Here's a picture of a mature palm that has produced fruits in British Columbia. Trachycarpus fortunei fruit is small and no they are not dates. Most of the content is seed.

It is not common for a Trachycarpus to curve like this specimen. I think that it gives this palm character.

Location: Victoria, BC

Time: November 2004
