Spiderwort

Description:

Virginia spiderwort is a large but dainty perennial to 3 ft. with long, bright-green, narrow leaves. The thick clump of slender, branched stalks are topped by groups of blue or purplish, three-petaled flowers up to 2 in. across. Spiderwort flowers close by mid-day and last only one day. Blue-violet (sometimes white) flowers with showy, yellow stamens in a terminal cluster above a pair of long, narrow, leaf-like bracts. Spiderworts are so named because the angular leaf arrangement suggests a squatting spider. The flowers open only in the morning; the petals then wilt and turn to a jelly-like fluid. Each hair on the stamens of this showy spiderwort consists of a chain of thin-walled cells; the hairs are a favorite subject for microscopic examination in biology classes because the flowing cytoplasm and nucleus can be seen easily. Other spiderworts with similar structure are Zigzag Spiderwort (T. subaspera), found from Virginia south to Florida and west to Missouri and Illinois, with blue flowers and a zigzag stem to 3 feet (90 cm) high; Ohio Spiderwort or Bluejacket (T. ohiensis), occurring from Massachusetts to Florida and throughout the Midwest, with rose to blue flowers and whitish bloom on the hairless stem and leaves; and Hairy-stemmed Spiderwort (T. hirsuticaulis), a hairy plant with light blue flowers, found from North Carolina south to Florida and west to Texas.
