Our ferns – 1

DEFINITION OF TERMS:

  • KEYSTONE means they are listed by National Wildlife Federation as core plants for a wildlife garden in my ecoregion (Ecoregion 8).
  • NOT QUITE NATIVE means they are slightly out of range but adjacent to NYS as determined by GoBotany and NY Flora Atlas.
  • Otherwise the plant is a NY-native or native to the area noted.

Northern maidenhair fern (Adiantum pedatum)  

Northern maidenhair is my absolute favorite. It has a beautiful circular bend to the frond that’s just gorgeous. I had seen it frequently when we were hiking in the Adirondacks and other parks, but I always thought that such a beautiful plant would be too hard to grow at home. I’ve been amazed at how well it has done even though I didn’t give it any special attention.

Maidenhair emerging in the spring

This is what it looks like in the spring as it starts to emerge.

Maidenhair fern spores

The spores are curled on the back of the pinna.

Wildlife: Cover for toads, lizards


Ebony spleenwort (Asplenium platyneuron)

Ebony spleenwort

I like the interesting architecture of the fronds and leaves. My first attempt at growing this failed, probably because of competition from surrounding plants. I tried a second plant.

Although it’s supposed to be one of the easiest of the spleenworts to grow, I haven’t had success. Both have died. When I get a chance I’ll get one more to try.


Lady fern (Athyrium filix-femina)

Lady fern

I bought this in the 2015 HGCNY plant sale and planted it under the coffee tree.


Spinulose wood fern (Dryopteris carthusiana)

Spinulose wood fern

This apparently come in along with a log I picked up at the curb to line my paths. It’s currently in front of the bayberry bushes, sticking out onto the path, so I might move it somewhere where it can thrive. It’s a nice little fern.


Goldie’s wood fern (Dryopteris goldiana)

Goldie's fern

I planted this in November 2013, and it seems to have solidly taken hold.

Fortunately, it likes alkaline soil, which we have. I’m looking forward to it getting taller.

Goldie's fern spores

I was surprised to see the relatively small sori on what will be a fairly large fern.

Deer resistance: Resistant


Marginal wood fern (Dryopteris marginalis)

Marginal wood fern

This fern has grown well for us and has stayed in one place (though I wouldn’t mind it spreading.)

Marginal wood fern spores

The sori are at the margins of the pinnules (i.e. the little bumps on the underside of the leaflets), hence the name.

Wildlife: Cover for toads, lizards


Northern oak fern (Gymnocarpium dryopteris)


Ostrich fern (Matteuccia struthiopteris var. pensylvanica)

Ostrich fern

These have been patiently spreading on the edge of my backyard woodland garden. In fact, I’ve had to define an area for them, but they seem to stay within the boundary with little trouble.

It’s so nice to know that these just come up each year, and that l can simply leave the leaves that have fallen from the trees overhead, and they’ll emerge just fine in the spring — just like in the woods! They do seem to be negatively affected by drought, though.

Ostrich fern fertile frond

This is the mature fertile frond as it looks in the fall. In the spring, it will open to release the spores.
