Ferns Add Beautiful Touch
Keith Hansen
One of the simple pleasures in life is visiting preserved woodlands and forests where towering trees create quiet, shady, often damp environments. Not many plants can grow in the low light levels cast by groves of large trees. Mosses often cover the ground, and of course, the signature plant of many forests - the fern.
Ferns are survivors, living where few other plants do well. And they have been doing it for a long time, as evidenced by the abundance of fossilized specimens.
In a landscape setting, ferns make striking accents in the shady garden. While many plants are grown for their flowers, ferns are noted for their finely textured leaves and pleasing green color. Some fern varieties have fronds that are a light green, some dark green, and others with surprising colors of grey, silver, red and blue-green.
Ferns serve a great role in the landscape because they grow so well in both partial and fully shaded settings where plant selection is limited. A morning sun exposure would be better than afternoon sun which can burn the fronds of many types.
Another plus of ferns is that they grow well in damp, even wet soils where few other plants will grow. However, many ferns are sensitive to poor water quality, especially salts.
Most ferns require a rich, well-drained, moist soil with lots of organic matter. Yearly mulching with leaf mold or compost will encourage a thriving colony of ferns.
Ferns do not produce flowers, but reproduce from spores that form on the undersides of their fronds. These spore-bearing structures are often mistaken for scales or some other insects. Some ferns produce two types of fronds. One is a sterile frond with the characteristic fern-shape, and the other often appearing as a stalk with tiny beads packed together bearing the reproductive spores.
Ferns spread by underground rhizomes, some more aggressively than others. These types are easily propagated by division in early spring just as the new growth begins to show. Fall is also a good time to plant ferns so that they can become well-established prior to spring growth.
Take care not to plant aggressive spreading types in small beds where their rampant growth would be a problem and take over smaller or less vigorous garden plants. Those types of ferns are better suited for woodland settings, along streams or other areas where their spreading nature is welcome.
Some companion plants for ferns include aspidistra, columbine, liriope, caladiums, ligularia (Farfugium), Fatsia, aucuba, hosta, ajuga and hydrangeas.
Ferns for your shaded garden areas include:
(Most die back in the winter but evergreen types are noted.)
Tassle Fern (Polystichum polyblepharum) - A very handsome and attractive, evergreen fern with hairy, dark-green fronds. It does not spread, but the fronds grow larger each succeeding year. It tolerates low light conditions.
Lady Fern (Athyrium filix-femina) - This native fern looks delicate but makes a strong presence in the garden. It has finely cut fronds, and the overall form is graceful and vertical, growing about 3 feet tall. I've grown it for several years in a small shade garden, and it is not an aggressive spreader like some other ferns I've grown.
Japanese Painted Fern (Athyrium nipponicum "Pictum'') - This popular plant is readily available and no wonder. It is hardy and very pretty, sporting multicolored fronds with silvery grey fronds hints of purple and red (it's hard to describe). This deciduous fern spreads very slowly and doesn't get very tall (to 2 feet).
Wood Fern, River Fern (Thelypteris kunthii) - This is one of the most common landscape ferns of the south and no doubt you have seen it around. Long, arching, light green fronds light up dark areas with a soft texture. This decidous fern spreads quickly by rhizomes, rapidly filling in an area. It can take quite a bit of sun if provided consistent moisture.
Sensitive or Bead Fern (Onoclea sensibilis) - This native fern grows along creeks and ditches in East Texas. It gets one of its names because the light green fronds, which turn yellow to russet in the fall, are easily burned by frost. Bead fern refers to the fertile fronds which, instead bearing leaflets, have compact clusters of beadlike sori which persist through the winter, providing landscape interest and good material for dried flower arrangements. Grows rapidly and must be controlled in smaller beds, but a good choice for the right spot in the landscape with moist soil.
Christmas Fern (Polystichum acrostichoides) - an attractive, easy-to-grow southeastern native, evergreen fern. It looks similar to Boston fern with stiff, upright leaves. Grows slowly, preferring shade and a well-drained soil.
Southern Maidenhair fern (Adiantum capillus vereris) - Though this native fern appears delicate and dainty, it is very hardy and adapted to the garden. This bright green fern spreads slowly by short rhizomes, making thick colonies in the moist shade garden. A welcome addition to any landscape.
There are many other ferns, and some types have many unusual named forms. If you have shade, then there is a fern for your yard. For more information, North Carolina State University has a good online publication on ferns (http://www.ces.ncsu.edu/de-pts/hort/consumer/factsheets/hardyferns/hardyferns.html). The University of Georgia's Cooperative Extension Service also has a good Web site on ferns for both indoor and outdoor culture (http://pubs.caes.uga.edu/caespubs/pubcd/B737-w.htm).
