About Swiss stone pine
Pinus cembra, also known as Swiss stone pine or Arolla pine, is a slow-growing coniferous tree with a conical or columnar shape, developing a dense, pyramidal crown. Its dark green needles are grouped in fascicles of five, and it produces attractive cones that mature over three years. It is ideal for mountain gardens, alpine rockeries, or as a specimen tree, adding a majestic and rustic touch.
Native range
European Alps and Carpathian Mountains
Care tips
This tree requires full sun for optimal growth and prefers well-drained, slightly acidic to neutral soils. Watering should be moderate, especially during the first few years, avoiding waterlogging as it is sensitive to excessive root moisture. It's crucial to plant it in a location with good air circulation and avoid severe pruning, as it is slow-growing and may take time to recover. A common mistake is planting it in hot and humid climates, where it does not thrive.
