Invasive plants – why should you care?
August 18, 2011
There is not enough awareness when it comes to invasive plants. We tend not to see the harm in planting an invasive plant precisely because it seems so harmless. How can a plant hurt anything?
An “invasive species” is defined as ‘an alien species whose introduction does or is likely to cause economic or environmental hard or harm to human health.’ (Executive Order 13112).
An invasive species spreads, establishes its presence and takes over an ecosystem. It does not co-exist, it overtakes, chokes out the native species and diminishes biodiversity. It is devastating to the native ecosystems and costly to control. Did you know? “Invasive species are a significant threat to almost half of the native species currently listed as federally endangered.” Lady Bird Johnson Wildflower Center
Why should we care? Because native plants and habitats are important to our identity, sense of place and survival. To preserve ecosystems and biodiversity which are vital to our planet’s health.
Information about invasive species is spread out and often confusing. It is important to know the invasives for your particular region. Some website list them by state, some go as far as listing them by county. Below are some useful links to invasives in Texas.

Some of the invasives are sold by nurseries and many buyers are unaware of the plant’s nature. Purple loosestrife, vitex and nandina are some fairly well known examples. Sterile varieties of some invasive species are available and can be used safely in the landscape.
