Sometimes, nurseries have plants on hand that are not listed as available. So this could be Bonica, and just not in their plant list? One rose we purchased from ARE was clearly mis-labelled, but we could not match it to anything they listed. It is a great rose, so we kept looking. Ten years later, we found its match -- a rose they NOW offer. Jeri

Hello, sorry I’m in a rush so will just say the pink variegated one looks like a type of Tradescantia, something that I wouldnt really consider as a succulent. Your English is just fine, trust me, I’m English and you write better than some I know! Perhaps add some location/zone info after your name, go to your profile and add it as your second name I think :-) Gill

Looks like an Echeveria or hybrid. It desperately needs more light. Where do you live? These don't fare well under typical indoor conditions. Those types of pots typically have a label on them. What does the label say?

Hi Embothrium, I did. I found hundreds of images and some looked somewhat similar and some looked different. That was the main reason why I decided to post this question here. I know a lot about figs but I am not that knowledgeable about plums or other stone fruit trees. I know that young trees on Citation rootstock are susceptible to this disease. It was another clue. However, I do not know. I hope it is not bacterial canker. I like this tree. It has a nice shape and produced great fruits last year and is blooming now. However, I also have a very young multi-bud pluot tree nearby and I do not want that one to get sick too.
