Water Lettuce (Pistia stratiotes), a floating plant that creates a natural filter in your pond while helping to combat algae and green water.  Water lettuce grows like a rosette from a single crown resembling a head of lettuce.  Each leaf may reach up to 12 inches in height and several inches wide and can reach 24 inches in diameter.  They grow best in partial shade, especially in the hotter climates and can tolerate full shade. Water Lettuce will not tolerate cold water.  It prefers water temperatures of 6o degrees and above. If you experience a late Spring freeze in your area, you should protect your Water Lettuce from the cold, by bringing it indoors during the cold spell.
