Hamburg question

Are the Old Botanical Gardens the only botanical gardens in Hamburg?

It's a googler that one...

It's a bit tricky that one, but there's the old and the new botanical garden in Hamburg, although the old part is in a better location in the inner city and it's connected to Planten un Blomen which is a really pretty park. They often have concerts, public theater and music performances there and it's definitely worth a visit.

Thanks for the replies guys - would either of you happen to know if it's the Old or the New Gardens that have the Japanese and Chinese gardens?

They both have a Japanese section but the Japanese gardens are part of the Planten un Blomen I mentioned before.
I'm going to visit them myself in two weeks, yay !
