This clump of Adenium oleifolium has come out of dormancy and is leafing out quickly.

Will the caudex's merge as it ages? I would think it would get crowded. Wonder if they will twist to each other. I am guessing that you would not bonsai this on a small scale you would just let it grow. Interesting idea

I read in Dr. Dimmit's article that this species is the smallest in the genus. And that "the caudex is subterranean, and the stems are scarcely succulent and rarely reach a foot tall". A. oleifolium

Pachy, have they produced flowers yet?

crystalview, Rainbow, sorry for the delay in responding. It's been a busy week at work for me.

crystalview, I do think in time the caudices of all five will fuse together. However this is a really slow growing species and it will be a long time before that happens. I plan on moving up to larger pots as the plants grow, so crowding won't be a problem.

Rainbow, your right, this is a dwarf species. I've gotten flowers from my A. boehmianum, A. swazicum, A. multiflorum, A. crispum, A. sp. Tanzania, A. somalense, A. arabicum and A. obesum plants, but I have not gotten flowers from this species or my A. socotranum and A. dhofarense plants. These three are really slow growing species, so I think it will be a while before I see flowers.

Wow, Pachypode! It will be a real treat to eventually see your entire collection and get periodic updates of their development.

Do you have all the adenium species and subspecies in your collection?

Rainbow, Of the types known, I'm only missing the northern/western form of Adenium obesum. It is possible that more forms (species?) are waiting to be identified.
