buddliea in pots

I want to grow some minatures in tubs.  Given that they will normally grow anywhere, and do not have too many special requirements, what do you think will be the best growing medium for me to buy. ??  Thanks,  Mrs Bouquet

For long-term permanent planting, go for John Innes Number 3.  It has the highest soil percentage of those range of composts.

Like any pot plant, will need watering, but other than that, they should grow fine.

I had a full size budlea in a pot, grew well & flowered fine.
