Not palm related but I have this in my palm garden. This in my Eucalyptus Neglecta. It is a little over 6 feet tall. I planted it in march,2020 as a 3ft tree from Plant Delights nursery. It has never been protected other than good sighting.  It was un phased by a winter low of 4 degrees Fahrenheit and two weeks below freezing during the arctic blast last February. Cincinnati zone 6b.

I Know Mc Curtains get a lot of hate but I am proud of my largest one. This is mine 2 months after the arctic blast with a low of 4 degrees and full exposure to wind. No protection given to it what so ever!
