Nymphaea 'Pygmaea Helvola' (Water Lily) is a miniature aquatic perennial boasting dark, purple-blotched, rounded leaves, up to 4 in. wide (10 cm). Floating on the surface of the water, they create a lovely backdrop for the cup-shaped, semi-double flowers. Each fragrant blossom, up to 2 in. across (5 cm), features upward-curving lemon-yellow petals surrounding a conspicuous bouquet of glowing golden-orange stamens. Each flower lasts several days, opening in the morning and closing at night. Blooming continuously from summer into fall, this hardy nymphaea is good for containers or small ponds.
