Do you find that pubicalyx like to grow in late summer and fall? I up-potted three of my cultivars this year (they had all gotten severely rootbound) and maybe some of it is that now they're getting more "settled" in their pots and starting to grow. But it seems to me that they are more intense growers later in the season than most species. All of mine are putting out lots of new growth right now, and forming lots of new peduncles. I hope to have some flowering going on soon. I'm attaching a photo of a vine of new leaves on my 'RHP' that are nearly black. They're all much happier with some extra "leg room" now!
