Every place we have visited in Rome has been worth the effort. Most are simply fabulous. This was the only disappointment. My recommendation: This is not a secret garden to discover in Rome. It’s a poorly maintained collection of very old trees(THEY are beautiful) and one flowerless rose garden planted in the shade. I’ve enjoyed some fabulous botanic gardens around the world. This would be a disappointment if it was a suburban Chicago park. Beyond the age of the plantings, there is nothing to offer the tourist here.
