Thank you both for the advice.

As the Syringa is described as a semi-dwarf shrub, I think it would be fine in a large pot. I don't think the Deutzia would like it for long, though - it grows too big. You could start it off in one if you wanted to, though, and transplant it into the border after a year or two.
