Featured Ornamental Plant – ELAEAGNUS PUNGENS (Thorny Olive, Silverthorn)
  Featured Ornamental Plant: Elaeagnus pungens (Thorny Olive, Silverthorn)

      Some exotic ornamental plants behave badly when they escape from the place they
      are planted. Infestations of these plants have negative impacts on nature. One of
      these plants is Elaeagnus pungens; common name: Thorny Olive or Silverthorn.

                                       Elaeagnus pungens is a dense evergreen shrub in the family
                                       Elaeagnaceae (not a true olive). The native range of Elaeagnus
                                       pungens is Eastern Asia. It was introduced in the U.S. as an
                                       ornamental plant in 1830. It has been frequently planted in
                                       hedgerows and on highway right-of-ways and is also used for
                                       landscaping. It has escaped ornamental plantings and begun to
                                       spread into natural areas in the midlands and coastal plains of
                                       South Carolina. An example of a severe infestation can be seen
                                       at The Audubon Society Wannamaker Preserve on the north side
                                       of Hwy.6, five miles east of Saint Matthews, S.C. A project to
  control this infestation is ongoing by members of the Columbia Audubon Society in order to improve
  habitats for native birds and restore the native plant community.

  Elaeagnus pungens shrubs typically have multiple stems and very dense
  branches with long shoots extending from the top. Twigs are brown with
  brown scales and hairy when young. The leaves are alternate, oval to
  elliptical, with irregular wavy margins and silvery surfaces especially
  underneath, 2-4 inches in length and thick. Axillary clusters of small,
  sweet-smelling, white to brown flowers develop in the fall. Fruit are
  small, red, dotted with small brown scales and develop in the spring.
  Thorny Olive resembles two other exotic olives, autumn olive and
  Russian olive which also have silvery foliage. It also can take the form of a climbing plant, growing
  over and shading out other plants. The name Silverthorn, comes from the thorns on its branches.

                                    Elaeagnus pungens often becomes a problem when it escapes from
                                    planted landscapes into natural areas. Because Thorny Olive is a
                                    fast-growing, weedy ornamental, it can grow and thrive in a variety
                                    of conditions, and can tolerant shade, drought, and salt. Mammals
                                    and birds disperse seed, widening its area of distribution.
                                    Reproduction also occurs via stem sprouts. Silverthorn can spread
                                    and climb into trees, leading to the displacement of native
                                    vegetation. When established, an infestation reduces biodiversity,
                                    wildlife habitat quality, available forage, and native insect life.

  It may not be widely known among horticulturalists and
  landscapers that this plant can be harmful to natural habitats.
  Please consider removing this species from your inventory and
  gardens. There are several native shrubs that can be sold and
  planted in its place. These include the evergreens Morella
  cerifera (wax myrtle), Ilex vomitoria (yaupon holly), Ilex glabra
  (inkberry), Ilex opaca (American holly), Baccharis halimifolia
  (groundseltree), Osmanthus americanus (wild olive or
  devilwood), Kalmia latifolia (mountain laurel), or Leucothoe           Escaped plant
  fontanesiana (highland doghobble).

         Chinese Fringetree
        (Chionanthus retusus)
     One of the most enjoyable and reward-
     ing aspects of urban forestry is making the
     annual rounds to visit wholesale tree nurser-
     ies to select and tag trees for planting. Those
     foresters who order a specific list of trees by
     phone or through a broker are missing an
     opportunity to discover hidden treasures in
     the form of tree species or cultivars that are
     new or overlooked. One small species that is
     well worth the search is Chinese Fringetree,
     Chionanthus retusus. Originally introduced
     from Asia in 1845, the USDA Hardiness
     Zone for this tree ranges from 5 to 9B/10A
     (Gilman).

     While the native Fringetree, Chionanthus
     virginicus, may be better known, Chinese
     Fringetree has consistently provided supe-
     rior performance in Savannah, Georgia. The
     southern type of Chinese Fringetree can be
     grown as a standard in tree form, with a
     mature height and width range of 15 to 25
     feet. This superb tree has many desirable
     attributes. In the spring it is an absolute
     showstopper, displaying an explosion of cas-
     cading lacy white blooms on new terminal
     shoots as foliage emerges, whereas the native
     Fringetree flowers on older wood, prior to
     leaf emergence. During the growing season,
     rounded leaves are thick and leathery, with a
     lustrous dark green color which persists late
     into the year, slowly changing to yellow in
     December, occasionally even into January.

     Chinese Fringetree has proven to be more tol-                                   Licensed Grower of Encore Azalea®
     erant of a wider range of site conditions than
     traditional ornamentals. It grows well in full
     sun to partial shade, can handle occasional
     drought or wet feet, has few pest problems,
     and can thrive in the heat. One potential
     criticism from a management standpoint is
     that once established, annual terminal shoot
     growth in an optimal location can approach
     two feet or more. This can lead to an imbal-
     anced crown if uncorrected. Periodic pruning
     is necessary to maintain shape and form of
     specimen trees; however, the effort is well
     worth the reward.

     Individual seedling grown Chinese
     Fringetrees have a unique character which
     makes them a fine choice for use as a speci-
     men ornamental. Chionanthus retusus ‘Tokyo
     Tower’ is a new introduction from Japan with
     a narrow, upright growth habit (15-20’ height
     x 5-7’ width) that offers a great option for
     those smaller planting spaces that don’t quite
     accommodate a larger tree.
