It would probably appreciate more light to make it more robust.

Thanks! It's in front of a South facing window and it's receiving quite some light. Is there any other possible reason?

The leaf was not bent in that direction before.

As soon as it's sunny outside I will move it to the balcony.

if you could uncurl it enough to look in there.. there may be some injury.. and it stopped growth on that surface.. but the outside surface kept growing... causing the bend...

but you would think you would remember such an injury .. is there anyone else around to interrogate about such..

South facing windows get less and less light as the sun gets higher and indoors these need direct sunlight.

As a side note, never post in the Ask the yard doctor forum because folks using Garden Web cannot respond. If you can, edit your post to remove that forum.

No apparent injury on the inside.
