Occurrence

The homeland of the spotted milkweed is America and stretches from southeastern Canada to Belize and includes Cuba and the Bahamas. However, it also occurs as an introduced plant in southern and central Europe and is naturalized here in many places as well as in other countries in Asia, Africa and America. It grows in step societies on paths and in pavement joints, e.g. B. in cemeteries, brownfield sites and sidewalks. Here it likes to grow in Central Europe in the turf community of the knotweed ( Polygonetum calcati ), but is a species of the order Plantaginetalia majoris . It prefers dry, warm, nutrient-rich, mostly sandy soil with little fine soil.
