Pinus heldreichii 'Irish Bell' is an upright dwarf selection of Bosnian pine, with dense symmetrical branching and shorter-than-typical bright green needles that reveal bright-white fascicles from within. After 10 years of growth, a mature specimen will measure 4 feet (1.3 m) tall and 36 inches (90 cm) wide, an annual growth rate of 4 to 5 inches (10 - 12.5 cm).
According to the Iseli Nursery online catalog, 'Irish Bell'™ presents a handsome, broadly pyramidal form that stays compact, neat and well-mannered. Trees gradually widen into a classic bell shape, narrow at the top, broader near the ground and about as wide as tall. A mature 'Irish Bell'™ displays a colony of upright branches, each one decorated with tufts of straight green needles and glistening white fascicles. The bright white accent gives the impression that light dances among the needles, a feature that accentuates the beauty of this useful ornamental pine and adds to its value as a striking garden specimen. Well-regarded in the trade, this selection is a good choice for urban and suburban gardens for year-round impact.
This cultivar originated as seedling selected in the late 1990s by Iseli Nursery, Boring, Oregon, USA.
