My husband and I are in the early stages of planning a trip to the Czech Republic, Hungary and possibly Berlin.  Can anyone suggest any gardens I should visit?  Like most NARGS members I'm pretty much a plantaholic so perennial gardens and woodland gardens are also fair game.  I'm not much of a tree person so I don't have much interest in arboretums unless they have a lot of interesting understory plants.  

My husband isn't much interested in gardening so I probably won't be able to devote more than a couple of days to garden visits.

I will be cross posting this message on the SRCG forum.

Thanks for any suggestions.
