Here are some pics of some of my potted palms outside for the rest of the season. There are also pics of some planted slightly damaged Trachy`s -15c 2f . I lost one needle palm has no chance it`s dead. The other two in the same enclosure with the Trachy for two years now are alive from offshoots of the main . The one Needle that I planted with the three Trachy`s last spring are demonstrating the same characteristics as the ones that lost their spears. The newest frond next to the spear is crisp and the spear looks OK. I will see if the same thing happens as last year when spear pull happened in June with the two other Needle palms. I think I will give some of my Sabal minor and Sabal louisiana a try near where I`m digging out the Needle palms. T. fortunei "RULE" they have endured the same environment and have survived beyond what my expectations were when I planted them along with the cold hardiest? Needle palm? Maybe I just got a bad cold hardy lineage of Needle palms?
