Ostrich Fern
The ostrich fern is one of the largest ferns native to central and northern North America. Under optimum growing conditions, the fronds grow at least 4 to 6 feet tall, and sometimes taller. The fronds are a lustrous dark green and grow from a central crown. Underground runners rapidly grow outward from the crown and spread easily into nearby areas. This fern should be planted only in large areas where it can grow freely. The fronds are deciduous and turn brown with the first fall frost. The bronze, fertile fronds stand erect over the winter. The ostrich fern is native to marshes, swamps, and shallow creeks. It grows best in a sandy, slightly acid (pH 5.5 to 6.5) soil that is high in organic matter. Keep the soil moist.
This fern thrives in areas with light shade, but can tolerate alternate sunlight if the soil is kept moist. The ostrich fern is easy to grow, but because of its height, it is most effectively used as a background plant. Plants should be set 3 feet apart to allow room for spreading.
