Here's another question ...... what hybrid of Phrag. Hanne Papow doesn't try to crawl out of the pot when it matures.
Bad News:
None, both parents of Hanne Popow (besseae & schlimii) tend to climb. The vast majority of Hanne Popow and of St Ouen (Hanne Popow x besseae) tend to climb.
There are individual clones of besseae that don't climb much, same for schlimii. Almost all batches of all besseae hybrids will have some clones that will constantly climb, and some clones that rarely send out climbing rhizomes. I think, but I have no documentation, in low light conditions I get more climbing than in high light. But even a clone that behaves nicely for years at a stretch will suddenly send out a few climbing rhizomes. It is something we just have to live with. This is one of the reasons that in spite of the vigor of many Phrag crosses, you don't see many CCM or CCE awards. It is hard to grow a large specimen, because you are always fighting the climbing tendancy.
More often than not, once a climbing rhizome & growth is a year or two old, I tend to cut them off, and root them up separate from the main plant. The older back growth in the original pot often then will send out new growths and you just have to cross your fingers and hope that this new growth doesn't climb too, (sometimes you get lucky). The new division becomes your "heir and a spare" if you like that clone.
I have tried bending and then wiring down climbing growths, it is often an excersize in futility, though sometimes it works.
Hybrids with 25% or less of besseae, where the other parent is not normally a climber, do stay in their pots better. For examble;
After-Glo and any other hybrid where one parent is Sorcerer's Apprentice.
Some clones of Phrag Jason Fisher behave nicely. Or behave for several years then send out a climber.
Phrag hybrids with a member of the Phrag caudatum group as a parent tend to behave most of the time.
I have found that kovachii hybrids are capable of climbing. My clone of Phrag Allison Strom leaps up 4 inches every new growth. So this is a problem throughout the whole range of Phrag species and hybrids.
