But the problem is, that saying {Sor vey} gives me the impression that we talk about a "package of trees".

Can {vey} be used for "a group of things which aren't enclosed in a box/package/whatever" ?

How would you say "a bundle of flowers" in klingon ?

Perhaps this "bundle of flowers" is bound together by a ribbon or something, but even so, it's not something being enclosed in a box.
