🌳 Field Elm

Ulmus minor (syn. Ulmus campestris) · Ulmaceae

🌳 Temperate Europe
🧠 To remember it"Elm: the limping leaf" — its asymmetrical base, with one side longer than the other, is the fastest marker for the genus.
Field Elm — Ulmus minor (syn. Ulmus campestris)

🔍 Identify it without mistakes

Tree with oval, doubly serrated leaves that are asymmetrical at the base (one side of the blade extends further down than the other, a diagnostic key for the genus Ulmus), rough to the touch on top. Small, round, winged fruits (samaras) appear early in spring before the leaves. Grey bark cracking into plates with age.

  1. asymmetrical leaf base (one side longer than the other)
  2. doubly serrated leaves, rough to the touch
  3. round winged samaras appearing before the leaves
  4. grey bark cracking into irregular plates
  5. cambium (layer under the bark) mucilaginous and slightly sweet to the taste
Size15-30 m (mature specimens have become rare in Europe due to Dutch elm disease)
FloweringFebruary-March (before the leaves)
Habitathedgerows, forest edges, field borders, rich and moist soils — population severely affected by Dutch elm disease since the 1970s

⚠️ Not to be confused with

no dangerous confusion reported (-)aucun

To tell them apart: the asymmetrical leaf base is a reliable signature of the genus Ulmus, rarely shared by other common European trees

🍽️ Eating it

Partscambium (inner bark), young samaras, young leaves
Seasonspring (cambium and samaras)
Tastecambium slightly sweet and mucilaginous; tender samara mild; young leaf neutral

Preparation : cambium (the thin living layer under the bark) scraped and eaten raw, or dried and ground into emergency flour in times of famine — a documented practice among many forest peoples of Europe and North America; young and tender samaras eaten raw, slightly sweet; young leaves in salads at the very beginning of spring

💊 Healing with it

bark traditionally used as an emollient poultice for skin conditions, an application with little modern scientific documentation

Level of evidence : traditional use — ethnobotanical compilations (Couplan, Thayer)

⚠️ no major known contraindications; harvesting cambium must remain limited and sensible (it weakens or kills the tree if the ring girdles the trunk — reserve this technique for true survival situations)

🪓 Other bushcraft uses

  • dense wood resistant to rot in wet environments, historically used for submerged foundation piles (part of Venice's foundations rests on elm and alder piles)
  • bast fiber used for emergency cordage
