Jeanna and I placed in these trees in 2008. That means it's been through 4 winters. Brad put some out two years ago but this is in one of the older trees. The winter's aren't congenial, and this summer was a bit dry for it but it's hanging in there. There has clearly been growth since spring one year ago. Last winter was preternaturally warm; if we repeat it, we may generate significant quantities of this cool epiphyte.
