Decorative pyramidal shape. More resistant than Pinus nigra.
A close relative of Bosnian pine, this slow-growing evergreen tree is prized for its toughness and beauty. It is native to the Balkans.
This dense, sometimes shrubby pine bears long, rigid, sharp, medium- to dark-green needles in bundles of two. In spring, trees produce tiny male cones and oblong, egg-shaped female cones on the previous year's growth. The female cones are covered with purple scales that turn woody and yellowish brown as they mature. In their second year, female cones open their bracts to release winged seeds.
This pine slowly develops into a small to medium-sized tree with a narrowly oval to conical crown and a scaly, platy, ash-gray trunk.
Heldreich pine does best in ample sun and moist, well-drained, acidic to alkaline soil. Its tolerance of salt spray makes it a great selection for seaside landscapes. Use it as a single specimen, or cluster it in groves or windrows. (info source: Learn2Grow.com)

| Useful Info | |
| Germination | 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. |
