Kalanchoe has never bloomed in my care, and I've had this lineage for over ten years. I'm not sure if it's because they aren't getting the conditions (light or otherwise) that they want to initiate blooming or if it has to do with the particular variety I have. Similar with the Hoya, which has bloomed only once in the 8 years I've had it, and the vine with the buds was quite obvious and would have been easy to remove before they opened. To make my list complete, aloe can also bloom - my family has had this line of aloes for 30+ years, and there have been two blooms, both in my brother's old apartment which got a ton of sunlight.
Almost all plants bloom (they have to reproduce somehow in nature), so the best suggestions are plants that bloom infrequently and with easy-to-snip buds if the poster can't be around any flowers at all.
