What is an invasive plant?
An invasive plant will spread and prevent other plants from growing. Although beautiful in their own way, they dominate their ecosystem and don’t provide the nutrients needed by native insects and animals. Non-native plants share qualities of both: they produce foliage or blooms and don’t take over their habitat.
Do non-native plants take over their habitat?
Non-native plants share qualities of both: they produce foliage or blooms and don’t take over their habitat. But they’re often not adpated to the environment, and require more care than native plants. Sometimes the differences get blurred. For example, you can have a native plant that becomes invasive as it takes over your flowerbed.
