Growing Patience Dock, Rumex patientia, aka Herb Patience, Spinach Dock, Monk’s Rhubarb, Is Easy In The UK, & It Is Becoming Popular. Here’s Why & How.

Why Should I Grow Patience Dock?

Patience Dock is eaten in countries such as Korea,, which is surprising in some senses as it originates from southern and eastern Europe. But when we realise it has now naturalised in Asia, North America and the rest of Europe perhaps the reason for it being eaten more widely becomes clearer. However, the traditional region for its consumption was the Balkans and nearby.

As for the Koreans, while not traditional mountain vegetable (sannamul), its tangy flavour and hardiness make it an excellent substitute for Korean wild greens like chwinamul (Aster scaber).

Growing Patience Dock: A Guide for British Gardens

Growing Patience Dock: Key Characteristics

  • Type: Perennial (lives 3–5 years).
  • Appearance: Large, lance-shaped leaves (up to 30cm long); tall flower spikes in summer.
  • HardinessFully hardy (survives UK winters, zones 4–8).
  • Flavour: Mildly sour/lemony (similar to sorrel), less bitter than common dock (Rumex obtusifolius). But eat it in moderation as it contains oxalic acid! It’s fine raw or cooked in moderation but just sample a small amount the first few times.

Sowing & Planting

  • When: Sow seeds March–April (outdoors) or August–September. Or just let it self seed!
  • Soil: Moist, fertile soil (pH 6.0–7.0). Tolerates clay but thrives with compost.
  • Sun: Full sun to partial shade.
  • Spacing: 30–40cm apart (grows in clumps).

Care & Maintenance

  • Watering: Keep soil moist (drought causes bitterness).
  • Feeding: Not essential, but you could apply liquid feeds eg. seaweed, monthly for tender leaves.
  • Pests: Generally resistant. Watch for leaf miners (remove affected leaves).
  • Harvesting:
    • Spring/Summer: Pick young leaves (under 15cm) for best flavour.
    • Method: Cut outer leaves, leaving the crown to regrow.
    • Yield: One plant provides ~500g leaves per season.

Overwintering

  • Dies back in winter; regrows from roots in spring.
  • Protection: Mulch with straw or leaf debris in harsher winters.

Flavour Profile

  • Raw: Crisp, citrusy (use sparingly in salads). See preparation below.
  • Cooked: Mellow sourness; similar to spinach-sorrel hybrid.
  1. Blanch leaves for 1–2 minutes in boiling water.
  2. Drain, rinse in cold water, and squeeze dry.
  3. Chop finely for recipes.

Korean Culinary Uses

DishMethod
Namul (Seasoned Side Dish)Toss blanched leaves with:
– ½ tsp sesame oil
– ½ tsp soy sauce
– 1 minced garlic clove
– Toasted sesame seeds.

KimchiFerment with napa cabbage, radish, and gochugaru (chilli flakes).

Claimed Nutrition

  • Claimed to be rich in vitamin C, iron, and fibre.
  • Contains oxalates (like spinach) – blanching reduces these.

💡 Why UK Gardeners Should Grow It

  1. Low Effort: Pest-resistant, perennial, and cold-hardy.
  2. Productive: One plant = continuous harvest (April–October).
  3. Soil Improver: Deep roots break up compacted soil.
