Here we have an individual listing of a primary cross between two giants. Surprisingly, there does not seem to be any fragrance from the hangianum present.

This listing is for a two-growth plant in a 5" container with sphagnum moss. The flowers are open as of 8/24/23, and with the summer heat may only last another two weeks or so. The second growth is developing and should flower next season. Note the tape being used to train the foliage upright as it was flopping over (a very common trait with these types of hybrids when the foliage is long).
