Crazy (For) Ferns

Athyrium niponicum var. pictum  ‘Applecourt’

Who would dare find ferns boring?  Ferns are some of the craziest and most bodacious plants you’ll ever grow!  You just need an idea of which ones to choose.

I enjoy all ferns, to be perfectly honest.  Even the relatively ‘plain Jane’ native Christmas ferns grow with a certain peaceful confidence that I admire.

~

Polystichum acrostichoides, our native Christmas fern, earned its name because it remains green and beautiful past Christmas and into the winter months. This is a very hardy (zones 3-9), dependable fern that can tolerate a fair amount of sun, once established, and will survive a our hot, dry summers.

~

And I am sure that there are those fern lovers who prefer these for their neat, regular, evenly green fronds.

~

Sensitive fern. Onoclea sensibilis, peeks out from around a clump of native Mayapples.  This deciduous fern is very sensitive to cold weather, and dies back each autumn with the first frost.  Not to worry, because each year it spreads and gets a bit better in the garden.

~

And that is all fine, but I am partial to ferns with interesting colors and forms.  I enjoy ferns that are a bit variable from frond to frond and plant to plant; full of surprises, you might say!

~

The Japanese painted ferns fill the bill on both counts.  A hybrid of the ‘Lady Ferns,’ it interbreeds with other ferns fairly easily to produce some very interesting color patterns and beautifully ruffled and crested fronds.

Athyrium filix-femina ‘Lady in Red’

~

Growing from just a few inches to more than several feet tall, these wonderfully surprising ferns can fill many different garden niches.

~

~

There are lots of crazy ferns on the market these days.  There are ruffled ferns, footed ferns, staghorn ferns, hart’s tongue ferns, and even a hybrid named A. ‘Godzilla.’

I found and planted A. ‘Godzilla’ last summer, and I’m keeping a close eye on it.   It has not yet grown into its gargantuan potential.  It’s still sinking its roots and trying to feel at home in the garden.

But believe, me, when it does begin to grow crazy-big, I’ll post a photo for you.

Reliable Beauty: Ferns

~

Once the first few fronds of our hardy ferns poke through the warming soil, and begin to unfurl themselves, I finally trust the change of season to spring.  Tight fiddleheads are appearing in pots and beds, under shrubs, and along the bank, and we always celebrate their appearance.

Emerging fronds show up so subtly; one might not even notice them at first.

~

Japanese painted fern emerges deep red, and lightens to show some green with silver markings as the season progresses.

~

Especially those coming along under larger plants, or in secluded corners of the garden, may escape my notice until I go in search of them.  But like a child hunting Easter eggs, I make my rounds of the garden in search of my favorite ferns, re-emerging after their winter’s rest.

Christmas ferns emerge among Hellebores in our back garden.

Some hardy ferns remain evergreen.  The Christmas fern, Polystichum acrostichoides; holly fern, Cyrtomium falcatum; and our Autumn Brilliance fern, Dryopteris erythrosora ‘Brilliance’,  maintain a presence through the winter.  They are growing a bit raggedy by April and I sometimes cut off their old fronds as they break or fall.  But you never lose track of them.

~

D. ‘Brilliance’ emerges a beautiful copper, but its fronds eventually fade to medium green.

While D. ‘Brilliance’ is a hybrid, the Christmas fern is one of our most common native ferns.  D. ‘Brilliance’ can be found easily in most garden centers each spring.  It can be a little harder to locate starts of the Christmas fern, however.  This spring I found them, bare root, at a big-box store and stocked up.  I have about a dozen of them started in little pots, ready to plant out when I find a spare hour for planting.

Holly fern is also easy to find at garden centers and big box stores either bare root in late winter, or already growing in a pot in the spring.

These are all clumping ferns.  While they will grow a bit wider and taller over the years, they won’t go wandering through your garden without your assistance.

Like other perennials, ferns have their own sequence for when they first appear each spring.  One of the earliest ferns to emerge is the beautiful hybrid Athyrium niponicum, ‘Pictum.’ 

Known as the Japanese painted fern, there are now several beautiful hybrids with various color patterns and with beautifully curled and divided fronds.  These are such a dark shade of burgundy as they emerge, you might not even notice their fiddleheads at first.

~

~

I keep a clump growing in a low trough by the kitchen door, and watch it daily each spring, waiting for the first signs of life.  These fronds have often fallen away by early spring, and unless you remember where they are planted, they will surprise you as they unfold.

The Athyriums, known as ‘lady ferns,’ may spread year by year.  They have good manners, however.  Chances are you will divide them before they move beyond where you want them to grow.  I particularly enjoy the hybrid A. ‘Ghost,’ which is a lovely silver grey.

There are many beautiful ferns that grow well in coastal Virginia.  We have an interesting selection of native ferns here, and we grow several of them.  Maidenhair fern, royal fern, cinnamon fern and sensitive fern are a few easily grown natives.

But we also collect several imported ferns, hybrids and cultivars, as well.  Can one grow too many ferns?

~

Although ferns generally appreciate at least partial shade and consistently moist soil, they are much tougher than they appear.  Once established, many varieties can stand up to some sun and survive, with mulch and a little supplemental water, during drought.

Do your homework before you plant, however, and keep in mind the gardener’s mantra, “Right plant, right place.”

~

~

It is easy to grow most ferns, if only you site them to meet their needs.  Given good soil, a bit of shade, and sufficient moisture, they happily grow on year after year.  In fact, if they are sited in their ‘happy place,’ you will see new ferns crop up nearby from either spore or spreading.

If a fern seems to be struggling, then simply dig it up and move it.  Often, a fern will go into dormancy during summer’s heat in order to survive if it is getting too dry or too much sun.

I tend to buy the smallest pots of ferns that I can find.  In  our wooded garden, with so many roots everywhere, I like to start ferns small and let them grow and find their own way among the already established plant community.  This nearly always works. 

~

~

It is also kind to build a raised bed for your fern installation, as long as you keep it hydrated.  I also grow some in pots, and keep them going year to year.

~

~

Hardy ferns can stay outside in their pots all winter.  I bring the tender ferns in to the house each fall and set them out again when the weather has settled in spring.

Ferns are beautiful just by themselves, and I am cultivating a collection of them on a steep bank in the shade in our back garden.  But they also add a graceful note when grow with bulbs and perennials or under shrubs.  Medium sized ferns are a good ‘shoes and socks’ ground cover in the front of a shrub border and under trees.

~

~

Ferns lend a peacefulness and serenity to the garden.  These easy plants hold the soil against erosion, require minimal fuss or maintenance, and have a long season of beauty.  Deer and rabbits rarely touch them.

~

~

They make me happy, and I keep planting more with each passing year.
