Honey Locust in Snow

Many plants are used for landscaping in areas well beyond their natural range. One popular example is Honey Locust, which is indigenous to the Midwestern United States, but is grown extensively in cities and towns in the eastern part of the country. In some cases, including that of Honey Locust, the practice of growing plants outside their range is relatively harmless. However, some non-indigenous species, including the related Black Locust, are invasive and can crowd out indigenous plants in natural areas.Hello JavaGAR -

The subject of your post - invasive plant species - is a pet peeve of mine. Here's the scourge of the California coast, Pampas grass (Cortaderia jubata):

I hate the stuff! It quickly smothers all native plant species, leaving nothing but pampas and bare dirt. The coastal natives are tough, wind and drought resistant plants of large variety. But, two plants up to the challenge of annihilation are Pampas grass and Eucalyptus trees.Both are escapees from backyards and have been spreading like crazy since the '50s.
