The thing about flowers unless you confine them to a flower bed or specific area is they tend to become wildflowers gradually expanding their territory.
That’s a good thing though as I believe they become more robust, less dependent.
Birds, bees, an assortment of insects, and even field mice take it to be a banquet and nothing wrong with that either.
In the planting of “domestic” flowers I’ve happened upon them a quarter to half mile away of their own volition adding an additional splash of color to nature’s palette.
That pleases me when I see they are visited by bees and other pollinators.
But I also confess that along with the “gatherers” when hiking to strewing handfuls of flower seeds about with the thought in mind that if they don’t take hold then they’ll provide nourishment for birds and forest denizens.
Weeds are one thing but an understanding has been arrived at that flowers have a free hand, if they start doing the land grab thing among the edibles easy enough to relocate them, and marigolds are a welcome addition to any vegetable garden as an insect repellent.
I tend to think of flowers as women – some have a gentle strength, some are fragile, and some are a little thorny, but they all serve an important purpose and even in the midst of the weeds life can hand you they add a splash of color to balance things out.
