Have two of these and they are in their third year in pots on my shaded deck. (2010). Fronds are nearly 36". Glossy, and the color variation with new growth is spetacular. Still producing new fronds in mid August 2010. Can benefit from a bit more bright light and early morning sun than some ferns. Slower both seasons to produce new fronds and while evergreen, it looks best to cut off damaged ones. Just be patient and don't cut until new fronds have emerged.

I live in southern california (South Orange County 92679) in a neighborhood where the summer temperatures are 90 -100 degrees three months per year. We get a frost once per year or so in the winter. I planted an autumn fern under a large oak tree that is doing great! It gets some filtered morning sunlight but is in shade the rest of the day. The orange colored new growth is strikingly beautiful on 24" stalks. A gorgeous fern for a shaded area in a warm climate.

This strong, Japanese Shield Fern grows well in our sub-tropical area in Angelina National Forest.
It grows along roadside under pine, oak, and blackjack tree canapies.
I potted same and it is disease, fungi, and insect resistent.
Thanks for the nice photo.
