Does anyone love these as much as I do? Peruvian Lilies, also known as Lily of the Incas or Alstroemeria, are commonly used in floral bouquets as fillers – but I just love them by themselves. They are inexpensive, they last absolutely forever, and they are just so pretty! I have some growing in my garden (zone 7a) but have yet to see if they will overwinter – last year they made a small showing, but not enough for cut flowers.
