About
Pinus monophylla, the single-leaf pinyon, is the only pine with needles produced individually rather than in bundles. A slow-growing, rounded to irregular tree from the American West producing solitary, stiff, grey-green needles and small, rounded cones with large, edible seeds. An architectural and food-producing conifer for a well-drained, sunny garden.
About the genus
Pinus, the pines, are evergreen coniferous trees or shrubs � some with attractive bark � developing an irregular crown with age and bearing long, needle-like leaves in bundles of 2, 3 or 5. Conspicuous cones may fall or persist on the tree for years. Among the most widely grown of all ornamental conifers.

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.
