Pot suggestion for an odd Bougainvillea

I'm having trouble envisioning a suitable pot for this tree. Does anyone have any suggestions?

Thanks very much for your help - Chris



better look at the base:

Can you give us the dimensions please, Chris. It's bouncing down rain today so I feel a few hours virting coming on.

Hello Fiona - once the tree is repotted at its new angle, and when it fills back in again, it will be about 16" tall x 18" wide. The widest part of the nebari is 4 1/2", and the base of the trunk is about 2 1/2". I also should have mentioned in the original message that the flowers are a deep pink color.

Hi Chris.
Here an odd one from me.
How about something in this direction for a pot?

I am curious about Fioana's suggestions.

Hi, forgot to mention what is the odd one in the pot.
30 year old Hydrangea Petiolaris.

Thank you, Sunip - I definitely will give that some thought. I too would like to hear Fiona's idea...I guess I'll have to wait until it next rains in Scotland...probably years from now, I imagine...
