Katsura tree (Cercidophyllum japonicum) is a large 50-60 feet tall tree from Japan and China. Katsura became extinct in North America during the Pleistocene Age and was re-introduced in 1862 by botanist Thomas Hogg. It is truly a beautiful tree, yet is still rarely planted. Katsura is hardy in zones 4-8. It prefers a moist well-drained, compost-rich soil […]

Posted by Hugh on March 26th, 2012
Weeping Blue Atlas Cedar (Cedrus atlantica ‘Glauca Pendula’) is “gravity prone”. This strongly weeping tree just doesn’t happen without staking in its formative years. At planting position a sturdy 12-16 foot metal or plastic stake or rod close to the trunk at planting time. The staking and tying procedure is neither complicated nor time […]

Contorted filbert (Corylus avellana ‘Contorta’), aka Harry Lauder’s walking stick, is an 8-10 foot tall shrub. It grows in average well-drained acidic or mildly alkaline soil and thrives either in full or partial (6 hours) sunlight. Contorted filbert is usually sold in a grafted form. It is also called corkscrew hazelnut because most branches, twigs and leaves display […]

Posted by Hugh on March 21st, 2012
There are so many fine redbuds (Cercis spp.) which are hardy in the Southern Appalachian region (USDA zones 6 and 7) and elsewhere. Through research and breeding efforts at the JC Raulston Arboretum in Raleigh, NC, Southeast U.S. gardeners can grow several more cultivars of our native Eastern redbud (C. canadensis and subspecies texensis) and […]

Holly Tea Olive (Osmanthus spp.) comprises a number of evergreen shrubs from Japan which are winter hardy in USDA zone 7- 9. ‘Goshiki’ (O. heterophyllus ‘Goshiki’) is a hardier compact evergreen shrub, which grows very slowly at 3-4 inches per year. It is long-lived, maturing to 5- 6 feet in height and 5 to 7 […]

Posted by Hugh on March 11th, 2012
Japanese barberry (Berberis thunbergii) is a very popular landscape shrub. Japanese barberry is indigenous to Eastern Europe and Asia and is commonly planted in USDA hardiness zones 4-8. There is justified concern over the invasive nature of Japanese barberry. A number of states have declared most barberry species (Berberis spp.) to be invasive and have […]

Posted by Hugh on March 8th, 2012
Crabgrass is an annual grassy weed which dies out around the first autumn frost. Seeds dropped last summer germinate when the soil warms up from early spring through summer. When spring soil temperatures reach 55-60 degrees (the forsythia shrub is blooming), apply a pre-emergent crabgrass preventative. These herbicides are very effective applied in late winter […]

Posted by Hugh on March 2nd, 2012
Rhododendrons (Rhododendron catawbiense) were born in the cool of the North Carolina and Tennessee mountains. Hundreds of lovely hybrids have been bred by dedicated plantsmen. Winter hardiness is rarely an issue, but rhododendrons are challenged by summer heat and disease problems in the Southern Appalachian region (USDA hardiness zones 6 and 7). Your most important decision is […]

Posted by Hugh on February 27th, 2012
A few years back my church pastor complained about the ugly load of seed pods covering the redbud branches (Cercis canadensis) on the property in the fall. My suggestion to avoid messy seed pods is to plant seedless redbud cultivars. A number of native redbud (C. canadensis) cultivars produce few to no seed pods. Let’s start with the cultivars ‘Ace of Hearts’ and sister seedling ‘Little […]
