In this episode of GardenDC: The Podcast about Mid-Atlantic Gardening, we talk with Sam Hoadley, Manager of Horticultural Research at Mt. Cuba Center, all about Ironweed (Vernonia spp.) for the Mid-Atlantic Region. The plant profile is on Night-Blooming Cereus and we share what's going on in the garden as well as some upcoming local gardening events in the What's New segment. We close out with the Last Word on Love Grows from Christy Page of Green Prints.
