Ferns

Tagged as: Ferns

Most ferns are easy to grow as long as their cultural requirements are met.  The majority of them grow in shade or dappled shade, though a few grow in sun.  Some ferns are evergreen, while others lose their leaves in fall.  The leaves of ferns are called fronds, and the stalks of the fronds are called stipes.  Ferns lack flowers, fruits, and seeds, but reproduce by way of spores.  Sori are clusters of spore-bearing structures on the backsides of the fronds.  Some fronds are fertile, meaning spores are borne on them, while others are sterile and do not bear spores.

8.  Walking fern (Camptosorus rhizophyllus) – This small native plant loves alkaline, shady conditions and is a good choice for rock gardens.  It was named for its ability to form plantlets at the tips of its fronds, which are 4 to 8 inches long. Walking fern

9.  Golden-Scale Male Fern (Dryopteris affinis) – This semi-evergreen fern has 2 to 3-foot long erect fronds.  It’s easy to grow and is highly adaptable.  It can tolerate some sun, but prefers shade.  The plant forms multiple crowns which should be separated.  It can be easily propagated by spores.  It is native to Europe and Asia.

14.  Adder’s tongue (Ophioglossum vulgatum) – This small fern (4 to 16 inches) is not hardy in the northern Midwest, but can be grown in moist soil as an annual (hardiness zone 7-9).  It is difficult to grow.

15.  Cinnamon fern (Osmunda cinnamomea) – This 2½ to 5 foot-long, erect native fern is very hardy and easy to grow.  It is named for the bright cinnamon-colored fertile fronds which die early in the summer.  This plant prefers moist, acidic soil.

16.  Interrupted Fern (Osmunda claytonia) – This 2 to 4-foot tall native fern gets its name from the brown fertile leaflets, which "interrupt" the green sterile leaflets on the larger fronds. It does best in moist, acidic woods.

17.  Royal Fern (Osmunda regalis) – This easy to grow, medium to large native fern grows well in moderate light in moist gardens.  The fronds are 2 to 5 feet long with smooth margins.  New growth is sometimes reddish or purple, but turns green with age, yellow in autumn, and brown in winter.

18.  Christmas Fern (Polystichum acrostichoides) – The 1 to 2-foot long, arching, evergreen fronds of Christmas fern were used by early European settlers for Christmas decorations.  This North American native prefers moist soil, but survives in dry soil.  It is good for planting on slopes to prevent erosion.

19.  Japanese Holly Fern (Polystichum polyblepharum) – This fern has 1 to 2-foot long, arching, evergreen fronds.  The species name means many eyelashes because of scales on stipes and leaflets.  It’s easy to grow, native to Japan and Korea, and likes consistent moisture and shade.  Young fronds are yellow in spring.
