In container garden design they always use terms such as “thrillers, spillers, and fillers” in regard to plant attributes and function.
“Thrillers,” are large and colorful plants in the middle of the container, while “fillers” have rounded and interesting forms occupying the mid-area.
“Spillers” — one of which we will talk about today — are plants that gracefully cascade over the edge tying the whole design together.
The “spiller” I want to highlight here is called Muehlenbeckia axillaris Nana, also known as the creeping wire vine. Available at most garden centers, this plant is made for large containers, hanging baskets and/or rock gardens.
Featured in the large planting containers — designed and installed by UF/IFAS Charlotte County Master Gardener Volunteers — just outside the Murdock Administration Building in Port Charlotte, creeping wire vine is a natural “spiller” growing no more than 3 to 4 inches tall, and up to 3 feet wide. ‘
Nana is a dwarf cultivar of the species with small green leaves that are alternatively arranged on brownish-red wiry stems.
You might also notice very small almost inconspicuous flowers at times, but they do not overly enhance the ornamental appeal of this plant.
Best in full sun to part-shade, creeping wire vine is normally grown in large containers and hanging baskets.
As mentioned above, because of its trailing habit, it is a natural feature where it can freely surge over the rigid boundaries of pot rims — in effect, “spilling out.”
The extra-small leaves of Muehlenbeckia axillaris Nana nicely complement other features in the container garden knitting everything together into an eye-appealing horticultural treat.
Creeping wire vines can also be grown by themselves in hanging baskets which they will quickly fill and spill over creating a stunning display.
Not reported to be invasive in Florida, keep creeping wire vines in bounds to prevent escape — just in case — if you use it in the landscape.
Functional as a low groundcover in rock gardens, creeping wire vine really fits the bill as its fine leafy texture and predilection to sprawl fit well into small open bare areas.
The literature also indicated that creeping wire vine can tolerate foot traffic to a degree which is unusual for most groundcovers.
You will find it fairly fast-growing, somewhat salt-tolerant and drought-tolerant once established
Creeping wire vine is readily available at most local nurseries and garden centers. This small evergreen can be propagated by cuttings and division if additional specimens are required.
Consider adding Muehlenbeckia axillaris Nana to your plant palette this year. You will be rewarded with a “spiller” of a plant!
