The American water willow is native to North America and grows in water. This durable plant is one of the few plants of its species that can survive as far north as it does. Water willow provides essential coverage for aquatic animals and is food for deer. If you live on a large lot of land and are looking to support the wildlife around you, then consider this plant in your lake. The life and death of this plant benefit the health of the water it is in. It feeds and protects the surrounding animals when it is alive, and when it decomposes, it provides valuable nutrients to the water it is in.
