I'm addictive about all plants I like. Orchids, ferns-esp. Platycerium, rhipsalis, cactus, Crinum and anything else in the Amaryllis family. There is a seemingly unending variety out there and the newest acquisition is always a thrill.
However, I must admit, orchids seem to be the most addictive. I have many more orchid plants than, probably, the rest put together. And, that is probably because there are more varieties of orchids than other plant families. So, more possibilities for feeding our madness.
