Here are the subspecies growing in British Columbia: Trachycarpus fortunei is the regular Windmill palm that is the only Trachycarpus known to the general public on British Columbia's coast. Trachycarpus wagnerianus ("Waggie") is a form of the windmill palm that is more attractive and * tolerant of high winds *. Fronds are jaunty and smaller. If someone sees a Waggie and a T. fortunei, he will prefer the Waggie. T. wagnerianus X fortunei is a hybris palm tree. There is one in North Vancouver and another in Victoria, BC. Fronds larger than Waggie but the Waggie stiffness is preserved. Interesting palm. Trachycarpus takil is larger in all its parts than T. fortunei. It is a little more cold hardy than a regular Windmill palm not that it really matters when you live in Victoria or Tofino, BC. The rare Trachycarpus princeps is only in seedling form in BC. It is new and rare. This is the most sought after palm in British Columbia as palm enthusiasts can't wait to test it. Trachycarpus martianus is a more delicate and exotic looking palm but it is borderline for SW BC. People on Saltspring and Victoria can grow it but be cautious of coldest winter spells when it may require protection just like a Tasmanian tree fern. Trachycarpus martianus x fortunei. One specimen in Victoria growing well with zero protection like T. fortunei. Fronds have a more waxy look. More leaflets that T. fortunei. Leaves more wind-tolerant. Trachycarpus nanus: New to BC as seedlings. Probably the cold hardiest of Trachys but they are short palms like Sabal minor. Grow them where T fortunei is borderline. Trachycarpus lastisectus and oreophilius are not tested yet. T. latisectus has large fronds. That's why some BC palm enthusiasts want to try them.
