Here is a photo of Hoya Sulawesi #1 just beginning to open its flowers. Sulawesi is in Indonesia, and I just read a very insightful article on palm oil in the New York Times: https://www.nytimes.com/2024/03/14/business/economy/malaysia-palm-oil-european-union.html These palm oil plantations are quickly wiping out all of the jungle diversity where Hoyas like Sulawesi #1 lives, but the story is very nuanced. Anyhow, I recommend the story if it is available to you.
