Trachycarpus martianus – Still in a pot, about 20gal, this is my least hardy Palm. Still debating about what to do with it. All Palms increase in hardiness as the trunks increase in caliper. The trunks serve as insulation for the bud at the tree’s base. My records are thin, but I believe this is the Nepal form that ordered some years ago from Plant Delights in North Carolina. Tony says zn 8a, others aren’t so ‘generous’. Growers in Vancouver and Victoria, B.C. give it a thumbs down, they do T. latisectus also, but how big were there’s when planted? Can I find a superior micro-site?
