Pinus densiflora 'Umbraculifera' (Tanyosho Pine, Japanese Red Pine)


Michael's Opinion

Tanyosho Pine is a multi-stemmed evergreen that has a very dense form. Develops exfoliating bark with age, revealing reddish-orange tones on its underside. These features make this tree a perfect accent specimen to set off any landscape.
