Great Shrubs for Southern Landscapes
Volume 4, Issue 41 November 15, 2013 Great Shrubs for Southern Landscapes Ternstroemia gymnathera Ternstroemia gymnanthera, or Japanese Ternstroemia, is a dependable and adaptable broad-leaf evergreen shrub that is well-suited for southern landscapes. Formerly known as Cleyera japonica or Japanese Cleyera, Its ease of adaptability to either sun or shade and attractive color variations make this shrub a no-brainer for any landscape. Its similarity to the once popular shrub Photinia x fraseri stems from the plant’s colorful new growth. The young foliage ranges from bronze, red, reddish purple, to almost blackish purple as it emerges. The leaves are leathery to almost rubbery and mature to a dark, glossy green at maturity. In winter, the foliage may develop a reddish bronze color in winter. There are numerous cultivars of this species available, displaying a wide range of variation in color. Japanese Ternstroemia is a rounded, densely branched, upright shrub that typically reaches heights of around 8 to 10 ft. tall. It responds well to pruning, however, and can be maintained at any height. Although it does not grow exceedingly fast, it can reach greater height with age. A ten year old plant on our Director Jim Garner’s garden has reached a height of nearly 15 feet.

Oetter, Ph.D. Taylor Quedensley, Ph.D. Dede Reoch Joni Smith Bruce Vaughn, CFP Al Woods where Jim and our Director of Horticulture, Bradley Roberts, formerly worked, a mature specimen there has exceeded 20 feet in height. The foliage is by far more attractive than the flowers, which are small, white, and relatively inconspicuous. For best results in your garden, plant T. gymnanthera in a moist, well-drained, acidic soil. This is a very adaptable plant, and it will perform well in shady situations, although it is tolerant of full sun. This glossy easy-to-manage shrub can be used as an accent plant or mixed into the border. It can also do well as a screen or hedge, as long as the shrubs are planted 4 to 6 ft. apart. Lockerly has several Japanese Ternstroemia cultivars, which were donated by Flowerwood Nursery of Loxley, AL in 2008. These donated cultivars are planted in a shady shrub border along the northeastern front of the Arboretum property, and although they have grown slowly, that have performed exceptionally well. The Flowerwood cultivars we have include ‘Sotall,’ or Cleyera Bigfoot™. This cultivar grows faster than the species and produces large, glossy, light green foliage. It also grows much more vertically than the species, hence the cultivar name. ‘Conthery,’ or Cleyera Bronze Beauty™, is a lovely, upright selection with a billowing habit. The common name is derived from the foliage color, which is an attractive green-orange color. There is Foliage of ‘Bronze Beauty’ also ‘Contherann,’ or Cleyera LeAnn™, which features evergreen leaves that turn a beautiful maroon color in the fall. This selection makes a particularly excellent medium-sized hedge. Many other colorful cultivars are available, including ‘Burgundy’, ‘Burnished Gold’, ‘Copper Crown’, Jade Tiara, and Sovereign. Whichever Japanese Ternstroemia cultivar you choose for your landscape, rest assured that it will do well in our region. Few pests or diseases affect it, and deer are not attracted to it. Its drought tolerance, ease of maintainability and lovely coloring are all aspects that make this broadleaf evergreen shrub one of the best choices for southern landscapes. Garden Pathway Flower Border Extension Lockerly’s grounds crew has completed another phase of our ongoing Garden Pathway project. This current phase involved extending one of the flower borders installed last spring. The new section was begun by tilling a 90 foot long section bordering the walkway that is five feet wide. The next step was to add an eight in layer of topsoil to the tilled area. A trench was excavated down the center of the bed, and fully automated irrigation system was then Aster cordifolius ‘Avondale’ Coreopsis verticillata Baptisa ‘Purple Smoke’ Dianthus gratianopolitanus ‘Bath’s Pink’ Iberis sempervirens ‘Alexander’s White’ Achillea ‘Moonshine’ Phlox subulata Verbascum ‘Temptress Purple’ Gaura lindheimeri ‘Whirling Butterflies’ Heuchera villosa Verbena rigida ‘Touch of Style’ installed. Lastly, a layer of Natures Helper, an organic soil conditioner consisting of composted pine bark, was applied, and the entire bed was then amended with lime, gypsum, and a pre-emergent herbicide. Today we began planting this new flower border with herbaceous perennials and antique roses. The initial planting in this new section included the following: Veronica peduncularis ‘Georgia Blue’ Dianthus ‘Neon Star’ Phlox paniculata ‘David’s Lavender’ Phlox paniculata ‘Common Purple’ Coreopsis ‘Sienna Sunset’ Aster ericoides ‘Heath Aster’ Aster grandiflorus Aster oblongifolius ‘Jane Bath’ Gillenia trifoliata Salvia ‘Indigo Spires’ Achillea millefolium ‘Oertel’s Rose’ The roses we are planting include: Rosa ‘Le Vesuve’ Rosa ‘Madame Antoine Rebe’ Rosa ‘Natchitoches Noisette’ Rosa ‘Mutabilis’ Rosa ‘La France’ We were quite successful in raising funds for this project on through the Georgia Gives Day initiative this week. Altogether, we received $2,840.00 dollars in donations from individuals through this program conducted by the Georgia Center for Nonprofits. Additionally, our participation in this event qualified us for a $2,500.00 award from the Community foundation of Central Georgia. We thank everyone you has supported installation of our Garden Pathway project through their generous financial contributions that have made this important project possible. Rosa ‘Le Vesuve’
