Did you know

  • Each spiderwort flower lasts only a single day — opening in the morning and turning to a wet jelly by afternoon.
  • Spiderworts are sensitive to radiation — the stamen hairs change from blue to pink in the presence of even low-level radiation, making them used as bioindicators near nuclear sites.
  • The plant was named after John Tradescant the Elder, gardener to King Charles I, and his son John Tradescant the Younger, who collected it in colonial Virginia.
  • Spiderworts get their common name from the angled, jointed leaves that resemble a squatting spider, or possibly from the silky thread-like sap of broken stems.
  • Wandering jew (Tradescantia zebrina) and inch plant are popular houseplant relatives in the same genus.
