Went there with wintertime around the corner, so expectations not too high.
Indeed, the open air plantlife refused to blossom. The greenhouses, one for each of the environmental types (tropical, subtropical, arid etc.) were spectacular!
All information labels are in German, but with the AI tech we have now, that shouldn't stop non-German speakers to pay this Garden a visit.
Surprisingly, entry was free of charge. At least at the time of our visit - end of October in a weekend.
Warning! Beware of rogue cacti / cactuses. I was viciously attacked by a cactus guarding the entrance of the last greenhouse of the tour.
Forgot to take pictures, but I'm sure there are plenty available already.
Highly recommend.
