Pond plants do much more than add color to the landscape. The plants provide food and shelter for pond fish and submerged plants provide food for water fowl, add oxygen to the water and help control algae. Pond plants are available for all USDA Hardiness Zones in New York, from Zone 3 in the north to Zones 6 and 7 on Long Island.
