'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.
