Well....around here the only thing that grows wild (it is an invasive species) that has berries this time of year that look similar to small blueberries and has thorns is the common buckthorn Rhamnus cathartica but I would not call them sweet smelling. There are others like the alternate-leaf dogwood Cornus alternifolia that get blue berries that are similar looking to elderberries but they don't have thorns. A picture of what you are trying to ID would help immensely. FataMorgana Here is a link that might be useful: Cornus alternifolia

Beauties! I was like: ok, I'll get ONE wandering jew because everyone owns one but me. And then.. I love these colors... so why not get one each? :) They are only cuttings so won't take over the house. Yet.

Post a close up of the Cotyledon orbiculata (I believe) - the leaves look really nice! Edit: I caught a better look in the photo of your ferocactus. I have a very small cutting only and can't wait for it to get bigger.
