Actually, I am not looking for Oryu. Just saying that even in Japan a cutting of Oryu is very expensive. Usually, cuttings of new cultivars are double or triple the price, depending on demand and how easy to propagate they are. But Oryu is still very expensive.
The unique thing about it is that it is a white flower with a cream colour. People tried in NA and Japan to create a yellow evergreen azalea. Oryu may be one of the best attempts.
Hoshi-no-Kirameki is not Kirameki. Hoshi no Kirameki is maybe the best form of Juko. Juko is a pale colour. Karenko is then Juko with both red and purple. Byakuren is then the white base flower of Karenko, but that lost the two colour trait. Hoshi no Kirameki is the sport of Byakuren that regained the two colours.
Ah, Italian in Belgium? I saw this Italian site:
https://ilgarden.it/acidofile/azalee-rhododendron-azaleae/azalee-satsuki/
But they don't ship outside of Italy.
I have 4 Hekisui cuttings that I rooted this autumn. They are growing inside, though.
Minisatsuki may also put Hekisui or Aozora on sale, probably way larger plants.
