James Brydon'  a popular hardy waterlily is one of my favorites.  Its unique peony-shaped blooms are a rich deep red color that grow 4-6 inches and has a spread of about 4-12 feet wide in full sun to part shade.  Its leaves open a burgundy color but change to  a medium shade of green.  Depth can be 6 - 48 inches.  It is one of the red hardy waterlilies that can tolerate more shade than the others.   Its a good choice lily for any pond small to large.
