“When one with honeyed words but evil mind
Persuades the mob, great woes befall the state.”
Continuing on my “purple phase” theme, here’s a beautiful invader. Though a beautiful flowering plant, in Ontario and other areas where it was introduced as a garden flower, this garden escapee soon established itself in meadows and wetlands, crowding out native plants.
It spreads through rapidly spreading rhizomes and seeds. Each plant can produce over one thousand seeds. It also has no naturally occurring predators, so it spreads uncontrolled, though something, likely earwigs or slugs, seems to be feasting on the leaves below the blossoms.
The plant was spreading like wildfire a few years ago, but recent dry and hot summers seemed, coupled with human efforts to eradicate it, seemed to be taking its toll on the population. This year, which has been extremely wet, seems to have enabled it to bounce back and I’ve seen much more of it an areas where it has not previously occurred. SO the battle goes on.
It’s a shame that such a pretty plant needs to be so aggressively invasive. But, that seems to be a common theme. Plants are introduced from overseas because they are beautiful in gardens, but once they escape, without natural controls, they can quickly take over. The dandelion is perhaps the best known example. Imported for its food value centuries ago, it has now spread to every corner of the continent. However, as evidenced in this image, local insects wildlife also adapts and soon begins to eat the introduced species. Nature is quite adaptable, but with limits.
