Ep. 45 Hydrangea Happiness with C.L. Fornari

Plants Always Win

Show Notes

For some of us, happiness is a hydrangea in full, glorious bloom.

And if you’re not yet well acquainted with these flowering shrubs, who better to learn from than The Garden Lady herself? C.L. Fornari is the author of the upcoming 2026 book Hydrangea Happiness: Planting, Pruning and Blooming, among many others. She’s also a well-known gardening radio host and podcaster, appearing over the years as a contributor on NPR’s The Cultivated Gardener, as host of GardenLine on WXTK, as co-host of the podcast Plantrama, and today as the eponymous host of The Garden Lady on several NPR stations. We get the scoop on her broadcasting career, on her founding of the Cape Cod Hydrangea Festival, and on how she planned a modern-day guide to hydrangeas that’s “more Instagram and less coffee table book.”

Dive into this interview to learn about choosing the right hydrangea for a northern garden, about the truth of acidifying your soil for those beautiful blue mophead blooms, and about finding joy in your garden and your life.
