7 Spreading Plants To Fill In Open Areas

There are a number of attractive plants that have a reputation for spreading out across, and sometimes beyond, the area in which they are planted. This can be a problem and it is advisable to investigate the “spreading habit” of any plant before you buy, if that is a potential problem in the designated planting location.

But a plant’s “spread-ability” is not necessarily a bad thing. Spreading plants can be just what you are looking for in the right circumstances. They can choke out weeds, reduce soil erosion and beautify a sloping or rocky area that is difficult to mow.

Here are seven spreading plants favorites that you should take a look at if you have an area that could benefit from some low-growers that tend to spread.

Laurentia Blue Star Creeper

In my opinion, this is one of the most versatile ground covers you can find. Throughout the growing season, you’ll see a virtual carpet of bright green foliage that continues right into winter. In June/July, it produces a mass of tiny purplish-blue flowers with white markings. A tough, long-lasting plant, Blue Star Creeper is easy to grow. Each plant reaches a height of no more than a few inches, spreading out to six inches or so, making it ideal for rock gardens and in between stepping-stones.

Trailing Verbena

Trailing verbenas often withstand heat and mildew, and that can be an important benefit in some areas. It produces large burgundy blooms on dark green leaves and will regenerate vigorous growth when you cut it back. With a maximum height of twelve inches, it makes a colorful groundcover that is popular with Swallowtail butterflies, and is a good choice for containers, baskets and window boxes.

Creeping Red Thyme

You might be aware of the fragrance before you even see this fast, low-growing evergreen that is a good choice as a ground cover or between pavers for an attractive, rustic look. Thyme is easy to grow in full or partial sun.

Creeping Phlox (Phlox subulata)

A rocky embankment or outcropping where weeding, tending or mowing is hazardous or impossible? Creeping Phlox could be an ideal solution. I’ve also admired it in the nooks and crannies of dry stone retaining walls and around rock waterfalls. Locations of that nature are ideal for Phlox as it enjoys the good drainage provided by elevated planting. For contrast, try mixing Emerald Blue or Red with Creeping Candy Stripe Phlox with its tiny pink and white flowers.

Liriope Big Blue

For some thing a bit taller, try this tufted evergreen ground cover with its arching, grass-like foliage. In the summer, you’ll see an abundance of blue flower spikes that are followed by clusters of black berries in the fall. In addition to hard-to-get-at areas, Liriope is a good choice for borders and edging.

Trailing Periwinkle or Vinca minor

Continuing the “blue” theme, don’t forget Trailing Periwinkle, a delightful evergreen with dense, shiny, oval-shaped foliage that forms an almost flat, springy carpet adding soft, rolling contours to landscaping. In early spring, the foliage is covered with blue (yes, periwinkle blue) flowers. Vinca minor likes fairly good soil and does well in full sun, partial sun or shade.

Pachysandra terminalis

Introduced from Japan circa 1882, pachysandra is one of the most planted ground covers in America. Most everyone is familiar with this rapidly spreading plant that thrives even in the dense shade of evergreens.

A spreading plant isn’t necessarily a negative, as long as you plant it in a location where its natural tendency is a benefit rather than a nuisance.
