Camellia's cracking bark

[LeoMame]

Hello Bonsai people,

I come to you with a question concerning the bark of a camellia. I noticed that it's cracking in some points: I have very little experience about this species (I acquired this one couple of years ago), I was only able to see young garden plants or old specimens in bonsai exhibitions. In both cases, the bark was smooth as everything, so I was wondering if you could help me out in making sense of this. I attach some photos (also of the whole plants, which shows a nice healthy green colour) and I thank you all in advance!


this is what's under the cracking bark

Strange. However looks healthy. Why worry? Possible bark of trunk exposed to too much hot Sun? Believe these do best in partial shade.

Oh not really worried, just sharing with other camellia owners/enthusiasts to better understand the barking process of the species. At first I thought it was some kind of dieback but then again I have no clues to believe so apart from this uncanny cracking pattern which I've never seen on camellias before.
