National Invasive Species Information Center

Spotted Knapweed

For those who, like me in the past, think, psah, what does it matter if I bring some seeds from another country? Well, invasive species, aliens to our ecology, come in and not only take over, but destroy an ecosystem that is so linked to other ecosystems.


Like the berried Nandina that people have in their yards here in Western Oaks, if it doesn't spread by wind or rhizomes, the birds will eat the seeds and plop them where ever the soil will takes and voila, the spreading has continued. Learning about invasives and why they should be plain forbidden is a long study on its own. For now, perhaps whilst browsing or looking through your 'Grow Green Guide' from Austin, read up some more at the gov site of "National Invasive Species Information Center".

Try to go native at all times for your own specific area. There are a lot of South African plants that seem to do well here in Central Texas, just make sure that, where ever the plant is from, it is not invasive. You'll do your part in protecting our ecosystem with beneficial insects, protect from soil erosion and poisoning other plants. That one would be courtesy of the Knapweed plant. A European native that somehow made its way here probably through the trade of some other food item. Check out the link for some of our area's problem plants and make sure you do not have any.
