Australian Pine

The Australian pine is a tall, non-native tree found throughout South Florida and parts of Central Florida. It was introduced to Florida in the late 1800s as a salt-tolerant tree that could provide shade and serve as a windbreak along coastal areas.

But since then, it has become a major problem. It’s an aggressive grower that spreads into natural areas and smothers native plants under a heavy blanket of needle-like litter. Its pollen is highly allergenic. The State of Florida has classified Australian pine as a noxious weed and prohibits people from cultivating or planting it.

If you have one on your property, consider making a Florida-Friendly choice and having the tree removed. That way, it won’t be able to spread its seeds into natural areas.
