Prostrate knotweed (Polygonum aviculare)

Prostrate knotweed (Polygonum aviculare) is a ground-hugging plant that can establish itself almost anywhere. It blooms with numerous small white flowers during the summer and generates a large quantity of seeds that remain viable for years. These seeds can stay dormant in the soil and germinate when exposed to sunlight. Due to its very low growth habit, mowing does not effectively eliminate prostrate knotweed, as the blades typically miss cutting it, and it can easily regrow from its resilient root system.
