Best dark-leaved sambucus to grow?

I ve got one that I split a couple of years ago, so now I have two.
Really dark leaves, one grows in sun/semi shade the other grows well in shade by my tree ferns.

I trim them back just for shape as and when I need too. Mainly early spring but also through out the year if required.

You can see one of them Andrew on one of my latest garden pics of my front garden. It is in the left hand border just behind the badger.

Mine is also in the shade for most of the day, and it's great. Sambucus nigra 'Black Beauty'. There's another one with lacy leaves, but I preferred this one. It has pink clusters of flowers. I trim it in early spring, if it needs it.

I had a Nigra 'Black Beauty' in another house and I loved it.

I have "Black Beauty", with normal, elderberry shaped foliage, and also "Black Lace" (the lacier-leafed variety. Both grow in semi-shade. I trim very seldom, and really like the flowers and dark berries.
