Gardeners' Notes:

Positive santamiller On Sep 17, 2014, santamiller from San Antonio, TX wrote:

I have had this plant in a hanging basket outside for three years. I bring it into the garage when the temps get into the mid 40s. It gets mostly shade with some filtered sun. Some of the leaf edges on new growth will burn in the hottest part of the summer but the established leaves can tolerate it. I try to keep the potting mix damp but it has gotten dry for short periods with no damage. A very unique looking plant.

I have had an Asplenium nidus planted outside for a while now, and the more recently purchased (still in a pot) Asplenium antiguum "Osaka" seems to be the more robust of the two so far.
