Pinus aristata

Bloom Color: Yellow. Main Bloom Time: Early spring, Late spring, Mid spring. Form: Oval, Pyramidal.

Pinus aristata is an evergreen Tree growing to 12 m by 4 m at a slow rate.
It is hardy to zone 3. It is in leaf all year, and the seeds ripen in October. The species is monoecious and is pollinated by Wind. The plant is not self-fertile.
Suitable for: light and medium soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: acid and neutral soils. It cannot grow in the shade. It prefers dry or moist soil and can tolerate drought. The plant can tolerates strong winds but not maritime exposure.

Landscape Uses:Screen, Specimen. Thrives in a light well-drained sandy or gravelly loam. Dislikes poorly drained moorland soils. Established plants tolerate drought. A wind tolerant tree, it often grows on very exposed ridges in the wild. Trees grow best in areas with cold dry summers, the largest cultivated specimen is in dry sub-continental north-east Iceland. A very slow growing and short-lived tree in Britain, though it lives for 2000 years or more in its native range. This is the oldest known living plant with specimens over 4000 years old. This species is closely related to P. balfouriana. The cones open and shed their seed whilst still attached to the tree. 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 inhibiting the growth of other plants below the tree. Plants in this genus are notably susceptible to honey fungus. Special Features:Attractive foliage, North American native, Inconspicuous flowers or blooms.
