weed

Phragmites is a non-native perennial grass this is commonly referred to as common reed. The wetland grass thrives in its name sake - wetlands or low areas - but can also establish itself in other areas. It is commonly found along roadsides in ditches, in retention ponds and bioswales, along the edges of ponds, rivers and lakes, and will completely infiltrate a wetland, quickly becoming a monoculture - single species. It is considered invasive as it outcompetes all other plants and displaces wildlife as it becomes the top-plant, at least in numbers, in a given area.

Dandelions and clover may be the first to pop to mind when considering lawn weeds, but this was the first time I had seen violets in turf.
