Re: Growing Windmill palms in zone 6?
Those are the scientific names... common names are windmill palm (Trachycarpus fortunei), miniature chusan palm (Trachycarpus wagnerianus), Kumaon Palm (Trachycarpus takil), Pindo Palm (Butia capitata) and so on. The are all trees though. The needle palm can form a truck too (I've seen them) but it takes a very long time because most of it will be underground.
The crown is where all the fronds grow out of. That's pretty much the life of the palm tree. If that rots and dies out, the whole tree goes.
