The Weeds to Look Out For

Here are some of the invasive weeds that you can find around Lillooet, BC.  Although this is a blog about Lillooet WILDFLOWERS... I felt that it may be nice to have examples of the different stages you will find these weeds.  During our annual wildflower count I am hoping that we can compile names of invasive weeds found in the areas that we are canvassing, as well as our native species.
