About plant names...

Steeplebush is native to eastern North America and northern and central Europe. It is named for its steeple-like flower clusters. Steeplebush prefers wet or seasonally wet areas and lots of sunlight. See also meadowsweet, a white or sometime pinkish relative.

Plants: 24-48" (60-121 cm) tall, composed of groups of unbranched stems topped by conical flowerheads. Stems are orange-colored at first, from dense brown hairs, becoming reddish-brown and woody later.

Leaves: Alternate, dark green, hairless, and textured on top; pale and hairy below. They are 1½-3" (3.8-7.6 cm) × ½-1¼" (1.3-3.2 cm), roughly oval shaped (elliptic to ovate), coarsely toothed, connected by short stems.

Flowers: Dense, cone-shaped panicles of pink flowers 2-6" (5-15 cm) long, each less than ¼" (6.3 mm) around, with five petals. Flowers appear from July to September.

Fruits: Pods that contain narrow seeds about ¹/₃₂" (1 mm) long.
