Thank you all for the info.
Yes. I'd say it's not easy.
Big and tall... yes. But that's why I like this one.
And I know it would have to be in a pot.
Our summers are really hot. Well around 35 C. Which is hot. Problem is... not humid at all.
I received a small plant from the US in a trade, but the info I got on the internet made me overwinter it on the balcony and the temperature proved to be too low.
Elaine, last bud? You mean they're done for this year? Or they will rebloom later on?
Good luck with the propagation.
