Yes, there are many water garden plants that do well in the shade! Here are a few.
Although the plants I have listed above will do well in the shade, they may not bloom as profusely as they might with additional sunlight. However, these plants will give you a beautiful shade garden with some color and plenty of texture and variety to spice up any shady area in your water garden feature
Some waterlilies are tolerant of low-light conditions. Here is a list of waterlilies that will bloom in part- shade ponds and water gardens:
Some Nelumbo Lotus will grow and bloom with as little as four-five hours of sunlight although not many flowers will be produced.
Some other plants that will tolerate a shady water garden setting are Impatiens, Compact Papyrus, Ferns, Joseph's Coat, Chinese Lizard's Tail, Coleus and Blue Flag Iris. Although the Blue Flag Iris won't bloom as much as it would in the sun, the sword like foliage will stay green throughout the summer. Enjoy!
