     Bamboo-like, able to grow through concrete and described as “one of the world’s worst invasive species” by the International Union for Conservation of Nature, knotweed is invading the  Capital Regional District in Victoria. “Knotweed is quite widespread in the region, but not to the point where we can’t get ahead of it,” said Rachelle McElroy, executive director for the Coastal Invasive Species Committee.  Identifiable by its hollow, bamboo-like stems, large green leaves, small white flowers and red coloring along the stem, the plant is a troublemaker worldwide; some U.K. homeowners have been disqualified for mortgages because of the plant’s destructive presence.
