Aegopodium–commonly called bishop’s weed–is a ground-covering perennial that will grow where many other plants will not. It can be used as spreading ground cover but should be grown apart from most other plants; it spreads via rhizomes and can be invasive when grown near other plants.
Aegopodium bears deep green leaves; each leaf consists of three ovate leaflets. Many rayed umbels of white flowers are borne on branching, hairless stems.
Aeogopodium grows best in partial to full shade. It will thrive in any soil, even poor, dry soil. Aeogopodium puts down deep roots so it is best to plant it where it can grow undisturbed for a long time; it is difficult to eradicate. It is a good choice for shaded urban situations where little else will grow and its spread is controlled by sideways or roadways.
Aeogopodium is a genus of 5 species of perennials with invasive rhizomes. Aeogodium is native to woodlands in Northern and Central Europe.
