Hardy water lily pond plants, once established in your water garden, will reward you with many flowers throughout the summer months. Hardy water lilies bloom continuously from May thru September and then enjoy a slumber through the winter to return each spring with blossoms. Hardy water lilies are shipped to you as mature, bare-root, growing water lilies.  Plant hardy white water lilies with red water lilies in media soil and mix with floating, lavender-blue hyacinths for an "ooh" and "ahh" patriotic theme.
