Tanyosho Pine

Tanyosho pine is an evergreen Japanese red pine cultivar with a distinctive rounded, umbrella-like outline and green needles. Its mature size can vary with rootstock and whether the plant is trained, so allow room for a larger tree instead of treating a nursery size as a fixed mature dimension. ## Form and Placement The name Tanyosho Pine is used for *Pinus densiflora* ‘Umbraculifera’. Oregon State University describes the cultivar as slow-growing, often multistemmed, and mushroom-shaped; it may reach 12 feet or more, with size depending on rootstock. Use it as a focal evergreen where the irregular umbrella form can develop. ## Growing Conditions Plant in full sun and provide slightly acidic, well-drained soil. Oregon State University lists it for USDA zone 4 and notes that catalog estimates for mature height vary. Avoid saturated planting sites and leave space around the canopy. ## Maintenance Water consistently while the root system establishes, then adjust irrigation to local rainfall and soil drainage. Keep mulch away from the trunk and inspect the canopy periodically for dead, damaged, or crossing branches.
