Helping You Become a More Successful Gardener
Bishop's Goutweed is a fast-spreading Eurasian groundcover that has become naturalized across the whole of North America. It spreads via rhizomes (rooting underground stems) and has green compound leaves with three to nine leaflets. The equally weedy garden variety, 'Variegatum', is the most common form in cultivation and has leaves mottled with ivory.
In mid-spring to summer, goutweed produces umbels of tiny white flowers that are insect-pollinated and produce lots of brown seeds that spread and germinate quickly. Removing seed heads will curtail unwanted volunteer plants from seeding in, but plants spread just as aggressively via rhizomes, so pulling whole plants is the only way to truly eradicate them.
Like most weeds, this is not a picky plant; it will grow in full sun to shade and tolerate almost any garden soil with decent drainage. Plant only in areas where deep edging can be set into the ground to prevent roots from spreading beyond desired borders. Planting in a deeply shaded, dry location will reduce vigor. Cut back severely in summer to rejuvenate lush new growth for late summer and fall. The variegated cultivar 'Variegatum' is prettier but still quite invasive and to be avoided. Aegopodium podagraria is on the USDA list of invasive plants to avoid.
