Matteuccia struthiopteris has the apt common name of Ostrich Fern because its fronds resemble the elegantly graceful plumes of the ostrich. Native to North America, once established, this Zone 3 fern performs well under conditions that few garden plants prefer, while offering a culinary spring treat to boot. Ostrich ferns in the wild thrive in rich moist soil in part to full shade, yet they are one of the best performing ferns in our area. They tolerate our drier alkaline clay soil and with a little love will colonize an area with a northern exposure that few plants, much less ferns, will enjoy. Better still, they survive with benign neglect: no pruning and the deer and rabbits seem to leave them alone. If you have a difficult shaded area on the north side of your house, this plant will take that spot from barren to lush in a few years’ time.
When planting ostrich ferns, choose a site that will shelter the delicate fronds from burning sun and the strongest winds. It’s also a good idea to prepare the bed with an addition of sphagnum peat and compost. This will lighten the texture, provide nutrients and improve water holding capacity. In future years, a nice topdressing of compost and an occasional feeding will keep them happy. Plant them 18 to 24’’ apart, making sure to keep the crown just above the soil level, mulch lightly to hold moisture and prevent weeds and water in well. They will need regular water, especially in the first season, during which they should never be allowed to dry out. After they are established, they will survive with consistent but less generous amounts of water, while still appreciating a little extra during periods of drought. The first year or two they will work hardest on establishing a strong root system, spreading underground by rhizome. The fronds may appear shorter than the expected 36 to 48 inches and a little sparse. Don’t worry, in a few years’ time, your patience will be rewarded with a lovely soft colony of lush, almost tropical looking ferns. (Ostrich ferns can be feisty in wetter climates, but our dry conditions limit their ability to spread more than we want them to.)
They provide a graceful backdrop for other shade loving plants such as Dicentra and Hosta. It’s also fun to mix in early spring woodland plants that go dormant for the summer such as Dodecatheon, known commonly as Shooting Star. Although the leaf fronds die to the ground in autumn, once the ferns reach maturity, they will produce shorter, fertile spore-producing fronds which remain standing attractively through the winter.
Historically used by Native Americans, fiddleheads are a treasured wild forage food which appears fleetingly in restaurants and farmers’ markets in the spring. Once your ferns have established a healthy colony, you too can harvest the early unfurled leaves. Remembering to never take more than half of the shoots from a crown and only the early sterile leaf shoots, the fiddleheads must be tightly coiled at harvest, and must be washed and husked of their brown papery covering, then fully cooked before being consumed. When steamed for 10-12 minutes, they are reminiscent of asparagus. I have also boiled and pickled them successfully, which is an easy way to preserve them for later. They are especially tasty when boiled for 15 minutes then drained and quickly sautéed in bacon drippings with a little garlic. They can also be served cold on a salad by boiling them and chilling in an ice bath. A quick Google search will return lots of recipe ideas but, however you choose to eat them, make sure that you are eating Matteuccia struthiopteris and not a similar looking fiddlehead.
Even if they never make it into your kitchen, ostrich ferns are a beautiful plant for a difficult location in your garden.
