Coniferous trees are evergreen plants typically found in mild to colder climates. Conifers harden in winter to prevent freezing and death in extreme cold.
Coniferous plants are uniquely pollinated by wind-blown pollen that fertilizes their cones. The cones are the reproductive organ of coniferous plants.
Balsam firs are a coniferous tree which can reach up to two hundred years in age. Balsam firs are known for the resin which accumulates in bark blisters and seeps out creating a fragrance to the tree.
Conifers do not have leaves but instead have needles which they keep from 2 to 15 years, depending on the species. Coniferous plants do not flower or fruit.
Coniferous forests in Asia and Canada are in danger due to acid rain. Acid rain destructs native soils and renders soil unlivable for coniferous trees.
The largest coniferous trees are the redwoods in northern California. These coniferous trees can grow up to 300 feet tall and 8 feet wide.
