Other names and notes
(Indianhemp) The Dogbanes are plants with a milky juice, short bell-shaped flowers with five lobes, widely branched at the top with the flowers in clusters. The plant likes to grow in thickets, usually three to six feet in height. The 2 to 4 inch leaves are opposite, oblong to ovate with the lower ones rounded at the base and stalked. The Dogbanes have five lobed flowers, bell or tubular shaped. Here we have small tubular flowers (1/8 to 1/4”) white to greenish white, with erect lobes, clustered at the end of branches. Seed pods are in pairs, are very thin and long - up to 8 inches, which when split open release many seeds, each with a tuff of long white hairs at the top, resembling Milkweed. Juice is milky The seeds form in long, thin pods and when released have white filaments attached for easy transport by air currents. The leaves turn a brilliant yellow in the fall. The Upland Garden in prior years had many more of these plants than are resident now. Indianhemp requires cutting of stems in the fall or burning to stimulate vigorous spring growth.

Below: In the autumn, Prairie Dogbane can make a colorful field when the leaves turn a brilliant yellow: These photos from 1999 show a hillside in the Upland Garden in early October 1999 when the plant was more massed than it is today.

Notes: This plant is indigenous to the Garden area. Eloise Butler catalogued it in her index file of plants in the early Garden. Native to most counties in Minnesota except for a scattered few in south central and absent in the Arrowhead. This is one of the few plants that is native throughout the United States and all Canadian Provinces except the far north. For more notes and lore click here- More
