About Japanese white pine
Pinus parviflora, also known as Japanese White Pine or Five-needle Pine, is a majestic, slow-growing conifer with a pyramidal shape that matures into a broad, sculptural crown. Its soft, blue-green needles, arranged in bundles of five, give it a delicate texture and exceptional visual appeal. It is ideal as a specimen plant in Japanese-style gardens, as a bonsai, or as part of a rock garden.
Native range
Japan, Korea, and eastern Russia
Care tips
This pine requires full sun for optimal growth and well-drained, slightly acidic to neutral soil. Watering should be moderate, allowing the substrate to dry out slightly between waterings, and it's crucial to avoid waterlogging, especially in winter. A common mistake is over-pruning or pruning at the wrong time, which can weaken the plant; it's best to perform light pruning to maintain shape and remove dead branches. Protect young roots from severe frosts in very cold climates.
