7 " which is likely too big. I think I should have put it in a 5" or so.
I bought it summer '14 and it had like 4 leaves and I kept it in the 4 " pot it came in for a year. Repotted last summer and just grabbed a pot. I forgot it likes to be pot bound. (Unfortunately my memory has problems sometimes.
Ain't quite as it was 30 or 40 years ago.
)
I moved it to my back unused bedroom where it will be much cooler (sorta unheated) and adequate light.
