Thunderhead is a dense, broadly pyramidal Japanese black pine with long, glossy dark-green needles and striking silver-white candles (new shoots) in late winter and early spring. Vigorous, about 10 to 15 feet tall and up to 20 feet wide in 10 years, and easy to prune to size or shape as a garden bonsai. Hardy to zone 5, though needles can burn below about -10°F.
