Strong Vertical Presence of Serbian Spruce

  Serbian spruce (Picea omorika) rises as a tall spire in the urban landscape. A mature tree may reach 50 to 60 feet high and it creates a narrow footprint of 15 to 25 feet wide. Lateral branches uniquely bend downward while the growing tips sweep gracefully upward. Annual growth rate is slow at 12-15 inches. Two-thirds of the short dark green needles lay […]

Common Ditch Lilies

A native of eastern Asia, tawny daylilies (Hemerocallis fulva) are often called “ditch lilies”. You see them growing along roadsides, in back alleys, and in old gardens, often in very poor soil.

Ostrich Fern Likes It Moist And Cool

For sheer toughness ostrich fern (Matteuccia struthiopteris) handles most landscape situations (USDA hardiness zones 2-7a). Ostrich fern is commonly seen growing naturally in cool moist river bottom soils, 3-5 feet in height and spreading aggressively. Roots have a clumping rhizomatous nature. The fronds grow upright with a slightly arching form, typically to 2-3 feet in […]

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 […]

Dawn Redwood Is Back From Extinction

  Dawn redwood (Metasequoia glyptostroboides) was thought to be extinct until the mid-twentieth century. In 1948 dawn redwood was re-introduced into North America from Sichuan-Hubei Provinces in China.   Dawn redwood grows in full sun and in well-drained, compost-rich soil. The tree struggles in dry or high pH soils. Dawn redwood will tolerate standing water for a […]

‘Sunburst’ Golden St. John’s Wort

Our native golden St. John’s wort (Hypericum frondosum) deserves more planting space in U. S. gardens (USDA hardiness zones 5-8). ‘Sunburst’ is the leading cultivar and exhibits superior traits over the species. Golden St. John’s wort forms a small, dense growing deciduous shrub, noted for its showy golden yellow flowers and attractive blue-green foliage. Sunburst grows more compact […]

No Scorch ‘Verdoni’ Dwarf Hinoki Cypress

Its fan shaped gold-edged green foliage will light up almost any garden locale. It makes a great garden companion with short growing perennials, […]

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 […]
