Among ferns, this one is relatively easy to propagate from spores, but since it can take months before a plant is big enough to go into the garden, nursery-grown containers yield quicker results. Autumn is a good time to plant ostrich ferns: Fall planting means less work watering, because the ferns will be able to take advantage of more frequent rainfall and cooler temperatures.
The emerging foliage of a fern is called a fiddlehead. For a short time in spring, the fiddleheads of the ostrich fern are edible. The flavor is nutty and earthy, a bit like broccoli rabe or asparagus. Not all fiddlehead ferns are edible, so look for a U-shaped groove on the inside of the stem and a thin, brown, papery coating to identify the edible sort. Pick just a few per plant while still small and tightly furled; they turn bitter as they mature. Before cooking, wash lightly and gently rub off the papery coating. Fiddleheads can be steamed or boiled, and are delicious sautéed in olive oil with garlic or bacon.
