Drosera capillaris
Drosera capillaris is the most-frequently encountered species of the genus in the South in moist habitats that can support carnivorous plants, especially in fire-maintained pinelands. Plants can be quite small, or form surprisingly large and robust rosettes (to 12 cm broad) in some places along the Gulf Coast. It is disjunct from the Coastal Plain to Arkansas and Tennessee, as are several other species from coastal wetland habitats. Since the leaf blades of D. capillaris can be somewhat orbiculate, it may be confused with the much more northern D. rotundifolia, which grows more typically in sphagnum (although in its northern range it often grows on moist sand substrates), has adnate stipules, white flowers, and forms hibernaculae.
Drosera capillaris is easy to grow, often behaving as an annual.
