9:15AM Stephanie Cohen
Author, Gardener and Perennial Diva

Cutting Edge Perennials, No Bandages Provided!

The Diva loves new plants and will show you what's new in non-natives and natives. The word “new” does not necessarily mean better. It should just mean different flower size, color of flower or  leaf, immunity to pests and diseases, and even lower maintenance. Some good plants slip through the cracks and others are worthy candidates for the compost pile. Be prepared as the Diva does not mince words  and the dirt will fly during this presentation!
