National Invasive Species Awareness Week

Filed under: chinese, Honeysuckle, invasive, Japanese, ligustrum, Lonicera, plants, privet, species, wisteria — shadygardens @ 3:36 pm
National Invasive Species Awareness Week is February 23-28, 2014. Invasive species involves more than just plants, but as you know, plants are my thing. Seeing invasive plants being sold in big box stores to uninformed gardeners is my pet peeve. 

I’ve written about these before, but I despise these invasive plants that are still commonly sold and planted right here in Georgia:

Chinese and Japanese Wisteria should never be planted here

Chinese Privet is dispersed when birds eat the berries




Privet in the garden center might also carry the name Ligustrum, so beware.

For what to plant instead of these invasives, please read Alternatives to Invasive Plants in the Garden.

Plants for Pollination: Helping the Bees Year Round

Filed under: bees, gardens, Georgia, Honeysuckle, jasmine, list, plants, pollination, privet, university — shadygardens @ 3:22 pm
Interested in providing plants for bees year round? I just found a list and thought I’d share it with you. Although the list claims to be “incomplete,” it certainly is a great starting point. Perhaps you will find that you have a great number of these plants already in your garden or growing nearby. This list is for Georgia gardeners, but if you live in another state, you might find a similar list on your state’s university website. I found my list on the website for the University of Georgia College of Agricultural & Environmental Sciences.
Unfortunately, some of the plants on this list are very invasive and I would never recommend you plant them. Privet should not be planted in Georgia, but I bet you either have it in your yard or as in my case, on a nearby neighbors property. Privet has escaped into the wild all over the Southeast. Although my neighbor probably did not plant this invasive shrub, it is everywhere.

Also, bloom times on this list might not be the same for you. According to the list Lonicera fragrantissima (Winter Honeysuckle) blooms in April, but it blooms here in January or February, depending on the winter we get.  Gelsemium sempervirens (Carolina Honeysuckle) is listed for March and April, but this native vine also blooms in Winter here, and has usually finished blooming by March in our area.  These differences are probably because UGA is in North Georgia.

Invasive Plant Alternatives #1: Evergreen Shrubs

Filed under: alternatives, Berries, boxwood, holly, invasive, Itea, ligustrum, native, plants, privet, Sweetspire, viburnum, yew — shadygardens @ 2:30 pm
Many popular landscape plants seem harmless, but they are actually invasive plants which move quickly into the surrounding areas to crowd out native plant species. Once established, these plants are capable of strangling trees and covering up native plant species on which many of our beneficial insects and wild animals depend for their survival. This change to our environment could drastically alter our eco-system.

Most of these popular invasive species have a native counterpart that is much more desirable in both appearance and behavior.

Privet, or Ligustrum, is a highly invasive species found growing all over the South. Once it moves into an area, privet is very difficult to eradicate. It seems this problem will never go away, since to my surprise it is still sold in big box garden centers and planted in enormous proportions by landscapers and home owners everywhere. It can be found in almost every landscape. Once one person plants it, it will eventually be all over the neighborhood, since birds eat the small dark berries (see photo shown below) and drop seeds anywhere they deposit their droppings.
Privet Berries are eaten by birds, therefore privet seeds
are deposited in bird droppings all over the neighborhood.
In my opinion, privet is not even pretty, and I don’t know why people plant it, unless it’s because it’s evergreen. Our property is surrounded by thickets full of privet which, since it is not our land, we can do nothing to eliminate. And believe me, when it blooms, it really wreaks havoc on my sinuses and I keep a migraine until the blooms fade, because I cannot escape the strong fragrance permeating our entire garden.

There are certainly many superior alternatives to this pest. I could go on and on with a list, but any fine, textured evergreen would be better than privet. Here are just a few suggestions, all evergreen, some of which also have beautiful flowers or bright berries for the birds to eat:

  • Boxwood is much slower-growing, making it far superior to privet, since privet must be pruned every few weeks to keep it tidy. Boxwood is also available in dwarf sizes and variegated forms, making it absolutely unnecessary to ever plant any variety of privet.
  • Hollies are excellent in any garden. Dark green glossy leaves in a variety of textures with beautiful berries in shades of yellow, orange, or red provide plenty of interest. Dwarf yaupon holly is a native holly with small leaves giving a fine-textured appearance similar to privet, but without the maintenance.  When choosing holly for the garden, the possibilities are endless. 
  • Yew is a lovely evergreen plant that is available in a variety of forms: upright, conical, or spreading. (Also, deer will not eat it–Yay!)
  • Viburnum is available in small-leaved evergreen varieties such as Davidii, Compactum, or Sandankwa as well as some deciduous species with bright fall foliage color. Many varieties have hydrangea-type bloom clusters and some put on a bright display of beautiful berries in the Fall. 
  • Itea, Virginia Sweetspire, is a lovely shrub available in large or dwarf-growing sizes. Sweetspire has fragrant bottlebrush blooms in spring and one of the showest fall color displays of any shrub, native or not!

I hope you will consider some of these suggestions, and plant shrubs that are not invasive instead of invasive exotics. Thus you will be helping to preserve our environment as it is, for our wildlife neighbors and for our children.

Privet Is An Invasive Plant! Don’t Plant It In Your Garden!

Filed under: alernative, invasive, plant, privet, rose, viburnum — shadygardens @ 2:44 pm

Many invasive plants are still commonly sold and planted here in the Southeast. One still popular but very invasive plant that should not be planted in your garden is the Chinese Privet. Once planted, this invasive shrub is difficult to eradicate. Privet produces tiny berries by the hundreds that are eaten by birds and planted all over the neighborhood. Very soon privet begins popping up in nearby woods and meadows, developing tight thickets that crowd out native plants. I find it ridiculous that privet is still so widely sold and recommended for hedge plantings.

Privet is often chosen at garden centers when the homeowner is looking for a privacy hedge or evergreen shrub that is easy to grow. There are many better choices out there, since just about any plant is better than privet. For alternatives to privet, try visiting your local native plant nursery or a locally owned nursery. There you will find a knowledgeable nurseryman that would have suitable alternatives to privet.

Some plants to consider instead of privet:

  • Viburnum – some species are evergreen, most produce large flowers in spring and showy berries in fall, as shown in the above photo. There are both native and non-native varieties.
  • Roses provide showy blooms and easy care, if you choose a carefree shrub rose. In addition to beauty, the thorns on most shrub roses can provide a barrier for intruders if that’s your goal.
  • Holly. Whether you choose an American native variety or not, holly provides berries and beautiful foliage. Some species are evergreen and even variegated. Holly is a favorite of birds as a food source and nesting site.

When planning a hedge, I always suggest a mixed shrub border rather than a long row of the same plant. A mixed shrub border can provide beauty and interest 12 months a year, and with variety, you can provide food and shelter for birds and other desirable wildlife. Plants with berries should be included as a food source, and birds love to build nests in thick bushy shrubs with spines or prickly leaves. When you have a variety of plantings in your garden, you are contributing toward diversity that is important for preservation of the environment.

Alternatives to Invasive Plants in the Garden

My gardening goals have changed much over the years. In the beginning I was enticed with plant descriptions such as ‘fast growing’, ‘prolific spreader’, or ‘reseeds freely’, envisioning a lush garden covered with beautiful plants after minimal monetary investment and less work.

Perhaps it was when I enrolled in the Master Gardener Class that I learned of the dangers of planting invasive plants, but it should have been obvious to me sooner. I need only to step outdoors to view the rampant spread of the very aggressive Japanese Honeysuckle. Every time I drive my children to school, I see hillsides overtaken with Kudzu.

Now I view planting invasive exotic plants as down right wrong. Aggressive plants like Kudzu can completely take over a whole field in little time, even killing large trees by blocking sunlight and stealing the very little water we get during drought common to this part of the country.

So as you plan additions to your garden this year, take a moment to investigate a plant’s reputation before adding it to your garden.

To offer a little assistance, here’s a short list of invasive plants that are still bought, sold, and planted, along with a more environmentally-friendly alternative:

  • Japanese Honeysuckle – Plant our native honeysuckle instead, Lonicera sempervirens, commonly referred to as Red Trumpet Honeysuckle or Coral Honeysuckle.
  • Japanese Pachysandranda – Instead, try our native Pachysandra Procumbens, which is variegated, offering much more beauty than the plain green invasive one.
  • Privet – Well, there are many alternatives to Privet. Anything at all would be better. For a non-invasive hedge, consider holly, viburnum, shrub roses, or camellias.
  • Wisteria – Yes, we even have a native wisteria that’s much better than the very invasive Chinese or Japanese Wisteria. Wisteria frutescens ‘Amethyst Falls’ is available in many nurseries and home improvement stores. Before buying wisteria, check the label. If it merely reads ‘Wisteria,’ stay away from it. If it’s Wisteria frutescens, it’ll be labeled as such.

Native Plant Alternatives to Invasive Species Like Honeysuckle, Privet, Tallow, and Wisteria

Many popular landscape plants seem harmless but are actually invasive plants that are moving into the surrounding areas and crowding out native plant species. Once established, these plants are capable of strangling trees and covering up native plant species on which many of our beneficial insects and wild animals depend for their survival. This change to our environment could drastically alter our eco-system.
Most of these popular invasive species have a native counterpart that is much more desirable in both appearance and behavior!
Listed below are some commonly planted invasive plant species with some alternatives.
Chinese Tallow Tree (Popcorn Tree) is prized for its fall color, but is one of the worst invaders into our forests because of the rapidly dispersed seed. It is a lovely tree, but consider these alternatives:
Sassafras – a native small tree with beautiful fall color and large unusually-shaped leaves. It is easy to grow and tolerant of a variety of growing conditions.
Serviceberry – another native tree noted for its spring flowers and fall color with the addition of beautiful berries which are food for the birds.
Fothergilla – yet another native American tree/small shrub with showy, sweet-scented, white bottlebrush flowers in spring, and excellent fall foliage in shades of orange, red, and burgundy.
Viburnum – there are many varieties, both native and non-native, that are lovely, consisting of beautiful, showy blooms and many also have berries in shades of white, blue, pink, and red that provide wildlife food, and some ending up with beautiful fall foliage, while others are evergreen—yet they are never invasive!
Sourwood cannot be beat in my opinion. It’s my favorite native tree, because in addition to beautiful maroon foliage in early fall, Sourwood has fragrant blooms in early summer that look and smell like Lily of the Valley!
Chinese Privet is a highly invasive species that is all over the South! The plant is rapidly spread by birds who eat the small dark berries. Privet is very difficult to eradicate, since it’s still sold and planted in enormous proportions. It can be found in almost every landscape. In my opinion, it isn’t even very pretty, and I don’t know why people plant it, unless it’s because it’s evergreen. There are certainly many superior alternatives to this pest. I could go on an on with a list, but any fine, textured evergreen would be better. Here are just a few suggestions:
Boxwood is much slower-growing, which is an asset, since Privet must be pruned every few weeks to keep it tidy. Boxwood is available in dwarf sizes and variegated forms, making it unnecessary to ever plant privet.
Hollies are excellent with dark green glossy leaves and beautiful berries in shades of yellow, orange, and red. Dwarf yaupon holly is a native holly with small leaves giving a fine-textured appearance.
Yew is a lovely evergreen plant that is available in a variety of forms.
Viburnums are available in small-leaved varieties such as Davidii, Compactum, or Sandankwa.
Itea, Virginia Sweetspire, is a lovely shrub available in large or dwarf-growing sizes. Sweetspire has fragrant bottlebrush blooms in spring and one of the showest fall color displays of any shrub, native or not!
Japanese Honeysuckle appeals to many gardeners due to its fast-growing habit and its sweetly scented blooms, but the fact that it’s fast-growing is what has caused it to take over the South! Japanese Honeysuckle is one of the most common nuisance plants, yet it is still sold in garden centers everywhere!
American Native Honeysuckle, shown in the photo above, is one of the best hummingbird magnets I know of, with its large red tubular flowers that come year round in my garden. (There were a few blooms on mine even in January here in West Central Georgia!)

Confederate Jasmine (Star Jasmine) is an evergreen vine with sweetly-scented white star-shaped flowers.
Lady Banks Rose comes in 2 colors—white blooming which is very fragrant, and yellow blooming which is not. Both varieties thrive with neglect, and the largest, oldest rose bush in the country is a white Lady Banks Rose growing in Tombstone, Arizona! That should give you an idea of how easy it is to grow. That bush is over 100 years old!
American wisteria, yes, I did say wisteria!!, is a native vine that is just as beautiful as the Chinese and Japanese wisteria, but is not invasive at all. The blooms are very fragrant. You might see it sold as Amethyst Falls wisteria, but don’t be afraid to plant it. Avoid Chinese and Japanese wisteria, because I can show you how it’s taking over much forestland in Alabama and Georgia, strangling and pulling down trees, much like kudzu.
Clematis is available in many varieties, both native and non-native species.
Passionvine is another native perennial vine with very showy, large purple flowers and attractive, edible fruits. This vine will self-sow, but never crowds out its neighbors.
I hope you will consider some of these suggestions, and plant native plants instead of invasive exotics. Thus you will be helping to preserve our environment as it is, for our wildlife neighbors and for our children.
