Milk 'n Cookies boneset is derived from a north American native plant. Its name refers to the milky white flower heads that appear in late summer juxtaposed against its striking chocolate-maroon foliage. It grows to about 3 feet in height and 2 feet wide in optimal conditions.

Milk 'n Cookies prefers rich, consistently moist but well-drained soil and would be well-suited to rain gardens and pond edges. It also makes a wonderful plant for a mixed border blending especially well with native plants such as grasses. The flowers are attractive to birds and pollinators such as bees and butterflies. The flower heads can be retained for winter for both their visual interest but also for food and shelter for wildlife.
