We’re nearing our 150th episode mark and for us, that has meant a lot of plants discussed. But it’s also meant a lot of great guest appearances. As you know, each episode we ask an expert from the field of horticulture to lend us their brains and weigh-in on some great plant choices for the topic at hand. We’ve had guests who made us laugh, think twice about a much-maligned perennial, or even come to realize that there are far better options out there for our gardens. Who was our funniest guest? The one that made us seriously reconsider our planting choices? Or the one who made us grip the steering wheel with white knuckles (yes—that did actually happen)? Tune in now to find out and listen to our favorite guest segments.
