This group of tender, aquatic annuals is originally from tropical
America. They are amazing, floating plants with some varieties
producing leaves that grow up to 8 feet across. They are commonly
called Queen Victoria's Water Lily, Royal Water Lily, Amazon Water
Lily and Santa Cruz Water Lily. V. amazonica (Amazon Water Lily)
has yellowish-green, round leaves with reddish-purple undersides
that start out flat, but in time form a rim, 3 to 6 inches high.
The underside of the leaves and the outside of the rim are armored
with sharp spines. The leaves of this variety grow from 4 to 6
feet across and spread 15 to 20 feet. The double flowers of this
plant bloom at night and measure 9 to 12 inches across. They open
white eventually turning reddish-pink. This variety needs a water
temperature of 85º to 90º F. V. cruziana (Santa Cruz Water Lily)
produces leaves with violet-purple undersides. The rims are green
veined with red and they grow 5 to 8 inches high.
