Interrupted Fern

Osmunda claytoniana

Interrupted Fern (Osmunda claytoniana) is a landscape plant valued for its form and structure as much as its bloom. It reaches roughly 4 ft at maturity and blooms in mid summer. Match it to full sun to part shade and keep the root zone consistently moist. One caveat: like any plant, its published range is a guideline, not a guarantee, for the specific microclimate of your yard. Given a spot that matches its light and water needs, it is a dependable, low-drama addition to the yard.
