This is a showy plant and is easily transplanted to the domestic flower plot. Spiderwort was so named because the angular leaf arrangement suggests a squatting spider. The hairy stamens consist of a row of thin-walled cells that form a chain. They are a favorite subject for microscopic examination in biology classes because the flowing cytoplasm and nucleus can be seen easily.
All members of the Spiderwort are used extensively in scientific research to detect radiation fallout or exposure.
