Clarification: Non-Native vs. Invasive

Back in my report on Day 6 of the Green Spring Gardens Master Gardner Program, I correctly identified some of the characteristics of invasive species as:

  • Fast growth and spread
  • Prolific seed production
  • Easy dispersal

But I failed to clarify that NOT all non-native species are invasive.

Non-native species are plants growing outside of the area where they evolved.

What makes them different from an invasive species is their rate of growth, prolific seed production and dispersal.

Invasive species outgrow surrounding plants, whether native or non-native, and overcome the habitat.

That was a big omission, and it took me a while to ask about it and get clarification. Now you know.

Cool plant. Non-native, but not invasive.
