They hate it when it goes over 25C my plants hang down and then at night it recver, so in hot days I bring them inside, to keep it cool.
The best Hybrids so far for me is the cross with henryii, at least I get told.
This year it has 6 flowers will post later. But there is red in the pouch, so I am not longer sure if it is really the corss of both...
never seen red in a cross of this kinds.....
By< the way the first cross with macranthum is blooming and it has no red in....
