HORTICULTURAL
Plant Sale Text: Butterfly milkweed is a common roadside wildflower in our area, and like other members of Asclepias genus, is a host to monarch butterfly caterpillars. The distinctive linear leaves and bright orange flowers make butterfly milkweed a standout in summer. Its modest size provides a splash of color without overwhelming small spaces. Drought tolerant and deer resistant, this plants is a “must have” to support Monarch butterflies and up to 12 species of lepidoptera! 1985 N.C. Wildflower of the Year.
