Canada goldenrod

Canada goldenrod, tall golden rod, yellow-weed or yellow-top, scientific name: Solidago altissima, is aperennial grass of the Asteracdepartment , of the Solidago genus native to North American .Breeding in a sunny Glade and its large and expanding sphere of influence.

Like Japanese mugwort (scientific name: Artemisia princeps), it is considered problematic because it secretes a substance called "allelopathy" from its underground stem that inhibits the germination of other plants, thereby destroying other plants, including native Japanese species. The battle with Miscanthus sinensis (scientific name: Miscanthus sinensis) is especially tremendous.
It produces large conical inflorescences with densely clustered small head flowers. Since it is an insect-mediated flower, it is not considered to be a factor in the onset of pollinosis, unlike wind-borne flowers. Beekeepers use it as a source of nectar in the fall. It is similar to the giant goldenrod (scientific name: Solidago gigantea var. leiophylla), which is in the same family.
