June 2012
The Merry Weather Garden Club met on Thursday, June 7th,
2012 at the home of Sallie Mabon.
Hosting with Mabon was Mary Anne Harman. Members and guests wandered
through admiring the Mabon’s Victorian home and ended in the garden beside her
koi pond and waterfall where the program was presented.
Lauren Johnson with
the Department of Natural Resources and a naturalist at FDR State Park
presented a program on Invasive Exotic Plants. Johnson first defined native
versus non native species with the emphasis on those species of plants not
native to our ecosystem and by introducing them in our area, we cause harm to
our health or the economy or environment.
We introduce plants
that are invasive for the same reason we plant other appealing plants: for
ornamental, landscape or agricultural purposes. As the garden club members were
all thinking kudzu and privet, Johnson reminded us that for every 100 plant
species introduced, only one becomes invasive.
Invasive plants
have several determining characteristics that make them invasive: they produce
lots of seed and effectively disperse them, they grow and mature rapidly, they
are long lived, adaptable to habitats, easily established, and have no natural
predators.
Invasive plants
damage the environment by competing native species, changing the plant
community, interfering with plant evolution, impacting wildlife and affecting
the recreational benefits of an area.
There are workshops
to learn more about the plants, and federal agencies created an invasive
species council. Georgia has an Exotic Pest Plant Council to help control such
plants as Chinese, Glossy, and Japanese Privets, Japanese Honeysuckle, Kudzu,
Nepalese Browntop, Golden Bamboo, Autumn Olive, Chinese Tallowtree, Hydrilla,
Mimosa, Wisterias, English Ivy, Queen Anne’s Lace, and Multiflora Rose. Of current
particular interest is Cogongrass that is invading the southern part of our
state. The DNR asks that we report any
sprigs of Cogongrass that we see.
Johnson explained
that certain species have a lag time.
While privet was introduced in the 1800’s, its growth habits did not explode
and become a nuisance until the 1950’s. Club members also discussed leaving English
ivy unmaintained in the landscape as well as the love of Queen Anne’s Lace and
managing wisteria.
After the program
the club members and guests were treated to a delicious brunch. The Next garden
club meeting will be in July at the home of Carla Snyder with co host Erma Jean
Brown and the program will be on landscaping the Southern home.
