Orach
Also known as: Mountain Spinach · Atriplex hortensis
3 types of orach
Aurora
45 daysMixed colors on one plant — magenta, pink, gold, and green leaves in the same seed packet. Ornamental and edible.
Green Orach
40 daysClassic pale-green arrow leaves — mildest flavor, closest to a true spinach substitute. Very productive.
Red Orach
40 daysDeep magenta-purple arrow-shaped leaves on a 5–6 ft plant. Turns cooking water beet-red. Stunning in salads.

How to plant
Direct-sow after frost — orach loves the summer heat that flattens spinach. Pinch flower stalks to keep the plant leafy; unpinched plants top 6 ft and drop thousands of self-sowing seeds. Young leaves for salads, mature leaves cooked like spinach.
Grower's tip
The best summer stand-in for spinach — mild, tender, and unfazed by 90°F days. Red orach glows almost neon in low sun and stains anything it touches pink.
Soil preferences
Rich, moisture-retentive loam.
6.0–7.0
Compost + a light nitrogen source (blood meal, aged manure) — greens are all leaf, so they want nitrogen.
Watering
Consistent — 1 in per week minimum, more in heat. Uneven water triggers bolt.
Overhead is fine in the morning; drip is best in humid climates.
Overwatered: soft rot at the crown, yellow lower leaves. Underwatered: bitter flavor, tough leaves, premature bolting.
Either works — Top-water is fine — greens enjoy a gentle morning overhead rinse to cool the crown. Bottom-water indoor seedlings and microgreen trays to prevent damping-off. Skip evening overhead water.
Temperature tolerance
55–75°F (13–24°C) — most greens bolt above 80°F (27°C)
45–60°F (7–16°C)
Light frost tolerated by most; kale, spinach, mâche, and collards are cold-hardy and often sweeter after frost.
Container growing
Yes — great in containers
6–8 in deep, any width; a window box works
Perfect for pots and hydroponics; cut-and-come-again mixes give weeks of harvest per sowing.
Succession planting
Every 2 weeks spring and fall. Skip the hottest weeks or use shade cloth.
Detailed harvesting
Cut outer leaves and let the crown keep producing (cut-and-come-again), or cut the whole rosette 1 in above the crown for a fresh flush.
Post-harvest storage & preservation
Rinse, spin dry, and store in a sealed bag with a paper towel in the crisper 5–7 days. Blanch and freeze for cooking greens.
Culinary, medicinal & other uses
Salads, sautés, smoothies, soups. Bitter or overgrown leaves are best cooked, not raw.
Medicinal or traditional uses are shared for interest only — this is not medical advice. Consult a qualified professional before using any plant medicinally.
Seed saving
Lettuce is self-pollinating; spinach is wind-pollinated; brassica greens (kale, arugula, mustard) are insect-pollinated and cross freely.
Lettuce 20 ft; spinach 1/2 mile; brassicas 1/4 mile or cage.
Let a robust plant bolt; harvest dry seed stalks; rub clean; store dry.
Your zone's planting calendar
Pick your USDA hardiness zone and we'll estimate the key dates for orach in your area. These are regional averages — always check your own last-frost forecast before sowing.
From your kitchen — grow orach from what you already have
Let one plant bolt (send up its flower stalk) and it will make hundreds to thousands of seeds. Bolted greens are bitter to eat but perfect for saving.
- 1Pick your best, slowest-to-bolt plant as the seed parent.
- 2Let the flower stalk rise, bloom, and dry brown on the plant.
- 3Cut the whole stalk into a paper bag before it shatters.
- 4Rub between your hands to release seed; sieve out chaff; store dry.
Storage: 3–5 years dry.
