invasive plants

**Saxon Holt s*@saxonholt.com**

Many garden plants can be considered invasive depending on local conditions,
though I find it amusing when someone calls a native invasive in its own
region.  California poppies would be considered invasive in my California
garden.

I believe the official use of the word "invasive" refers to those plants
that spread and continue to propagate in wild regions other than their
native one.  (One day though, we will have to consider planet earth as all
one region because of the inexorable migration of plants aided by humans -
like it or not).

Many plants will be considered aggressive in garden settings but not
invasive.  But whether or not it is technically "invasive", garden writers
should keep reminding gardeners to know the plants.

Anyway the USDA keeps a database of invasive plants in conjunction with the
Natural Resources Conservation Service:

Since I do not want to get into arguing with my government on this list
(don't get me started, folks . . .  ) let's use that to help define
"invasive".
