Trachycarpus fortunei Taylor’s Form – This is the tallest, the top of the ladder, visible above the Pittosporum, is 10′, and is the fastest growing. It is reputed to be the least susceptible to freeze damage. It retains its fronds the longest before they droop. You can see them attached to a significant portion of the straight trunk. This one suffers the most wind damage in the form of hanging browned tips, but that could be just because it retains them the longest. I bought this tree, in a small, shippable size, from Plant Delights, two or three years after I planted my big guy by the house from a 5gal container. So, it is a lot faster grower having passed its older brother.
