Japanese Black Pine Seeds (Pinus thunbergii) – Dormant Bonsai Seed

Johnny Mapleseed

Grow one of the most iconic and durable bonsai conifers from seed. Japanese Black Pine (Pinus thunbergii) dormant seeds are prized worldwide for their rugged bark, powerful trunk development, and classic coastal character. A cornerstone species in traditional Japanese bonsai, this pine is equally valued as a specimen tree in challenging environments.

Native to Japan, Japanese Black Pine is exceptionally salt tolerant, heat tolerant, and pollution resistant, making it a top choice for coastal plantings and urban landscapes. In the wild, it can reach up to 120 feet tall, where it plays a vital role in erosion control by stabilizing sandy soils. For bonsai, it responds well to pruning and needle-reduction techniques, producing a refined yet masculine appearance.

With thick, slightly twisted bright green needles up to 4.5 inches long and rugged, fissured bark that develops early, Pinus thunbergii creates the look of age and strength that bonsai artists seek. It is relatively disease-resistant and tolerant of poor soils, making it suitable for both beginners and experienced growers.
