No, what I referring to ( I did not give a great explanation). I have had some obesums grow a bulbous base and raised them. Underneath it was narrower and when raised it looked like a
ball on a narrow pedestal. Just not my preference.
Anucha from Thailand had posted some photos of tall pole shaped Caudex's (tree form). I believe you are correct that the Somalense's would be a good one for this with their natural growth habit.
I almost wonder if you could grow the root inside a cylinder like a straw, tube or something and use larger ones as it grows. Not sure if this would work. Somehow the root would have to be able to thicken and grow thicker at the base and slightly narrower towards the top.
