Your Adenium is lush and healthy. They look like miniature frangipani (plumeira). I love Adeniums too and I have about eight varieties. Will be posting photos of them later.
hi Stilleto,I look forward to seeing them
I'm another Adenium fan, though yours definitely puts mine to shame. It's interesting that those grown from cuttings don't have the swollen base.
I think not having the swollen base might help it over winter. I keep it outside all year and the last one that had a swollen base rotted away, but this one keeps on going. Less space to rot, maybe...
