Ostrich fern gets its name from its unusually tall height, a full-grown plant can reach up to six feet! Very attractive addition to any shady part of the yard, will spread underground and form colonies. Does well in wet areas or near streams, and is suitable for rain gardens. Avoid windy areas, as their soil must not dry out. The spring fiddleheads of this species are known for being the tastiest of all the ferns, but must not be eaten raw.
