Norfolk Island Pine Seed Pods: Size, Weight, and Safety Concerns

Cone Dimensions

Norfolk Island Pine (Araucaria heterophylla) cones are large—about 6 inches long and slightly wider than a beer can.

Surprising Weight

In favorable climates (Hawaii, Australia, South Pacific), cones can weigh up to 5 kg (11 lbs). A relative, Araucaria bidwillii, produces cones up to 22 kg (44 lbs)—hazardous enough that warning signs are posted to prevent injury from falling cones.

Botanical Note

Araucaria species are not true pines despite the common name.
