Hi Gattina, they have an eventual height and spread of about 5 ft, they're frost hardy down to about minus 5c, they like a humous rich, fairly fertile, well drained,but not dry soil, in full sun or part shade, they should be alright in very large tubs, I say very large because they resent their roots being disturbed, and they're not very keen on being pruned either, so keep pruning to a minimum, they're pruning group 1 or 8, hope this has helped, Derek.

Thank you so much, Derek - very useful. Do they care much about soil pH?

Hi Gattina, they don't seem to be too concerned about ph, slightly alkaline to slightly acid is fine, Derek.
