Do blue spruce trees produce pine cones?
The species is monoecious, and the male cones are reddish and mature to become brown, whereas female cones are purple. The male cones are all throughout the tree, whereas the female cones are at the top of the tree, which helps to facilitat cross polination. Cones are dry, hard, and pale brown.
Do spruce trees produce cones?
Many conifers, including spruces, firs and Douglas-fir, produce cones in a two-year cycle. White spruce trees, in particular, are producing large amounts of cones this year, although Serbian spruce and Norway spruce trees also appear to have higher than normal amounts of cones.
Should I remove cones from spruce tree?
Christmas tree growers want maximum new growth to help develop tree shape and density. These fir cones are a detriment. The other concern is that fir cones disintegrate in the fall; if they are not removed, large holes or gaps are left where the cones were growing.
Why does my blue spruce have so many cones?
When a harsh winter is on the way, pine trees produce as many cones as they can – they somehow “expect” that squirrels and birds share their opinion on the coming season, and will forage for more pine seeds to stock up ahead of time (you hear this one about other trees too – acorns, walnuts etc).
What are spruce cones good for?
All parts of the tree are non-toxic. Medicinal and nutritional qualities of the spruce include help with the respiratory system; active vitamin C, which fights against colds and infections; Spruce needles contain large amounts of shikimic acid, which is a flu-fighting compound and helps fight respiratory ailments.

Where do blue spruce trees get their pine cones?
As you might expect, pinecones come from pine trees, including the Colorado blue spruce trees that we grow here in the state of Colorado. Rather, the male cones release pollen which is carried by the wind to fertilize female cones, which then develop the scales that protect the seeds inside. Hereof, do blue spruce produce pine cones?
How many pollen grains does a blue spruce tree produce?
Most male strobili of blue spruce are rose red when they emerge from the buds, but on occasional trees they appear yellowish-green. A single male strobilus, containing 100 sporophylls, may produce about 370,000 pollen grains. The female strobili consist of 175 to 225 scales and thus have a potential to produce 350 to 450 seeds per cone.
Is a blue spruce a gymnosperm?
Is a blue spruce a Gymnosperm? Conifers like the spruce, cedar and pine tree are gymnosperms and have seeds on cones. The leaves or needles of coniferous trees lose less water than other kinds of leaves.
How do pine cones get pollen from male to female?
With male cones down low and female cones up high, pollen from male cones must get blown by the wind to get high enough to reach a female cone. This wind will usually carry the pollen to another tree. If, however, the cones were intermixed or the males were on top, the pollen would fall directly into its own female cones.
