Japanese Black Pine ‘Senjumaru’

The Japanese Black Pine ‘Senjumaru’ (Pinus thunbergii ‘Senjumaru’) is a remarkable grafted cultivar developed at Ryoshoen, created by grafting a Kotobuki scion onto Japanese black pine stock. The resulting genetic mutation produces clusters of buds and exceptionally compact growth — making it ideal for small and refined bonsai development.

Named by AYADA Tadashi, Senjumaru inherits the prized short needles of Kotobuki while also exhibiting faster growth and improved branching. It is rapidly becoming the new standard for black pine bonsai in Japan, celebrated for its superior characteristics and exceptional performance in traditional bonsai cultivation.

Why Choose Senjumaru?

• Compact bud clusters: Genetic mutation produces dense, multi-bud growth points ideal for refined bonsai structure
• Short needles: Inherits the prized short needle trait of Kotobuki for a refined, miniature aesthetic
• Faster growth: Outperforms Kotobuki in vigour while retaining its compact character
• Improved branching: Superior ramification potential compared to standard black pine cultivars
• Japan’s new standard: Rapidly adopted by top bonsai practitioners across Japan
• Easy to grow: Suitable for beginners and experienced growers alike
