Looking really good Scott.
Nothing a little wilt pruf can't handle for the winter on those mags

My Blanchard is already starting to come back good after it's first winter beating.
I suspect it will be 100% after rooting in good this summer. Mine is completely exposed with zero protection from pretty much all sides though. The lil gems look great, go figure there supposed to be the weak ones. I bet those hollies will do fine too with some spray and maybe a frost cloth wrap for you. Two out of my three look not bad at all for there first year with no mulch or any protection in a cold spot in my yard exposed to north winds all winter. The one that looks crappy I planted to high, you can actually see the roots above the soil level about 1 inch oopps. It still has 65% of its leaves though.
That trachy is going to go mad this year too. Now that I look closely that one is a fair amount bigger then my first one that I planted going on it's forth summer. It's now 8 feet to the top of the new fronds, can't imagine the end of the year. So just think after 5 summers you'll be able to see it from your deck!
Nice job man!
I'll hook you up with a rostrata too if you want one when your down here this summer.
