It may be a bit premature posting this as we are not out of the woods yet, freezewise, but the damage from the constant cold of January, and the last cold blast in particular, has become pretty evident.
First the good news: after losing an asplenium in a bad freeze a couple years back, I replaced it with a Kyushu native species recommended by Tom. This guy seems to be doing just fine.
Likewise, Platycerium bifurcatum was able to come inside on the worst days so he's feeling fine
Cyathea medullaris is looking very rough
Cyathea cooperi, in its sheltered spot, looks like about 85% of its foliage is fried
This is the first time I've seen real damage to Dicksonia foliage. Most likely because this is in one of the more wind-exposed spots in the garden
