(aka: Osmundastrum cinnamomeum) The deciduous US native Osmunda cinnamomea can be found in every state east of the Mississippi River...and Texas and Oklahoma. The stately, upright, 3' tall clumps of osmunda thrive in moist soils but also grow well under typical garden conditions...a great large foil in woodland settings. The fertile fronds of Osmunda cinnamomea arise in spring just above the sterile foliage as phallic, cinnamon-colored spikes in the center of the clump. In moist soils, a happy clump of cinnamon fern can reach 3' tall x 3' wide, although very old clumps in ideal conditions have been known to reach 6'...one of our finest US native plants. Recent DNA work shows that Osmunda cinnamomea is only distantly related to other osmunda ferns like Osmunda regalis and some taxonomists have moved it to another genus, Osmundastrum.


Cinnamon fern requires no maintenance in the garden as long as it's planted in the proper location.

Growing Conditions:

Cinnamon fern prefers a moist to seasonally waterlogged soils. Although it is also tolerant of garden soils with average to slightly dry soils, it will not grow nearly as tall. Although typically found in light shade to dense woodlands, it will grow fine in a few hours of full sun as long as the soil moisture is good.

Garden Value:

Cinnamon fern is incredibly stunning as a specimen plant, especially when the fertile fronds arise from the center of the clump in early spring. After that, its size makes it a great textural background for other plant which emerge later.

Natural Impact:

Cinnamon fern is quite deer resistant, so is a great choice for the garden where deer pressure is a concern.
