Just sharing my E. Paul Bunyan growing experience..My E. Paul Bunyan goes very warty when it gets water stressed, looks rosy red on the edges when it feels cold and warty during our winters here in case our winter rains do not show up. Then when the warm season returns and is in some shade and if I get to water them more, they grow smooth leaves again. Somehow it is like stress oriented, like wrinkling up. It really likes the warmer temps though, that is when I get the bloom stalks and if they turn too leggy, I do my chopping in early Spring, so it has the whole summer to form the new rosettes.
some old file photos: Feb 2011
Repotted later, file photo Sept 2012
Has been overgrown and leggy in Jan 2015
Repot in late April 2015
Observing new growth on old stem in Aug 2015:
The repotted ones doing okay, some smoother leaves, some wrinkly: water coming from my other containers above it, so I guess some parts of the E. Paul Bunyan container got a bit more water:
