Nymphaea 'King of Siam' (Water Lily) is a day-blooming aquatic perennial boasting dark green leaves, up to 8 in. wide (20 cm), flecked with brown. Floating on the surface of the water, they create a lovely backdrop for the large, very full, deep violet flowers, 6 in. across (15 cm). The stamens have been modified into petals, creating flowers that appear to have over 100 petals. Each pleasantly fragrant blossom features pointed, deep violet petals surrounding a conspicuous bouquet of golden stamens. Each flower lasts 3-4 days, opening in the morning and closing by sundown. Blooming from summer into fall, King of Siam is free-flowering, non-viviparous, and produces many flowers over a long season. King of Siam is a tropical nymphaea.
