Pollination Info for Baker's Colorado Blue Spruce (Picea pungens 'Bakeri')

Baker's Colorado Blue Spruce (Picea pungens 'Bakeri') is a monoecious conifer, meaning it has both male and female cones on the same tree. However, it is wind-pollinated and does not rely on insects for pollination.

The male cones, also known as pollen cones, are smaller and usually found in clusters near the base of new spring growth. When they mature, they release large amounts of pollen into the air. The female cones, or seed cones, are larger and take two years to fully mature. They are found on the upper branches of the tree and are pollinated by the wind-blown pollen.

Baker's Colorado Blue Spruce does not require another tree for pollination, as it is self-fertile.

It is important to note that excessive pruning or removal of current year's growth can reduce the tree's ability to produce cones and limit its reproductive potential.
