Hi, I find out many unknow plants as I just move in to a new house. May I know if this one is a weed or not. Please kindly help identify it so that I know how to handle it. Many thanks.
We believe this plant is Solidago spp, or Goldenrod, a native plant that self-seeds liberally in the garden. Some gardeners remove it; others like to leave it in place for its blooms – a splash of golden colour in the late summer. There are so many species in North America that it is impossible to determine which one it is unless it is in bloom. Here is a link to a great little blog post with more information about this plant: https://torontogardens.blogspot.ca/2009/09/all-that-glistersmight-just-be.html
