Buddleja alternifolia
 

Hi all,

Can anyone give me some clues about how to look after my new 18" Buddleja
alternifolia, please?

I'm especially confused about the fact that it's tied to a thin stake,
looking much more like, say, a Russian vine than the B.davidiis that I'm
used to. I assume I should leave the stake when I plant it out - will I
need to do any pruning or staking in the near future?

thank you!

p.s. for bonus points, what does the name 'alternifolia' mean?
