This pine is one of the most decorative and grows in a wide climate scale - from cold northern regions to warmer sites. They are probably most beautiful in their natural environment.
It is an excellent choice if you are looking for compact growing conifers. It has a conical growth without a need for trimming. Needles are dark green, long, growing upright. A mature tree can grow to 10m, however, it does not hurry as its parent Austrian pine.
Thrives in a light well-drained sandy or gravelly loam. Dislikes poorly drained moorland soils. Established plants tolerate drought. Requires a sunny position. A very hardy tree, it is extensively planted for timber and shelter, tolerating maritime exposure. Fast growing when young.
Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus. Leaf secretions inhibit the germination of seeds, thereby reducing the amount of plants that can grow beneath the tree.
Trees tend to be short-lived in cultivation. Plants in this genus are notably susceptible to honey fungus.

1. Place the seeds in a container with tepid water and soak them for 24 hours. Change the water and wait another 24 hours.
2. Put the seeds in a small plastic bag and cover with damp sand. Place the bag holding the seeds in the refrigerator for one to two months to stratify the seeds, which is preserving seeds in layers of moisture-laden peat, soil or sand. Check the sand and water as needed to maintain moisture. Don't allow the seeds to get soaked.
3. Fill small pots with compost. Place one or two pine seeds on top of the compost in each pot, then cover the seeds with a thin layer of sand.
4. Water the sand and compost to add moisture, then place the pots in a warm, sunny location. As the seedlings emerge and grow, the soil needs to remain moist, not wet.
5. Repot the pine trees into medium-sized pots in the fall. Grow them in the pots for the following season until they are large and strong enough for transplanting into the landscape.
