Adenium Blooming in Autumn

They do this every year, at least one will spend the summer just sitting there while all your other adeniums are busy putting on their annual floral show. Then the literal late-bloomer will start developing buds when it starts getting cold at night. If your plant does that, bring it inside immediately--these buds are extremely sensitive to temperatures below 16C. Put it in the sunniest, warmest room in your abode and keep watering it with very weak fertilizer every week.

There is nothing else in this post, just more pictures of this autumn inflorescence. Over time, usually after about a week indoors, the flowers will develop brown spots as they slowly die and fall off. You can try hand-pollinating them, just for kicks. No success here so good luck with that.
