Description

Pale Indian Plantain is a native wildflower with striking foliage. Its natural habitat includes mesic forests, woodland edges, savannas, thickets sand dunes, stream banks, clearings, prairies, and meadows.  

Growing from seed will produce rosettes of the showy blue-green foliage the first year, however, young plant do not flower. The leaves have the appearance of being made of plastic.  The upper surface of the leaves are medium to dark green, the underside are a lighter green to white.  From the basal leaves, a central stalk with alternating leaves develops, growing to up to 9' in height.  This stem ends in the form of a flat-topped panicle of flower heads.  These flower heads are typically arranged in small clusters of 4 to 15 flower heads with tiny white flowers.  

Its flowers form in clusters that are open and branched, with heads going in all directions.  Its sturdy stems can withstand the weight of its large clusters of flowers, without bending over.  

Fertile seed can be set by cross-pollination by insects including wasps, small bees and flies.  

Insects, Diseases, and Other Plant Problems:  Its self-seeding attributes make this undesirable for smaller gardens, where it can tend to take over the landscape.
