I was going to get a larger pot and put it straight into it's final sized
pot. Is this a huge problem?


Not if you have perfect drainage, and can keep the ph of the mix slightly acid.
very large drain holes and a check on the ph every 3 months or so and a small
dressing of blood and bone spring and autum.
Is it a species or a cultivar ?
The cultivar " Shady Lady does very will in large pots.
