There are several ‘exotic’ palms to be found along the Glen.

Here is one discovery, as told  by John McGregor after a working party session on Thursday 30th June 2022:

This morning I’ve cleared the steps again and exposed a hardy fan palm at the eastern end. I suspect there was a group of three once as at the western end of the steps where there is also one still surviving of a different species. You can see the dead trunks of the other two.

Here are John’s photos:

This has been identified by Ed Dolphin as Trachycarpus fortunei or Chusan Palm.

 I think the other two stumps are actually Dicksonia tree ferns, killed by lack of light.

With a little more from Wikipedia and the RHS:

Trachycarpus fortunei, the Chinese windmill palm, windmill palm or Chusan palm, is a species of hardy evergreen palm tree in the family Arecaceae, native to parts of China, Japan, Myanmar and India.
