Description

This native wildflower grows in full sun to part shade in well-drained soil, typically found in swamps and wet thickets and meadows, stream banks and prairies.  Environmental conditions will dictate the plant size.  Plants situated in full sun will require more moisture than if grown in part shade.

Purple Meadow-due is dioecious, either male or female. The male plant tends to grow larger panicles than the female.  There are no petals on the male plant. The 1/3" male flower will have 4-5 deciduous sepals and as many as 15 stamens.  The filaments are slender and white, the anther pale yellow.  The female also has 4-5 deciduous sepals, up to 15 light green pistols and again no petals.   The wind will cross-pollinate the flowers.   Male flowers are showier than female flowers.

It makes a great background plant for beds.

Insects, Diseases and Other Plant Problems:  There are no serious insects or disease issues.  Occasionally, powdery mildew and rust may affect the plants' health.  Support may be necessary for taller plants.
