Selecting Sustainable Roses

Sustainable roses are sturdy, attractive plants that can hold their own in a pesticide-free landscape. This program features modern, recently-introduced varieties as well as old favorites that are disease-resistant, winter hardy, easy to grow and bloom all season. Selecting Sustainable Roses delves into the core of sustainability, explains the different grades and types of roses, their growth habits and how to select the best varieties for your garden. We use the experience gained in our own sustainable rose garden as a practical model to share tips on sustainable and basic rose gardening. Be amazed at the wide choices of color, size, and fragrance that are available and will fit into any New England garden.

Cutting Edge Perennials, No Bandages Provided!

The Diva loves new plants and will show you 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!

In this program, Bill Cullina will profile some of the outstanding native perennials yet to be discovered by the gardening public.
