Nymphaea 'Black Princess' (Water Lily) is a day-blooming aquatic perennial boasting purple rounded leaves, 8 in. across (20 cm), gradually turning green as they mature. Floating on the surface of the water, they create a lovely backdrop for the striking dark red, almost black, peony shaped flowers. Each slightly fragrant blossom, up to 5-6 in. across (12-15 cm), features substantially red outer petals with nearly black inner petals, surrounding a conspicuous bouquet of yellow stamens. Each flower lasts several days, opening in the morning and closing at night. Blooming from late spring to early fall, Black Princess is free-flowering and produces many flowers over a long season. This hardy nymphaea is recommended for any water garden.
