    I have 2 hills of these beauties in a slightly damp area of my yard, where they thrive. Here in Louisiana we refer to them as Swamp lilies or Peruvian daffs because we call our Red, White or Yellow Lycoris Spider Lilies. We have no confusion about that like other parts of USA that call these Spider Lilies. Their snow-white blooms are very fragrant. Some of the 10-year-old bulbs I started with are now the size of a baseball. I'll have to divide them soon.
