Invasive Plants in the Landscape

Invasive plants are defined as those that are nonnative and cause harm to the economy, environment or human health. These plants are highly adaptable, quick growers, and difficult to eradicate.  Although there are many invasive plants to watch out for, below are several that are frequently seen in the landscape.

Privets (Japanese, Border, Chinese and Common), Ligustrum genus 

These invasive shrubs mainly spread through seed, often distributed by birds which have eaten the fruit. Once established the shrub will colonize the area, forming dense thickets which choke out any native species that would otherwise occupy the area.  What makes the Ligustrum species difficult to eradicate is its ability to regenerate new growth from roots and stumps. Privet pollen is also a severe allergenic.

Alternative Native Species: Yaupon (Ilex vomitoria), Wax Myrtle (Myrica cerifera), Inkberry (Ilex glabra)

Burning Bush, Euonymus alatus

Burning bush was introduced into the United States for use as an ornamental shrub. Its attractive, bright red fall color has made it a popular choice but its fast growing nature and exceptional seed production has landed it on the invasive list. This is another shrub that forms dense monotypic stands that reduces habitat diversity. In open woodlands this shrub will replace native shrubs while creating a dense root mass that prevents herbaceous growth.

Alternative Native Species: Red Cokeberry (Aronia arbutifolia), Winterberry (Ilex verticillata), Highbush Cranberry (Viburnum trilobum), Silky Dogwood (Cornus amomum)

Japanese Stilt Grass, Microstagium vimineum 

Introduced into the United States by accident, Japanese stilt grass grows in a variety of habitats from full sun to dense shade, preferring moist, acidic to neutral soils that are high in nitrogen. Spreading exclusively by seed, this annual grass can produce between 100-1000 seed per parent plant. Seeds often fall close but can be carried by water or moved around by humans or animals. Alternative native species will vary depending on site conditions

There are a number of strategies used to control these species including mechanical and chemical. The most important and easiest is to discover an invasion early and remove them before the population becomes too high. Preventing them from entering a vulnerable habitat in the first place is most ideal. Here at Cedar Run Landscapes we hope that by providing information about these plants and recommending the removal these species from the landscape can help minimize habitat destruction due to invasive plants.

Pond Plants Are In Stock

Is your pond up and running but, aesthetically, it’s missing something? Adding pond plants can provide additional interest in your landscape while helping to create a balanced ecosystem. Plant life filters water, removes excess nutrients, adds oxygen, and creates shade. These benefits along with the aesthetic qualities of pond plants provide a vital role in the development of a healthy pond system.

The four main types of plant life you can add to your pond system are oxygenating, floating, deep water, and marginal water plants. Each type has a specific function as well as grows in a specific area of the pond. Oxygenating plants are submerged in a pond and help introduce oxygen into the water. These types of plants also clean the water by feeding on decaying organic matter. Floating plants help cover the water surface, providing much needed shade to the water below.  Deep water plants, most commonly lilies, give the impression of a floating plant but are rooted deep below the pond surface. These types of plants also provide shade. Shading the water prevents ponds from over heating while also inhibiting algae growth. Marginal Water plants provide great water filtration and create interest along the edges of the pond.

Please stop by Cedar Run Landscapes if you would like to check out our selection of pond plants. We’ve had several requests to provide information about our pond plant selection online. Below are links to our pond plant inventory. We are a certified retailer of Van Bloem Gardens and have added a link to their online library, where you can search for pond plants by common or scientific name. While your visiting you will also find a thumbnail image of the plant species with basic information about that plant.
