Gardeners who do not want to grow exotic invasives may want to reconsider growing this in the U.S. I have seen it "in the wild" miles from any cultivation. It does have the capacity to escape and reproduce outside of cultivation and would not be an especially welcome addition to local woodlands.

There were several of these beautiful ferns growing under large trees when we purchased our house in 2002. I removed other plants that weren't happy with the shade the trees provided and the Holly Ferns have about doubled their original number. A couple get half day sun - more than I thought they'd like. They get regular moderate summer water, and with intermingled pots of various tropical looking plants (some on drip) I have a tropical looking area without needing lots of water.

The ferns do go through a less attractive period as the older fronds get so covered with spores they get brownish. However, they get so full they need a good trim once a year and away goes the brown and lots of new ones fronds appear.

I think this fern is lovely and a bit hardier than zone 8. I bought mine as an annual accent... but 3 years later it is multiplying and thriving. It's leaves are damaged by extreme cold but new growth quickly erases those blemishes, at least here. I love it.
UPDATE: I have been confused by the hardiness rating of this plant. While here and many other sources state it is zone 8, some zone 7, a few list it as 6. After several years and some very harsh zone 5 type winters (last year was the first time that my ground froze for the entire winter and temps hovered around zero F. for weeks on end) I am completely confident that the zone 6 rating is correct. It is probably only reliably evergreen in z. 8. Last winters extremes was the first time my foliage was completely killed. However, ev... read more

I have a two year old Holly Fern growing on a dry full shade bank in an urban environment. I do not give it much attention and it grows quite well.

Planted one of these several years back on the northside of my home @ 20 miles east of Atlanta (zone 7). Have never done anything to it except remove dead fronds each spring. It has slowly spread out to encompass a corner area of 4 ft. No special feeding and never watered. However it is located near a faucet so it does get drippage when I water other plants. For me, it is tough as nails.

Very slow growing - sensitive to cold weather. Okay to have as a curiousity, but not as attractive as I'd thought it would be in its third year.

I purchased 25 of what was advertised to be this product from a vendor listed on this site: Santa Rosa Gardens. It turned out to be cyrtomium fortunei (Fortune's Cold Hardy Holly Fern). This product is not as attractive and less drought tolerant. Bad experience with this vendor. We'll see about the ferns.

Easy care plant, great structure. Plants do tend to grow slowly, though.

I water this plant once a week and feed with diluted fish-

I have had several holly fern for many years. The ones that have done the best are the ones that receive more light and less attention. I have only watered them about 4 times this year (although they have had some rain). I killed several by overwatering them which led to disease.

This plant overwintered in zone 7a. It was a mild winter here and it stayed evergreen.
