In addition to the popular Oriental hellebore (H. x orientalis), four other species are hardy in the Southern Appalachian region (USDA hardiness zones 6 and 7). Christmas rose (H. niger) is the first lenten rose to bloom, often 4-6 weeks earlier if mild December weather permits. The 3 ½- inch flowers are large and showy, […]

Comments Off on The Other Lenten RosesPlanting Trees for Future Generations
Posted by Hugh on January 15th, 2011
Oaks, beeches, hickories, ginkgoes, bald cypresses, redwoods, chestnuts and others are trees that future generations inherit from previous generations. In human terms, it takes a lifetime to grow an acorn into a mighty oak. Many tree species live hundreds of years, often asking little and contributing much beauty, summer cooling shade, winter heating comfort as windbreaks, and a […]

Posted by Hugh on January 13th, 2011
Over the past ten years, deodara cedar (Cedrus deodara) has carved its niche into Southern Appalachian gardens (USDA zones 6 and 7). Three zone 6 hardy dwarf cultivars, ‘Glacier Blue’, ‘Devinely Blue’, and ‘Feelin Blue’, fit today’s smaller garden space better than most tree forms of deodara cedar that typically reach 70-80 feet in height.

Posted by Hugh on December 13th, 2010
Many rare and unusual garden plants are introduced into a garden as a thoughtful gift. Lacebark pine (Pinus bungeana) is an arboreal aristocrat which a few gardeners are privileged to own. Lacebark is a lovely 3- needle pine with exquisite exfoliating bark which becomes more attractive each succeeding year. The lacebark feature begins after 8-10 years, but it’s […]

Posted by Hugh on October 22nd, 2010
Surviving an autumn season with a heavily fruited ginkgo (Ginkgo biloba) tree is a foul smelling experience. The odorous yellow fleshy fruits ripen in October and drop onto public streets and home lawns. Several times I have witnessed the Jonesborough Tennessee Fire Department raking up fallen fruit and hosing down a sidewalk too treacherous to walk […]

Culver’s Root (Veronicastrum)
Posted by Hugh on June 28th, 2010
Midwest native Culver’s root (Veronicastrum virginicum) starts the summer flowering season in my perennial garden. It naturally grows in open woods and meadows and thrives in fertile to moist soils. However, this deep rooted plant hasn’t complain about the current dry period in the Southern Appalachian region (USDA zones 6-7). Be aware that culver’s root […]

Posted by Hugh on June 25th, 2010
Lovely agapanthus (Lily of the Nile) is native to South Africa and is not reliably hardy in the Southern Appalachian region (zones 6 – 7). Many small tubular flowers comprise each ball -shaped (umbel) flower cluster. Tall sturdy floral scapes rise 1 to 4 feet in height, blooming from late spring into late summer depending […]
Catalpa Both Loved And Hated
Posted by Hugh on June 8th, 2010
Northern catalpa or Indian cigar tree (Catalpa speciosa) has enormous presence in any landscape setting (USDA hardiness zones 4-8). Finding a 70 – 80 foot tree with a massive trunk and thick sinuous limbs is not unusual from Ohio south thru Tennessee. In summer its huge heart –shaped, pale green leaves may be easily reach […]
