Latin name Rubus fruticosus
It's fascinating how the new leaves are tinged with deep red, which disappears as the leaves mature. There are some references to this plant having been called the "Holy Thorn", perhaps because the base of each thorn is blood red.
This is another of those pictures that seems to change character depending on the background. Which do you prefer?
Please, if you've got time, could you have a look at Mats Elting's pictures, I'm sure you'll enjoy them as much as I do.http://mellting.shutterchance.com/archive.php.
