Spatterdock is a large, water lily-like aquatic plant with heart-shaped leaves that can float on the water’s surface or remain partially submerged. It produces distinctive round, yellow flowers that are smaller than golf balls. This plant spreads aggressively through both seed production and its large, spongy rhizomes, allowing it to establish dense colonies. While spatterdock provides valuable habitat for fish and wildlife, excessive growth can impede water flow and recreational activities. Due to its resilient nature, control often requires multiple herbicide treatments for effective management.
