These dahlias have fully double blooms that bear a striking resemblance to water lilies. The ray petals are somewhat sparse when compared with most varieties. The petals are either flat or slightly curved along their length, which makes the flowers appear shallower than the blooms of other dahlias. Blooms have no visible central disc. Waterlily dahlias are superb for adding visual interest to gardens. Many varieties have been bred to have long, sturdy stems, so they're great as cut flowers. They can create a stunning sight in a vase or afloat in a shallow bowl of water.
