The Bonsai Stone Pine (Pinus pinea) is the quintessential Mediterranean tree. Famous for its iconic umbrella-shaped crown, this pine defines the coastal landscapes from Italy to Portugal. With this seed set, you can grow your own Stone Pine — as a beautiful bonsai or a striking patio plant.

Growing Guide: How to Sow

  1. Soak seeds: Submerge in lukewarm water for 24 hours to soften the hard shell.
  2. Cold phase (recommended): 4 weeks in the fridge at 4–5 °C in damp sand significantly improves germination.
  3. Sow: Plant seeds 1 cm deep in well-draining substrate (seed compost mixed with sand or perlite).
  4. Germination: At 18–22 °C with consistent moisture, seeds sprout in 2–4 weeks.
  5. Repot: When seedlings reach 5–8 cm, transplant into individual pots.

Care Tips

  • Bonsai shaping: Start pruning after 2–3 years. Ideal for upright and literati styles.
  • Umbrella shape: The iconic flat crown develops naturally over the years.
  • Pine nuts: Pinus pinea produces the famous pignoli — though in pots this takes 15–20 years!
  • Winter: Tolerates light frost to –10 °C. Provide a cool, sheltered spot (5–10 °C) in winter.

FAQ

Bonsai or garden tree?
Both work beautifully. As a bonsai, it develops stunning character. In a large container, it grows its natural umbrella shape.

Can I keep it indoors?
The Stone Pine prefers outdoor conditions with full sun. For bonsai, summer outside and a cool bright spot (5–10 °C) indoors in winter.

Will it produce pine nuts?
Eventually, yes — but patience is key. Cones take 3 years to ripen, and nut production begins after 10–20 years.

Includes: Pinus pinea seeds, multilingual instructions (DE/EN/IT/ES). Bag 13 × 13 cm.
