I honestly don't know how old it is, Cameron. I have a huge one in the ground, and a couple in pots. Thanks for the compliment. My garden really doesn't look very good for October. Usually, this is the month that everything "pops." The lack of rain and the intense heat of our summer has taken a toll on most of the tropicals. I lost a few ferns that I'd had for quite a few years. The heat was just too much.
This Bird's Nest Fern is about 8 or 9 yrs old. It's been through a couple of hail storms and our last two hot, hot summers. It's bouncing back again.
