The Boys Or Girls of Summer

Gardeners are looking for simple plant combinations and this photo, shot at Kingwood Center in Mansfield, Ohio, shows three easy to grow perennials, “no-brainers” as some might call them. Originally, all three plants emigrated from the prairie where each coped with hot summers without much rainfall. In the hands of modern plant breeders, each perennial has been greatly improved. All are disease and pest resistant. Some […]

‘Brigadoon’ Hypericum Wakes Up a Garden Bed

The bright chartreuse (almost golden) foliage Brigadoon St. John’s wort (Hypericum calycinum ‘Brigadoon’) can brighten up almost any dull garden spot. This Euro-Asian ground cover thrives in any well-drained soil under full to partial sunlight (USDA zones 4-7). Full sun may burn the summer foliage in zone 7. ‘Brigadoon’ grows 12 to 16 inches tall and spreads […]

Selecting The Right Ivy For Your Garden

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 […]

Easy To Grow Dahlias

According to the American Dahlia Society there are 18 classes of dahlias, from the popular small flowered dahlietta types to the large flowered dinner plate type. Dahlias hail from South of the Border, down Mexico Way, and are not reliably winter hardy north of USDA zone 7-b. Dahlias are easy to grow. They want a compost […]

Torenia (Wishbone Flower) Blooms In Part Shade

The list of summer flowering annuals for shady spots in the garden is not long. Garden impatiens (Impatiens x wallerana) is the first choice, seconded by begonias (Begonia x semperflorens-cultorum). Today, wishbone flower (T. fournieri) is now available.  Torenia blooms from spring to frost.  It is best grown in a moist, organically rich, well-drained soil and […]

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. During the Boston Tea Party, rebellious colonists utilized beebalm as a tea substitute, calling it “Oswego tea”. […]

‘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 […]

Add Hardy Begonia To Your Shade Garden

Hardy begonia (Begonia grandis) is the only species of begonia which is winter hardy in USDA zones 6-9 (zone 5 with protection). This shade-loving perennial grows 18 -24 inches high and wide, and displays a well-branched mounding habit. Foliage is medium to olive green above and reddish green with red veining beneath. Leaf shape is […]

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 […]

Growing Mountain Laurels in Your Landscape

Mountain laurel (Kalmia latifolia) is a U.S. native evergreen broadleaf shrub (USDA hardiness zone 5). Mature sizes range from 5 feet (dwarf cultivars) to 12 feet in height and with equal spread. Over the past 30 years, mountain laurels have so improved, thanks to breeding efforts of Dr. Richard Jaynes*. He has released several dozen […]
