Male and female cones occur at the tips of the branches on separate plants.
The male cone is small and cylinder-shaped, with 8 to 12 pollen sacs that
release pollen in February and March. Female plants bear the characteristic
blue, fleshy, berry-like cones that ripen in one year and contain 1 to 2
small, ovoid, shiny seeds. Large seed crops are produced every 3 years,
and seeds require 2 to 3 years to germinate. Plants are freely self-seeding
and the seeds germinate in any soil. |
