Radially symmetrical flowers with 3 petals and 6 stamens varying in color from blue to rose. Uses: Spiderworts have been used to detect air pollutants, including radioactive particles, as significant exposure to such chemicals causes the anther filaments to change from blue to pink. MA; Cape Cod region. The solitary basal leaves of puttyroot (Aplectrum hymale) and crane-fly orchid (Tipularia discolor) are easily located from November into early spring. They have an unusual lifestyle, similar to that of another orchid, Puttyroot (Aplectrum hyemale). The tiny seeds (with very small nutrient reserves) require specific fungi for both seed germination and seedling growth. Also, by reflecting sunlight, the densely hairy leaves remain relatively cool, which in turn reduces evaporative water loss from the leaf surface. In the Blue Ridge there are about fifty native orchid species. For this reason, they are sometimes called winter leaf or hibernal orchids, but I think of them as winter orchids. Tradescantia hirsuticaulis Small hairy spiderwort. Last week's Nature Journal about "winter orchids" focused on puttyroot leaves. Also covers those considered historical (not seen The somewhat asymmetrical flowers of this species are pollinated by noctuid moths, the flower depositing a pollinarium (pollen mass) on either the left or right compound eye of the moth, depending on which way the column is twisted. leaf (with a purple underside) stands out in winter against the mostly grayish brown forest floor. Exact status definitions can vary from state to image, please click it to see who you will need to contact. Wildlife: White-tailed deer commonly eat the entire leaf, leaving the plant leafless until the following autumn; because such plants accumulate fewer carbohydrates, they are much less likely to flower and produce fruits that year. To reuse an in part by the National Science Foundation. Then, as the flowering stems emerge in spring, the leaves wither and disappear. The somewhat asymmetrical flowers of this species are pollinated by noctuid moths, the flower depositing a pollinarium (pollen mass) on either the left or right compound eye of the moth, depending on which way the … (Wetland indicator code: All images and text © to exist in the county by The winter leaf is its outstanding feature. The asymmetry of the bloom causes the pollinia to … State documented: documented Carbohydrates stored in the shallow-rooted corm are used to produce a new leaf in fall, and flowers, fruits, and seeds in summer. The underside of the single leaf is purple, and it does not persist until flowering. Cranefly orchid. The flowers of cranefly orchid are pollinated by night-flying moths. Both orchids have prominent bulb-shaped roots (corms) that are well adapted for energy storage. Tipularia discolor Show 2020 Western Carolina University biologist Dan Pittillo noted in an email that he is impressed by the sizeable "evolutionary leap" it required to implement a shift of this magnitude. Can you please help us? This winter leaf strategy obviously evolved as an efficient way to collect the sun's energy in rich hardwood forests when the leaf canopy overhead is absent. Contact them at

Although the plant is rather common throughout the Blue Ridge, it is inconspicuous when flowering in the shadowy woodland settings it favors. the state. evidence (herbarium specimen, photograph). Ecology: Hairy spiderwort copes with the extremely hot, dry summer environment of rock outcrops by actively growing primarily during the cooler months of late fall and spring. 2-4 in.
