How to tell if a plant is a weed
Extension experts say weed control starts with correct identification, since annuals and perennials respond differently and some plants can outcompete turfgrass and garden crops.
The University of Minnesota defines a weed as any plant considered undesirable, unattractive, or troublesome when growing where unwanted, establishing that a weed is fundamentally a plant growing where it is not wanted.
Sometimes, spirited arguments about weeds appear on Facebook gardening groups, as discussion often becomes less about identifying plants and more about defending gardening philosophies; there is room for differing views.
Wild violets and purslane bring mixed reactions among gardeners. One person sees charming purple flowers, while another sees heart-shaped plants spreading vigorously and difficult to control.
Penn State Extension emphasizes that correctly identifying a weed is an important first step in determining the best control method. Colorado State University adds that weeds compete with plants gardeners prefer.
In conclusion, one gardener's weed can be another gardener's wildflower, ground cover, or edible green, and that is the wonderful thing about gardening: we don't all have to agree.
