garden
• Was one of the most common vegetables in medieval Europe before spinach replaced it
• The genus name "Atriplex" is an ancient Latin name for orache
• Exceptionally heat-tolerant for a leafy green, thriving in midsummer heat
Taxonomie
• Wild forms occur from Central Asia through Siberia to eastern Europe
• Has been cultivated as a vegetable since at least the Roman era
• Was a standard crop in medieval monastery gardens across Europe
• Gerard's Herbal (1597) lists several varieties including red and white forms
• Remained popular in French cuisine, where it was called "arroche"
• Used extensively in traditional Eastern European and Russian cooking
• Also cultivated in the Himalayan region as a leaf vegetable
• Has naturalized in many temperate regions
• First described by Linnaeus in 1753
• Experiencing a revival among permaculture and heirloom vegetable enthusiasts
• The red-leafed form is sometimes grown as an ornamental
Leaves:
• Broadly triangular to hastate (arrow-shaped), 5 to 20 cm long and 4 to 15 cm wide
• Thin, tender, with a powdery white or silvery coating on the surface
• Colors range from pale green to deep red-purple depending on variety
• Mild, slightly salty flavor when cooked
• Lower leaves larger, upper leaves progressively smaller
• Prominent veining
Stems:
• Erect, stout, branching, 60 to 200 cm tall
• Green to reddish-purple, matching the leaf color
• Smooth, slightly mealy
Flowers:
• Small, greenish, borne in dense spikes at the top of the plant
• Inconspicuous, wind-pollinated
• Male and female flowers on the same plant
Seeds:
• Small, enclosed in papery bracts
• Produced prolifically
• Exceptionally tolerant of heat, growing well at 20 to 35°C
• Also cold-tolerant, surviving temperatures to -5°C
• Adapts to a wide range of soil types, including saline and alkaline soils
• pH range from 6.0 to 8.5 — tolerant of alkaline conditions
• Prefers full sun to light shade
• Drought-tolerant once established
• Fast-growing, reaching harvestable size in 30 to 45 days
• Self-seeds prolifically
• Salt-tolerant due to specialized bladder cells on the leaf surface
• Relatively pest-free
• Bolts in long-day conditions but tolerates heat better than spinach
• Good source of vitamins A and C
• Contains moderate amounts of B-vitamins, particularly folate
• Provides iron, calcium, and potassium
• Naturally slightly salty due to mineral accumulation in the leaves
• Good source of dietary fiber
• Low in calories, approximately 20 to 30 kcal per 100 g
• Contains antioxidants and flavonoids, especially in red-leaved varieties
• Nutritional profile similar to spinach but with more minerals due to salt tolerance
• The silvery leaf coating contains concentrated minerals
• Direct-sow seeds in spring after last frost, or in autumn in mild climates
• Soak seeds for a few hours before sowing to improve germination
• Sow 1 cm deep, thin to 15 to 25 cm apart
• Germination in 7 to 14 days
• Can be broadcast for baby leaf production
• Harvest outer leaves as needed, or cut the entire plant 10 cm above ground for regrowth
• First harvest 30 to 40 days after sowing
• Keep soil moderately moist
• Tolerates poor soils but responds well to compost
• Succession sow every 3 weeks for continuous supply
• Self-seeds readily for volunteer crops in subsequent years
• Used as a spinach substitute in any recipe calling for spinach
• Sautéed with garlic and olive oil as a simple side dish
• Added to quiches, frittatas, and savory tarts

Wusstest du schon?
Orache was once so common in English cuisine that the word "orach" was used as a generic term for any potherb — Shakespeare's contemporaries would have been mystified by the modern concept of "spinach" because for them, orache was the default leafy green. The plant is making a quiet comeback in high-end restaurants, where chefs value its heat tolerance and striking red-purple leaves, proving that some medieval vegetables were ahead of their time.
