| 'Hornibrookiana' originated from a witch's broom on an Austrian pine in New York's Seneca Park in 1932. This wonderful upright mounding shrub starts out as wide as it is tall, and has long, stiff, dark green needles that are retained all year, even in cold, windy climates. Its needles grow in bundles of two and are approximately two to three inches in length. The compact habit is easily maintained at the desired size, but will generally mature at two feet tall by three feet wide. Zone 4-7. Pinus nigra (Austrian Pine) - Conifer, evergreen tree, 50-60(100) ft [15-18(30) m], densely pyramidal when young, becoming a large flat-topped tree with a short, straight trunk and stout spreading branches. Bark light gray to dark brown, darker than P. ponderosa. Buds ovate to cylindrical, resinous. Needles in pairs, persist 4-8 years, 8-12 cm long, stiff, point sharp to touch, bundle sheath 13 mm long, 12-14 stomatal lies on each surface. Cones grouped 2-4, ovoid, conical, 4-8 cm long, light brown.
