Thunderhead pine is a medium-sized evergreen conifer and a compact cultivar of Japanese black pine. It has an irregular growth habit that adds year-round beauty and character to any landscape. Its densely packed dark-green glossy needles and silver-white candles or new shoots are an attractive addition to your late winter or early spring garden. The needles are 3.5 to 4.5 inches long and occur in bundles of two. The cones are up to 3 inches long, oval, and brown.
The cultivar originated in 1987 as a seedling selected at Angelica Nursery in Kennedyville, Maryland.
This plant prefers full sun, moist, well-drained soils of loam or sand with a neutral to acidic pH. It prefers cool night temperatures.
The Thunderhead pine is an excellent choice for a courtyard garden or small city garden. It may be used as a focal point for an Asian or cottage garden. It looks great pruned and sculpted into an artistic shape or left in its natural form. It grows in a tight, upright mound.
