Non Invasive Plants for a Sustainable Garden

Having a sustainable garden is not only good for the environment, but it's also a great way to create a beautiful and thriving outdoor space. By choosing non-invasive plants, you can avoid harming local ecosystems and prevent the spread of invasive species.

Some non-invasive plants are native to your region, which means they're naturally adapted to the local climate and soil conditions. For example, the American beautyberry (Callicarpa americana) is a native plant to the southeastern United States and is known for its vibrant purple berries.

Native plants like the American beautyberry require less maintenance and care, as they're already accustomed to the local conditions. This can save you time and money in the long run, and also reduce your carbon footprint.

By incorporating non-invasive plants into your garden, you can create a harmonious and balanced ecosystem that benefits both you and the environment.

If you're looking to replace invasive plants in your garden, there are many alternatives you can choose from. A new guidance booklet from Coventry University lists over 160 non-invasive plants that can be used in their place.

One option is to use native plants that are similar to the invasive species you're trying to replace. For example, if you want to attract wildlife to your garden, you can plant species like Yarrow (Achillea millefolium), Night-scented stock (Matthiola longipetala subsp. Bicornis), or Purple angelica (Angelica gigas).

If you're looking for tree alternatives, there are many native options available. Here are a few examples:

Shrubs are another area where you can find non-invasive alternatives. For example, if you're looking for a shrub that attracts pollinators, you might consider using a species like Aesculus parviflora (Bottlebrush Buckeye) or Calycanthus floridus (Sweetshrub).

Groundcover alternatives are also available, and can be a great way to add some color and texture to your garden. Some options include Chrysogonum virginianum (Green and Gold) or Phlox divaricata (Woodland Phlox).

Ornamental grasses are another area where you can find non-invasive alternatives. For example, if you're looking for a grass that adds movement and texture to your garden, you might consider using a species like Eragrostis spectabilis (Purple Love Grass) or Muhlenbergia capillaris (Muhly Grass).

Ground Covers and Groundcovers are actually the same thing, but it's worth clarifying the difference between invasive and non-invasive groundcovers.

Invasive non-native groundcovers can be a real problem, and some examples include the Autumn Fern (Dryopteris erythrosora), English Ivy (Hedera helix), Bigleaf Periwinkle (Vinca major), and Common Periwinkle (Vinca minor).

These plants can outcompete native species and cause damage to ecosystems. It's essential to avoid using them in your garden.

Some native groundcovers are great alternatives, such as Green and Gold (Chrysogonum virginianum), False Rosemary (Conradina canescens), and Allegheny Spurge (Pachysandra procumbens).

Here are some examples of non-invasive groundcovers that you can use in your garden:

You can also consider using plants like Silver Carpet (Corethrogyne filaginifolia 'Silver Carpet'), which is a non-invasive groundcover that's perfect for creating a beautiful, low-maintenance garden.

Native plants are a great choice for your garden, as they're often more resilient and require less maintenance than non-native plants. You can find native plant resources in your area by checking out the Georgia Native Plant Initiative (GNPI) List or the GNPS Native Plant Sources List.

Some examples of native plants include the Purple Love Grass (Eragrostis spectabilis), which is a great alternative to the invasive Purple Love Grass, and the Sweetshrub (Calycanthus floridus), which is a shrub that's native to the southeastern United States.

Native plants can also be used as ornamental plants, and some great alternatives include the Bottlebrush Buckeye (Aesculus parviflora), the Fetterbush (Agarista populifolia), and the Dwarf Fothergilla (Fothergilla gardenii).

If you're looking for native plants in Georgia, there are several resources to check out, including the GNPS Native Plant Sources List and the Georgia Native Plant Initiative (GNPI) List. These lists can help you find plants that are native to your area.

Roundstone Native Seeds and Prairie Moon Native Nursery are two online native plant sources you can consider. Before purchasing seed mixes, make sure to check the species to ensure they are all native to your area, and remove any unwanted species from the mix.

The UGA Extension Guide to Native Plants for Georgia is a large PDF file that provides valuable information on native plants for the state. GA DNR Wildflower Meadow Planting Basics is another resource that can help you learn more about native plant gardening in Georgia.

The Georgia Green Industry Association encourages the use of non-invasive species, and the GISC list can help you identify plants that are less likely to be invasive. To ensure you're using the right plants, refer to the GISC list or contact your county extension agent at 1-800-ASKUGA1.

Shrubs are a fantastic option for adding some greenery to your garden, and they come in a wide variety of shapes, sizes, and colors.

If you're looking for a low-maintenance option, consider the Oregon grape (Berberis aquifolium), which is a great choice for hedges or borders.

The island bush poppy (Dendromecon harfordii) is another great option, with its delicate white flowers and gray-green leaves.

If you're looking for something a bit more showy, the flannel bush (Fremontodendron californicum and cultivars) is a great choice, with its bright yellow flowers and fuzzy leaves.

Some popular shrubs for hedges and borders include the griselinia (Griselinia littoralis), the coffeeberry (Frangula californica and cultivars), and the sweet bay (Laurus nobilis and cultivars).

Here are some popular shrubs to consider:

Small gardens can be a challenge to plan, but there are many non-invasive plants that can thrive in these spaces. These plants are perfect for small gardens because they won't take over the entire area.

One option is the rose bush, which is very easy to maintain and can be used as a border around gardens. It only grows to be roughly 2-3 feet tall and 2-3 feet wide, making it perfect for small gardens.

To ensure the best blooms, these plants need at least 6-8 hours of sun. Dogwood trees are another option, and they come in a dwarf form that will grow 8-10 feet tall and wide, making them suitable for small gardens.

Shallots are a great vegetable to include in gardens because they are non-invasive and easy to control in terms of yield. They're also easy to preserve throughout the winter season.

Clematis vining plants are perfect for small gardens with a trellis, and they add a hint of color with their striped flowers. Swiss Chard is another option, creating leaves for many months throughout the year.

To ensure you're using non-invasive plants, check the Georgia Green Industry Association's list of invasive plants and only grow, sell, and plant non-invasive species.

The Georgia Native Plant Initiative (GNPI) List and the GNPS Native Plant Sources List are great resources to find native plants that are suitable for your area.

You can also check online native plant sources like Roundstone Native Seeds and Prairie Moon Native Nursery, but be sure to check the species in seed mixes before purchasing to ensure they're all native to your area.
