More: This plant is dioecious and wind-pollinated. Dioicum and dioecious derive from the Greek meaning "two households". Both male and female plants are needed to set viable seed. Good to plant with bulbs and spring ephemerals as the foliage is attractive and persistent and will hide the gaps left by summer dormant species. Larval host for the Pink-tinted Beauty, Eosphoropteryx thyatyroides, which is native to Maine.
