The Swiss pine is one of the most beautiful and at the same time rarest trees in the Alps. The tree grows to between 12 and 25 metres and forms the treeline, often together with the larch tree. The needles of the Swiss pine are five to eight centimetres long and five of the needles are located on a dwarf shoot, resistant to temperatures of down to minus 30 degrees Celsius. The cones, which grow upright on the tree, reach a size of six to eight centimetres. In order to flourish, the Swiss pine needs raw humus soil which is also the reason it is mainly found in the Central Alps and Carpathian Mountains. A special feature of this rare beauty is that they grow to become up to 1,000 years old and only bloom in June and July every six to ten years.
