Production
The umbrella pine — a stately long-term anchor grown for prized pine nuts and a broad shading crown. Handsome and tough, but patience is required: nuts take decades, and it's flammable in dry heat.

How to manage it
Give it a wide gap in the canopy top layer and let it run — it's slow to bear, so plan for 15-20 years before a reliable pine-nut harvest. Clear competing trees as it matures into the emergent layer.
Watch out for
Resinous wood and needles make it fire-prone in dry summers; acidic needle litter can suppress understory germination. Cones take about three years to ripen, so nut yield is a long game.
