Interrupted FernOsmunda claytoniana
Interrupted fern usually grows in a spreading vase form up to 3' tall, although it can grow taller if soil moisture conditions are good. It often forms colonies. Interrupted fern is well suited for wet areas along ponds, streams, water gardens or in bogs. It grows well in shaded areas of borders, woodland gardens, wild gardens, native plant gardens and rain gardens. This fern is a good soil stabilizer especially with its rapid vegetative growth. It is extremely showy in the spring and holds well through the summer.
