Powdery Mildew: The Bane of Beebalm
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.

‘Lady Francis’ Ivy Wakes Up A Shady Patch
On a recently trip to the Ohio State University Horticultural Gardens in Columbus, I discovered ‘Lady Frances’, a relatively tame miniature ivy. The American Ivy Society classifies Hedera helix ‘Lady Frances’ as non-invasive, and it received the first “Ivy of the Year” award in 2001. It grows slowly and works as a ground cover or topiary […]

Northern Maidenhair Fern Appear Delicate But Grow Tough
Their leaves (called “fronds”) appear delicate, but maidenhair ferns (Adiantum spp.) are reliable long-lived perennials. Northern maidenhair (A. pedatum) thrives in most gardens within USDA zones 3-8, while the Southern counterpart, (A. capillus-veneris), predominates in warmer USDA 7-10. Unfortunately, planting of maidenhairs are not utilized in the Southern Appalachian gardens (USDA zones 6-8). Fronds average 18-24 inches in […]

Artillery fungus is a wood-rotting organism living in the mulch around your home foundation. The fungus shoots its sticky, black spore masses as far as 20 feet out away. The tar spots adhere […]
