Summer is a great time for visiting other people’s gardens, and if you like historic gardens – or historic parks or maybe even historic cemeteries – there’s a wonderful online guide that will help you find ones close to where you live or travel, including some you probably never even knew existed.

It’s called “What’s Out There” and it’s an ongoing project by The Cultural Landscape Foundation, the country’s leading non-profit devoted to historic landscapes. With it you can easily search for landscapes by location – for example “Michigan” or within so many miles of your zip code – or by landscape type – including garden/estate, botanical garden, public park, golf course, and even roof garden – or by designer, style, or the property’s name.

To find out what’s out there by you, go to http://tclf.org/landscapes and click “Advanced Search” in the list on the right. Or if you’re using a smart-phone, click the handy, GPS-enabled “What’s nearby” button to see everything within a 25-mile radius. And have fun!
