The radially symmetrical flowers measure 2.5-5 cm in width. The bloom consists of three, bright purple, rounded and tapering petals that surround a central grouping of deep purple hairs speckled with six, bright yellow stamens. The flowers are arranged in rounded clusters atop the terminal shoot and are supported by two narrow, leaf-like bracts.
The leaves of spiderwort are relatively large, measuring up to 38 cm. in length. They are long, broad with pointed tips, channeled, and bright green with a conspicuous dark green midvein and visible parallel veins. They are densely arranged along the length of the stem
Spiderwort grows best in thickets and meadows, and along roadsides and woodland borders.
Spiderwort receives its name from the angular placements of its leaves; this arrangement suggests a squatting spider.
Spiderwort flowers are transient. The flowers only bloom in the morning, then wilt into a jelly-like substance.
The dark purple hairs found in the center of each bloom are constructed of single chains of thin-walled cells that, under microscopic analysis, clearly expose the cell nucleus.
