About

*Arum italicum* is a handsome tuberous perennial that thrives in exactly the conditions found in the Monkey Puzzle Strip — sheltered, part-shaded, and with humus-rich soil. It has an unusual growth cycle: the foliage emerges in autumn and persists through winter and spring before dying back in early summer. In late summer, vivid orange-red berries on bare stems make it highly ornamental. The subspecies *marmoratum* has attractive silver-marbled leaves.

Key Characteristics

  • Type: Deciduous/winter-growing tuberous perennial, family Araceae
  • Leaves: Large, glossy, arrow-shaped (sagittate); often with pale silver veining or marbling; emerge autumn, die back early summer
  • Flowers: Pale greenish-yellow spathe (April–May) — unremarkable
  • Berries: Bright orange-red, borne on bare stems in late summer — very striking; toxic if eaten
  • Size: 30–45 cm tall in leaf

Seasonal Calendar

Month What to expect
Autumn (Sep–Nov) New foliage emerges — the showiest period
Winter (Dec–Feb) Foliage persists; attractive through frost
Spring (Mar–May) Foliage at its boldest; flowers appear April–May
Early Summer (Jun) Foliage yellows and dies back
Late Summer (Aug–Sep) Vivid orange-red berries on bare stems — very ornamental

Care Notes

Aspect Details
Hardiness Hardy to −15°C (Zone 6)
Soil Humus-rich, moisture-retentive; tolerates heavy soil
Sun Part shade to full shade; ideal under deciduous or coniferous trees
Watering Little needed once established; benefits from moisture in autumn/winter
Maintenance Virtually none — cut back old flower stems after berries; divide tubers if clumps become congested
Spreading Self-seeds and spreads by offsets — can naturalise freely

Notes

  • All parts are toxic — berries are tempting but dangerous, especially to children and dogs
  • Excellent for filling shady spots under trees where little else will grow
  • Pairs well with ferns, ivy, and hellebores in the woodland garden
  • The marbled foliage of *A. italicum* subsp. *marmoratum* is especially decorative
