Flower:

Flowers are in spike-like clusters to 6 inches long at the top of the plant, blooming from the top of the spike down. Individual flowers are about ¼ inch across with 5 white petals and numerous long stamens surrounding a center ring that is pink, yellow or orange. The long stamens give it a somewhat fuzzy look.

Leaves and stem:

Leaves are narrow, somewhat oval, to 3 inches long and ¾ inch wide, sharply toothed, hairless, with a pointed tip and a short leaf stem. The underside of the leaf is pale green. Attachment is alternate, and they tend to be densely packed along the stem. The main stem is smooth, woody and dull brown or reddish. One plant usually has multiple stems, looking like a cluster of plants

Notes:

White Meadowsweet is classified as a shrub rather than a wildflower (forb). It tends to grow in colonies. It resembles Steeplebush, but it has distinctly pink flowers. Meadowsweet is pretty easy to identify when in bloom.
