Very few turn color in autumn, and their color is generally nothing to brag about. Most ferns will not maintain their appeal through drought, or if neglected too long. Nor will they tolerate heat and wind, especially in full sun exposure.

Yet ferns are still popular for what they ‘will’ do. They provide remarkably distinctive and stylish foliage. They survive in spots that are too shady or perhaps too damp for other plants. Ferns will be quite happy in pots or planters, and some are happy to grow as houseplants. Ferns somehow avoid getting eaten by deer. If a fern gets tasted by a deer who does not know better, it will survive.

All ferns are perennial. Most are evergreen. Their foliage arches upward and outward from the terminal buds of stout rhizomes. Some ferns develop dense foliar rosettes. A few develop trunks by growing vertically instead of horizontally, and dispersing roots downward through their own decomposing fibrous rhizomes. Many ferns will get quite broad. Many are quite delicate and diminutive.

Ferns may not require too much maintenance, but the little bit of maintenance they require is somewhat important to keep them looking tidy. Old foliage should be pruned away as it is replaced by new foliage. This may be as simple as pruning away all old foliage just after new foliage develops early in spring. For some ferns, small batches of old foliage might get removed through the year.

The foliage of ferns is comprised of leaves known as ‘fronds’. With few exceptions, the fronds of ferns are intricately lobed or divided into smaller leaflets known as ‘pinnae’. (‘Pinna’ is singular for pinnae.) These pinnae are arranged on opposite sides of fibrous leafstalks known as ‘rachi’. (‘Rachis’ is singular for rachi.) Rachi are quite fibrous and tough, so should be cut close to the ground with pruning shears when they get groomed, rather than plucked.

  1. I dearly love ferns and one of my favorites here in southern Oregon is the little native licorice fern that creates a groundcover of 8 or 10 inch fronds that disappear in June and then reappear like magic in late August just when you need something fresh and green!

    1. I would not know that one if I saw it. We do not have mane specie here, and most are bit bulky things that do not die back in winter. I need to pluck their old foliage away as new foliage develops. ICK! The licorice fern sounds familiar, as if it was something I saw in a nursery. Actually, now that I looked it up, it does look familiar, as if it is something that lives on the coast. That is where the smaller ferns are here.
