About
A large and diverse genus of mainly annual or perennial, often invasive, herbs with willowy, simple leaves and erect racemes of showy, four-petalled, pink, purple, or white flowers from summer into autumn. Most species are suited to moist soils, but the genus contains species for a range of habitats.
About the genus
Pinus can be shrubs or large, evergreen trees, some species with attractive bark, developing an irregular outline with age and bearing long needle-like leaves in bundles of 2, 3 or 5; conspicuous cones may fall or remain on the tree for years
Plant details
Suggested usesSpecimen planting, shelterbelts, large gardens. Dwarf cultivars suit rock gardens and containers.
Care notes
CultivationWell-drained, preferably acidic soil in full sun. Most pines are very drought-tolerant once established.
PruningNo regular pruning needed. Remove dead branches. Candle-prune in spring for density on dwarf types.
PropagationSow seed in spring (stratify first). Grafting for cultivars.
Pest resistancePine processionary moth, adelgids, pine shoot beetle. Generally robust.
Disease resistanceDothistroma needle blight, Diplodia tip blight. Good air circulation helps.
