Re: CT damage report (z7a) low temp -5F = Sabal death?
I got the daphniphyllum as a 5gal size from Broken Arrow nursery in Hamden, CT. I got it during their fall sale 2014 at a discount, kept it indoors for the winter, and planted it out spring 2015. The top buds were actually above the wire cage enclosure and seem perfectly fine. This weekend I'll remove the protection. It's sited on the north side of the house about 10 feet from the foundation, so it gets winter shade.
The citrus right now is way too close to the foundation (my mistake at planting time) and too close to other plants. It gets protection from the wall, that's why it's probably done well (the stems are definitely alive, it's just defoliated now. Last year it was killed to the ground but it grew 4 feet this past summer. If I had the space, I would plant it further away from the house and test it. I also have a poncirus 'flying dragon' that I'm sure will be more hardy. I won't cut it now.. maybe later in the spring I'll change my mind/find a new spot for it. I honestly didn't think it would survive, that's kind of why I planted it so close to the foundation.
The magnolia is an Edith bogue I got from Twombly nursery in Monroe, CT. Deer nipped the top growth in July, but the tree responded by branching out and filling out rather nicely. So the 'pruning' they did was a good thing, in the end.
BTW three of the yucca seed batches you gave me have germinated so far. The one that hasn't germinated was "[(constricta x filamentosa) x filamentosa x elata] X filamentosa x rostrata form 2" in case you are curious.
