Pinus mugo var. rostrata 'Big Tuna' is a large, upright, broadly conical multi-stemmed bush with thick, dark green needles. Its form can be described as "like huggable teddy bear." According to the Iseli Nursery website, it grows taller than it does wide in a somewhat pyramidal shape and is thickly branched from top to bottom. Although a medium-size shrub, 'Big Tuna' still has lush, compact growth, ultimately reaching 6 to 8 feet (1.8 to 2.4 m) tall by 4 to 6 feet (1.2 - 1.8 m) wide after 10 years in the landscape.
Iseli Nursery Inc. of Boring, Oregon introduced with bold selection in 1976. This is a great plant for landscape situations that call for a more substantial presence.
