If you encounter Callisia fragrans, I think it would not mind dry air, as a succulent, but as you can see, I'm in steamy AL. Basing this on the fact that nothing I've done to this plant bothers it, including coming inside for winter. AKA basket plant, I've had for several years and it blooms reliably during the first half of the year. The fragrance is strong enough to scent a small room, waft downwind in a gentle breeze outside.
People also grow Mirabilis jalapa (4'o'clocks) as permanently potted plants, especially within the exposed caudex/fat plant niche. Usually considered kind of gangly looking, this is one I keep around the yard purely for fragrance and nostalgia. Forms a huge moisture-storage tuber, after a year or two, reaching the size of a football, so can probably handle dry air. Something you'd want to confirm. Usually grown from seeds, readily found in spring seed racks (if they have those where you are.)
If there's hope of Osmanthus fragrans (fragrant olive) doing well in a pot where you are, you need this plant! Scent is strong enough to scent the entire shrub section at WM, and cause me to walk around sniffing like a hound dog to figure out where it was coming from. PIG but I would have to try a potted one if I ever happened to move back to a cooler climate where not hardy.
Is your climate the magical one where Freesia bulbs actually make their amazingly fragrant blooms? IDK...
