The showy purple flowers appear in corymbs that slightly bend the stems. They bloom during the second half of summer. They are used to form clumps, flower beds and as a bottom for low-rise herbaceous plant beds. Eupatorium purpureum needs full sun exposure; they resist occasional frosts down to -1 ºC (30.2 ºF). The soil should contain abundant organic matter such as leaf mulch or well-decomposed manure. Water abundantly in summer and reduce watering the rest of the year. Keep in mind that this plant comes from swampy areas. Fertilize with manure or compost in the fall or early spring. They do not need pruning. They can be attacked by mealybugs, aphids and mites if they suffer from drought. They propagate by seeds sown in spring or autumn and by division. |
