Cultivars/Varieties

‘Globosa’ – This plant becomes a dwarf rounded mound to 15′ in many years. The needles are short and deep green, with a prostrate, slow-growing trunk.

‘Low Glow’, ‘Little Christopher’ (also known as ‘Rezek’s Witch’s Broom Seedling’) and ‘Tiny Temple’ (also known as ‘Temple’) – These are miniature forms that grow slowly and form tight mounds of deep green needles.

‘Oculis Draconis’ – A favorite among lovers of variegated foliage, the “Dragon’s Eye Pine” is an unusual form that bears needles with alternating bands of green and yellow coloring. When viewed from the proper angle, the foliage resembes a “dragon’s eye”, thus the common name. It forms a large shrub or small tree.

‘Pendula’ – A strong weeper, this cultivar needs training or grafting to maintain it as an upright tree. Otherwise, it can creep over the ground as a prostrate creeper. The needles are deep green and the bark becomes reddish.

‘Umbraculifera’ (also known as ‘Tanyosho’) – Commonly known as “Tanyosho Pine”, this is a popular form. It forms a multi-trunked tree or large shrub to approximately 20′ tall and wide. The habit is vase shaped with an umbrella-like head that becomes flat-topped with age. The bark shows good orange color. It is often employed as a specimen or accent plant, though it can suffer severe damage from heavy snow or ice loading. The plant is cold hardy to USDA zone 3. ‘Umbraculifera Compacta’ and ‘Jane Kluis’ are dwarf forms of the cultivar with similar habit. They reach 4′ to 6′ tall.
