Great Trees for Georgia Landscapes
Volume 4, Issue 17 May 22, 2013 Great Trees for Georgia Landscapes The genus Stewartia is made up of a group of small trees that are native to Korea, Japan, and the southeastern U.S. The trees of Stewartia are slow-growers that feature lovely white flowers in spring. This genus of trees is also known for its attractive bark, which exfoliates to reveal colors underneath in the fall and winter. Table of Contents Great Trees for Georgia Landscapes pg. 1 Garden Pathway Progress pg. 2 Stewartia monadelpha, or Tall Stewartia, is one of the easiest in the genus to grow, and it is the most heattolerant species, making it an good choice for your Southern landscape. This tree features a shrubby and multi-stemmed habit with dark green leaves that develop into a beautiful Lockerly Trustees dark red fall color. The leaves hold late into the autumn months. In spring, small white flowers open that are similar David Evans, in appearance to Camellias. The tree itself grows to heights President of around 20 to 30 ft. tall. Lockerly actually has the state champion of this species located in the arboretum, meaning Joe Mangum, it is the largest specimen known in the state. Vice President Stewartia pseudocamellia is commonly known as Japanese Stewartia. The five-petaled white flowers of this Stewartia monadelpha Sherrill Jones, tree, with their golden-orange centers, Secretary/Treasurer are extremely similar to those of Camellia. The bark of S. pseudocamelKathy Chandler lia exfoliates to reveal colors of gray, Rodger Flotta orange, and red-brown, making it a Jan Flynn, Ph.D. true sight for sore eyes in the middle of a bland winter. The leaves emerge Doug R. Oetter, Ph.D. a bronze-purple color, developing into Taylor Quedensley, a dark green before turning excellent Ph.D. shades of orange and red in the fall. Dede Reoch For best results, plant your Japanese Joni Smith Stewartia in full sun in moist, welldrained soil. In the arboretum, we have Bruce Vaughn, CFP Al Woods a small specimen that is growing in Stewartia pseudocamellia blooms shade, but hasn’t flourished in that lowlight environment. Stewartia rostrata, or Upright Stewartia, is a rare selection that features single, attractive white flowers and dark green foliage. The habit of this tree is small and upright, making it an easy addition to almost any landscape. At its maximum height, it can reach about 30 ft. tall. Unlike other Stewartias, plant this selection in the shade with additional moisture, as our Southern summers can really inhibit the growth of this lovely plant. We have one in the arboretum that is doing quite well. Stewartia serrata Stewartia serrata is commonly known as Sawtooth Stewartia, as its leathery leaves are serrated at the edges. This small tree has a stained red base and, like other Stewartias, cup-shaped, attractive white flowers. These flowers are small and fragrant with yellow stamens in their center. Interestingly, this is one of the first Stewartias to flower in spring, with its blooms appearing in early June and lasting through the summer months. Its bark is a cinnamon-brown color and exfoliates. This tree also sports fantastic fall color, as its leaves develop into a purple-red color come October. At maturity, Sawtooth Stewartia can reach heights of around 25 ft. tall with an equal spread. We do not have this species in the arboretum, but Jim Garner has one in his landscape in Eatonton, where it has done quite well. Garden Pathway Progress Last week we began construction on the next portion of Lockerly’s new Garden Pathway feature. A second flower border is being added to the southern end of the walkway. Construction began with grading work, grassing, and addition of topsoil. The next phase involved installing a French drain and automatic irrigation system. The pathway’s new plantings will consist of a variety of annuals and perennials, centered around fifteen Rosa ‘Caldwell Pink,’ which is one of the most durable and floriferous roses available today. It is a repeat-flowing rose featuring lilac-pink flower clusters that does well in most soil conditions. This rose of unknown origin was discovered growing at an old home site in Caldwell, Texas. All of the ‘Caldwell Pink’ roses used in this planting were grown from cuttings propagated in Lockerly’s greenhouses. The Garden Pathway will serve as an enduring feature at Lockerly for years to come. We are seeking continued financial support from our community to complete this important garden feature. Please consider making a tax-deducible donation in any amount to help us with the cost of materials and labor to complete this project.
