Gardeners' Notes:


On Oct 19, 2015, coriaceous from ROSLINDALE, MA wrote:

Easy, adaptable, evergreen, glossy. Forms a clump that does not spread. The fronds lie flat in the winter with the weight of snow, and should be cut back in early spring before the new fronds emerge.

The common name comes from the autumnal, reddish to orange tints of the new fronds, which emerge successively all season and turn dark green as they mature. This species does nothing notable in autumn.

I really like autumn fern. It is not really, as someone else said, a "small" fern. It is at least as large as Japanese Painted fern, and its fronds lie more prostrate, so it has a larger footprint, with older fronds arching to the ground. A mature fern easily covers a 3-foot diameter. This fern seems to be very robust, and has survived in my dry-shade-clayey site where other ferns have perished. I recently planted the 'Brilliance' cultivar also, but they seem more delicate than the species. Time will tell. This fern is evergreen and can survive the most bitter cold in New Jersey, however, it can only withstand snowfall of about six-to-eight inches. If you get a foot of snow, the fronds will be plastered to the ground and will not get back up again (until new fronds emerge in spring)... read more

Bought four of these plants from Lowe's along with some other sized ferns and plantings to accent the sides of my newly built stone stairway going down a bluff to the lower level of our property.

These are absolutely striking plants and look wonderful! They are only about 1' high right now and should double in size. Looking forward to watching them grow and fill out!

Planted along with Hosta's, Male Fern, Ostrich Fern, Hydrangea, Astilbe, and Liriope.

Readily available in nurseries locally. This fern has thrived here in zone 9b.

Very pretty and colorful. I agree with sanity101: they are later to leaf out than other ferns, and they do better if kept consistently moist.


On Aug 30, 2005, sanity101 from Dublin, OH (Zone 5b) wrote:

One of the smaller ferns, it is very similar in size and habit to the Japanese Painted Fern, but with markedly different coloration. They are also significantly later to leaf out than many other ferns.

While they may be 'drought tolerant' consistent watering is instrumental in them doing well. They will not wilt or die from a spell of dryness, but they grow and spread much better if regularly watered.

I love this plant.. I've had this spot, by the back of my yard, by a fence, that has just been plain, the only place in my whole yard, that has nothing in it.. Ive tried many plants, but have never been happy with anything i have put there.. I was in teh garden center today, and on my way out, this fern caught my eye, the nice bronze color was really outstanding and i knew when i saw it, it would work great in that bare spot! When i got home, man, it made that bare spot, be a beautiful spot, now my garden belnds in, and i cant believe that i have been without this fern!! It is a great size, and the color works well against all the other green plants.. I know it will do well.. I love it

Gorgeous fern. (I actually got mine from lupinelover). :) Burgundy fronds turn greenish as they age. Can tolerate drought conditions and can reach a height of 24". They are deer resistant. If newly purchased, be sure to set plants at the same depth they were in pot, spacing at a distance equal to their mature spread. Great companion plant to hosta and coral bells.

Great plant for a shade garden. Inadverdantly I found out that it can be quite drought tolerant, too.

Absolutely beautiful, carefree woodland fern.
