Tropical Pine Trees

However, there are a number of pine species which can also grow well in the hot and damp tropical environment. Some famous examples of these pine species include Norfolk pine, Sand pine, Spruce pine and Pond pine trees. They can be adaptive to the high-moisture conditions and flourish happily.

They prefer to grow in full sunlight and well-drained soil conditions although they can tolerate a number of soil types.
