That's fascinating, rhizo_1 - although this plant doesn't grow outdoors in the UK I have seen it many times abroad and never noticed any fragrance. I actually have a pretty acute sense of smell so I must sniff harder next time I see one. Do you think different specimens might have a different amount of fragrance?

Thank You missingtheobvious. You nailed it. I had never seen this plant before. I have two other St. Johns Worts growing here on the property, but would not haved dreamed of the relationship.

The last one is Haworthia cooperi v ??? I have one that is the same or at least similar and it came to me as H. cooperi.... As for your sideway pictures, I would ask if you directly uploaded them from your phone as this seems to be a issue. I guess I'm just weird about my picture taking. Any picture I intend to upload here, I use my DSLR so they always are oriented correctly.

It looks like a plumb tree to me, prunus sp.
