I live in the Scarborough area and have been informed that Goldenrod and Sumach that grows in the garden are noxious weeds. Can you confirm if this is so? Canada goldenrod, scientific name Solidago canadensis L. It is a native perennial plant that is found throughout much of Ontario and can spread via seeds or rhizomes a type of underground stem.
Goldenrod is now being recognized and enjoyed as an excellent choice for a pollinator garden as it is both host and food source to a wide array of insects, moths and caterpillars. Ragweed, which flowers at the same times as Goldenrod but has a less conspicuous bloom, is the cause of many seasonal allergies. Sumacs Rhus spp. Sumacs spread by underground rhizomes horizontal underground stems that put out lateral shoots and adventitious roots at regular intervals.
As a result, Sumacs have the potential for forming large clones thickets. Like Goldenrod, Sumac blooms and seeds are a food source for a variety of insects and birds. One of the most common local sumac varieties is the Staghorn sumac, Rhus typhina L. It is not poisonous. Poison sumac Toxicodendron vernix has a similar leaf arrangement but they are usually smooth-margined. Want to stay up to date with this post?
