Is Paulownia Invasive?

Paulownia or Empress tree (Paulownia tomentosa) is a medium to large 30-50 foot tree. It is extremely fast growing, brittle wooded tree, as much as 4 feet per year.  Across the Southern Appalachian region (USDA zones 6 and 7), the large pale violet flowers of paulownia are easily visible in May, perched on branch tips.

Yellowwood Not Every Year Bloomer

  American yellowwood (Cladrastis kentukea) is a medium-sized flowering tree. In the month of May, a beautiful yellowwood tree is in bloom somewhere in the Southern Appalachian region (USDA zone 6 and 7). The 1- 1 1/2  inch white pea blossoms comprise the 8-14 inch long wisteria-like panicles which drape from branch and twig tips. Yellowwood may bloom 2 to 3 consecutive years […]

Summer Wine™: The Taming of The Ninebark

Over the past 25 years our native Eastern ninebark (Physocarpus opulifolius) has been reborn. Its overly vigorous nature has been tamed. Latest up is Summer Wine™ ninebark with small, deeply cut, wine burgundy leaves, quite different from the medium green foliage of old-fashioned ninebarks. Summer Wine is a more compact (5-6 feet in height and width) grower. Grow ninebark in […]

Select Hollies for Privacy

Ilex opaca ‘Greenleaf’ I continue to witness the overplanting of Leyland cypress (Cupressocyparis x leylandii) across the Southern Appalachian region (USDA zones 6 and 7). This is followed by Japanese cedar (Cryptomeria japonica) and western arborvitae (Thuja x plicata). These three evergreen species have a rapid growth rate and eventually attain heights of 40-60 feet, […]

‘Janet Blair’ Rhododendron

Here in the Southern Appalachian region (USDA zones 6 and 7) rhododendrons can be challenging. Of critical importance is to choose a good garden spot and to plant a hardy cultivar. Over the past 25 years ‘Janet Blair’ has been one of the most reliable varieties in my Northeast Tennessee garden.  ‘Janet Blair’ bears medium-sized […]

Growing Azaleas in Outdoor Containers Year-Around

In the Southern Appalachian region (USDA zones 6 and 7), if you desire to grow azaleas in above ground containers year around, you must select winter hardy cultivars. Two of the best for containers are ‘Elsie Lee’ (2½- inch wide semi-double light lavender blooms) and ‘Herbert’ (1 ¾- inch wide bright purple with dark blotch). […]

Stop Ignoring Enkianthus

From the photo, looks like a pieris? No, it’s redveined enkianthus (Enkianthus campanulatus) and its brightly colored bell-shaped flowers are attention getters in the early May garden. Lovely cream yellow to orangy red bell shaped flowers are faintly red veined. The bell shaped blooms exude a slight scent, one that you may like or not. From the start, growth rate […]

“Mary, Mary, How You Do Grow in My Garden”

‘My Mary’ is a hybrid deciduous azalea (R. ‘Nacoochee’ x R. austrinum) ending its flowering cycle in my spring garden. ‘My Mary’ has been a steady performer, averaging 4-5 feet in height in 10 years. Its clusters of bright yellow orange tubular flowers measure 2 1/2” across. Its early morning sweet fragrance is a gentle […]

Callaway Gardens

Perhaps, azaleas (Rhododendron spp.) offer the broadest color array of any shrub category in the spring garden. Very few public or private gardens display azaleas better than Callaway Gardens in Pine Mountain, GA. In late March, Jane and I enjoyed a 2-day visit at Callaway. We arrived to catch the early blooming azalea sequence and were not disappointed. […]

Take Flight With The Unique Dove Tree

Up for a challenge. Dove tree (Davidia involucrata) is a medium-size tree from China. Mature dove trees are 30-40 feet in height and 20-30 feet in width. A young tree exhibits a pyramidal form and forms a rounded canopy at maturity. The coarsely textured 4 – 5 inch circular leaves are bright green with no significant fall color, dropping either pale […]
