I bought this beautiful fern two years ago. It has always returned the following spring more beautiful than the year before. I live in Chattanooga, Tn and it is 18-20 inches tall on 6/8/2015. Getting bigger but invasive it doesn't seem to be. Love it. Sorry you have had bad luck with your attempts to grow this beauty.

Over the last 6 or so years, I have tried a total of 14 of these plants from a variety of sources. Many have flourished during the summer but none of them has survived the winter in spite of being described as hardy to zone 4. I'm successfully growing some pretty fussy ferns, so I'm wondering if Japanese beech fern is not as hardy as claimed.

An update. Last year I bought 3 more JBF's, this time from Big Dipper. DOA. They replaced them, but the ferns haven't yet appeared this spring. Meanwhile, I got one from Venero, a local nursery (attempt # 24, I think--talk about stubborn! and foolish). And it's back! And spreading! Obviously the source is critical.

Well, I divided them and they did well during the summer and then didn't return. Now (June 2013) ... read more
