Have you taken the “No Ivy Pledge”? I have not. In an effort to slow defections from growing ivy, the American Ivy Society has developed a list of non-invasive cultivars. It includes several dwarf English ivy cultivars (Hedera spp.). Add a little water and fertilizer and these mini-ivies do not miss a beat. Mini- ivies […]

Beebalm (Monarda spp.) is one of our great native perennials and herbs. Native Americans used beebalm as a tea, brewing it for colds, minor bronchial and digestive complaints, and also as a poultice to soothe insect stings.

Posted by Hugh on June 4th, 2012
A decade ago garden centers sold thousands of Japanese beetle traps until somebody questioned why anyone would want to lure this summer pest into their garden.
