Yes, Fiat lives in a neighboring county close to ours here.
Fiat, as to the amaryllis, there are some with a faint fragrance, it just depends which cultivar it is. But so far those that had bloomed in my area are just the colorful ones, and not fragrant.
I have grown some orchids that are mildly fragrant:
Oncidium Sharry Baby - smells like chocolate
Zygopetalum- sweet floral scent
Maxillaria tenuifolia - smells like coconut
Phalaenopsis - so far those that have bloomed are not fragrant, but they are really pretty. Best part these blooms can last for several months..from 2 to 4 months
Paphiopedilums - these ones grow in low light, so good for indoor growing. But I do find it takes awhile for them to bloom in my area..I am thinking it is my low humidity that affects it..but such a beauty when it manages to bloom. The ones with me has no fragrance again..but as I have said I like the beauty of the blooms:
The thing with orchids, to make them bloom nicely, you have to provide that growing culture it needs. You can grow them indoors, but really needs that good combination of bright light, humidity, water, fertilizer, air circulation. But that bright light is really essential. Not direct sun, but bright light. Except for Phals and Paphs, they prefer indirect light.
I find orchids in the Oncidium Alliance easiest to grow, sometimes I deliberately make them sit in water..it is just so thirsty here. And recently I have moved them to my growcamp this summer. Their flowering really goes best in part sun/part shade. But they can be grown indoors, near a window, with due diligence in watering, and patience in waiting for the plant to grow. I get blooms during late winter to early Spring. I would encourage you to read more about the culture of whatever orchid you may want to try, they take awhile to bloom, takes a lot of patience.
I have three Hoyas: Hoya shooting star, Hoya carnosa 'Krimson Queen' and Hoya kerrii variegata. H. carnosa KQ, I have not been successful yet to make it bloom. Geez, cannot remember if the other two have a slight fragrance, sorry..but they are just both pretty when in bloom, so it does not matter at all to me.
Hoya kerrii variegata managed to bloom only when I placed it in my shady patio, but indoors I only get its leaves. Hoya shooting star, this one is happy enough to bloom indoors just by the window, as long as you make it sit in water.

As to epicacti or orchid cactus, though you can grow them indoors, it is best to have them outdoors in bright light, it can actually take a few hours of full sun as long as media is damp moist. But the blooms are just a one day or one night show. But truly pretty and showy when they manage to bloom. The ones I got have no fragrance, but their blooms are enough for me. I also find that I can leave them outdoors any season, even in winter.
Bottomline is these houseplants, need good bright light to encourage them to bloom. Fragrance will be the bonus. But I grow them more for their nice blooms.
