I have a Miltoniopsis in just about full bloom. I left the house and come back to find it smells of flowers. This is one of the joys of keeping orchids.
I have a 2 other scented orchids in spike one is about to bloom. It's going to small amazing in here soon.
If you don't have any orchids that smell get some. It's so nice.
I haven't re bloomed many fragrant orchids, but one that stands out to me is Oncidium Burgundian #2. It smells soo good and then it's very powerful and the flowers last forever I bought a miltoniopsis from the grocery store and it was very powerful as well. I can always tell when they have them in stock as soon as I walk in the store.
