You will receive 50+ Azolla Fairy Moss. Add a soft, delicate look to your water garden with fairy moss, which is also known as water fern or mosquito fern. Koi love to nibble on its soft, fuzzy foliage. Because it floats freely on the surface, shading the water as it spreads, fairy moss helps to reduce algae growth. Its colorful fall leaf display is a great bonus; the foliage darkens to purple-red at season’s end. Bring some clumps indoors to overwinter in an aquarium or pan of water to replenish the pond supply in the next season.
