Discussion Coulter Pines produce the largest cones of any pine tree species (people are actually advised to wear hardhats when working in Coulter Pine groves), although the slender cones of the sugar pine are longer. Large size of the cones has earned them the nickname "widowmakers" among locals. Wood is weak and soft, little used other than for firewood. Occasionally planted as an ornamental tree in parks and large gardens.
