Four Landscape Shrubs That Are Early Summer Stars

Bottlebrush buckeye (Aesculus parviflora) is one of our finest early summer native flowering shrubs for sun or shady sites. It is a dense, mounded, suckering, deciduous, multi-stemmed shrub which grows 6-12 feet tall and 15-18 feet spread. It flaunts unique palmate green leaves (5-7 leaflets) and white 10-12 inch tall floral candles. The dynamic bottlebrush  […]

Queen Of The Prairie Or Meadowsweet

Q “Tall and pretty spectacular” very much describes Queen of the prairie (Filipendula rubra) (USDA hardiness zones 3 to 8). Twelve species comprise this genus of U.S. perennials (USDA hardiness zones 3-8). Best known species are meadowsweet (F. ulmaria).dropwort (F. vulgaris), both native to Europe, and queen-of-the-forest (F. occidentalis) and queen-of-the-prairie (F. rubra), both native […]

The Mountain Mints – The Pollinators’ Favorite

Mountain mints (Pycnanthemum spp.) are clump-forming native perennials. They typically grow 1-3 feet tall depending on species (USDA hardiness zones 4 – 8). About 20 species of mountain mints are found in the southeastern U.S. As their name suggests, they belong to the mint family, very evident by their square stems and aromatic leaves when […]

Growing Coneflowers

No question, coneflowers have changed greatly over the past quarter century. Varieties are now available in many color shades and plants demonstrate improved longevity. Current cultivars grow alot shorter. However, some hybrid forms have been disappointing, barely surviving  1-2 years. When choosing coneflowers, Purple Coneflower (Echinacea purpurea) is my #1 favorite for dependability (USDA hardiness […]

Growing Angel Trumpet (Brugmansia)

Angel trumpet (Brugmansia) is tropical plant native from Venezuela to Peru (USDA hardiness zones 7-b to 10). Plants are surprising hardy outdoors in zone 6-b in protected areas. This beautiful perennial/shrub, grown in tree form, reaches heights of 6-10 feet. It is a member of the Solanaceae family which includes tomato, potato, petunia, nicotiana and other great garden plants.  They’re […]

Double Take® Flowering Quince

D Flowering quince (Chaenomeles spp) is an early spring flowering shrub treasured for its brightly colored blooms (USDA hardiness zones 5-9). Old fashioned quince shrubs produced small amounts of fruits (quince) which were gathered and made into yummy jelly in the autumn kitchen. Old fashioned varieties often grew 10-12 feet tall shrubs and produced small sharp thorns which made […]

Smoketrees For Their Multi-Seasonal Appeal

Smoketree or smokebush (Cotinus coggygria) is a large shrub or small tree native from southern Europe to central China (USDA hardiness zones 5-8). Over time it typically matures to 10-15 feet high and wide. Depending on cultivar (see list below), smoketrees have oval leaves tinted in rich purple, gold, or green shades. Generally, they grow […]

Dependable Conifer Trees For Southeast U.S. Landscapes

Arizona cypress (Cupressus arizonica var. glabra) is a southwestern U.S. conifer tree that is often underplanted. Soil drainage is an absolute must! Growth rate is moderate (15 feet high after 10 years) and eventually will reach 30-50 feet at maturity. (zones 7-9). I have seen multi-year specimens thriving in zone 6b. Deodar cedar (Cedrus deodara) is […]

Some Conifers Don’t Like Summer Heat And Clay Soils

Most conifers are best grown in deep, moist, well-drained, acidic loamy soils and in full sun. In the deep South evergreen conifers are challenged by warm soils, poor soil drainage, and humidity. Humidity increases their susceptibility to diseases. Once established they are drought tolerant, but most fail in poorly drained wet soils. Many pine species […]

Zone 6 Hardy Camellias

Once upon a time, across the Southern U.S., camellias were highly prized for their showy flowers in the fall-winter landscape. What has changed is that gardeners in the Middle Atlantic and mid-Southern states can now grow them equally well. Camellias are evergreen woody shrubs native to Asia. Currently, after decades of inter-breeding with species from […]
