What it's good for, and what it isn't

A very slow, dense dwarf pine that forms a flattened globe: its soft, bright green needles in pairs may turn slightly yellowish in winter, and reddish brown bark shows on old plants. It grows more outwards than upwards and makes a mound roughly knee to waist high and a little wider in ten years, so it suits rock gardens, the front of gravel beds, front gardens and larger containers, and it hardly ever needs pruning. Give it full sun and free-draining, slightly acidic to neutral soil; it will not stand waterlogging.

Watch out for
On heavy, wet soil it dies from root suffocation, and it does not do well on strongly limy soil. In Central Europe the fungi that attack two-needled pines, mainly Diplodia tip blight and Dothistroma or Lophodermium needle diseases, can appear on it, mostly on plants weakened by a hot, dry summer; water newly planted and container plants in summer. The needles may turn yellowish in winter, which is not a disease. Sources differ a lot on its size (some give 40 cm after ten years, others about a metre), and plants grafted on a stem grow taller, so ask what you are buying.
