Privet honeysuckle (Lonicera pileata 'Royal Carpet')
Lonicera pileata 'Royal Carpet' is a low-maintenance, broadleaf evergreen ground cover offering glossy green foliage and fragrant blooms.
Complete Plant Information
Overview
Lonicera pileata ‘Royal Carpet’, commonly known as Privet honeysuckle, provides excellent, dense coverage ideal for softening large landscapes or stabilizing slopes. This broadleaf evergreen offers shiny green foliage that remains attractive throughout the year, especially in warmer climates where it sustains its semi-evergreen status. Gardeners appreciate the low maintenance requirements of this spreading shrub.
The primary appeal of Lonicera pileata ‘Royal Carpet’ lies in its vigorous, horizontal growth habit, forming appealing mats up to eight feet wide while staying only one to two feet tall. Its small, fragrant yellowish-white flowers appear intermittently from May through November, adding subtle seasonal interest. For gardeners seeking reliable, tough coverage, this variety excels where many turf grasses struggle.
Whether used as a formal ground cover or allowed to naturalize beneath taller trees, the Privet honeysuckle establishes quickly. Its ability to root where branches touch the ground aids in creating a thick, weed-suppressing carpet, making Lonicera pileata ‘Royal Carpet’ a highly practical choice for banks and wide borders.

How to Grow
Plant Privet honeysuckle during the cooler months, spring or fall, ensuring the soil is humusy, organically rich, and well-drained. While Lonicera pileata ‘Royal Carpet’ tolerates full sun, providing afternoon shade is advantageous in regions experiencing hot summers, which helps prevent foliage burn. Proper drainage is crucial for the long-term health of this woody ground cover.
Watering needs are medium overall, but vigilance is required based on sun exposure. Plants situated in shadier locations demonstrate good drought tolerance once established. Conversely, specimens planted in full sun require regular moisture to maintain dense, healthy foliage. Fertilizing is usually unnecessary if the soil is well-amended.
Pruning for this resilient shrub is minimal; handle necessary shaping or size reduction immediately following the main bloom period. Because Lonicera pileata ‘Royal Carpet’ often roots where its low-flung branches touch the soil, it naturally spreads vigorously. This habit also means propagation is very easy using simple cuttings taken from healthy branches.
In colder portions of its range (like Zone 6), the plant might look semi-evergreen, but in warmer zones (Zone 8 and up), it remains reliably evergreen throughout winter. Assess your location to understand its expected winter foliage retention.
Landscape Uses
The primary role for Privet honeysuckle is as a robust, shrubby ground cover or for masking slopes and banks where traditional lawn care is impractical. Its stiff, horizontal branching system excels at stabilizing soil and preventing erosion. Lonicera pileata ‘Royal Carpet’ works wonderfully as a low underplanting beneath deciduous shade trees, creating lush visual texture where turf struggles.
For design purposes, use this five-to-eight-foot spreader to create strong visual lines or to transition between paved areas and perennial beds. Its dense habit effectively smothers weeds, reducing gardening effort significantly. It serves as an excellent non-flowering filler in woodland garden settings.
Consider pairing Lonicera pileata ‘Royal Carpet’ with plants that enjoy similar moisture and shade profiles, perhaps contrasting its glossy dark green leaves with plants featuring lighter or finer foliage. It provides an evergreen anchor throughout the year in mixed shrub borders.

Potential Problems
No serious insect or disease problems typically plague this tough variety of Privet honeysuckle. However, in particularly hot and humid summer climates, gardeners should watch for sporadic issues like powdery mildew or minor leaf spots. Should aphids appear, standard horticultural oils or insecticidal soaps are effective treatments. Maintaining good air circulation through appropriate initial spacing helps mitigate fungal development. Watch for aphids.

This dense ground cover typically achieves a mature height between 1 and 2 feet, spreading widely from 5 to 8 feet.
What sun exposure does Privet honeysuckle need?
It performs well in full sun but appreciates, and sometimes requires, part shade when planted in very hot summer climates to protect the foliage.
When does Lonicera pileata ‘Royal Carpet’ bloom?
The fragrant, yellowish-white flowers of the Privet honeysuckle can appear sporadically beginning in May and sometimes lasting until November, depending on seasonal variation.
Conclusion
The Lonicera pileata ‘Royal Carpet’ is an invaluable asset for landscape designers needing durable, low-growing, broadleaf evergreen coverage. Offering fragrant blooms set against glossy foliage and boasting low maintenance, this Privet honeysuckle excels on challenging sites like banks. Before planting, confirm your garden falls within USDA Zones 6-8 to ensure this long-lived ground cover establishes successfully.
Propagation Tips
Since Lonicera pileata ‘Royal Carpet’ naturally roots where its stems contact the soil, propagation by simple layering is highly effective. To encourage this, periodically peg down some of the horizontal branches onto the soil surface during the growing season. Alternatively, this shrub is easily grown from cuttings taken soon after the new growth matures.
Companion Planting
When selecting companions for Lonicera pileata ‘Royal Carpet’, focus on plants that similarly prefer well-drained soil and can handle varying light conditions from full sun to partial shade. In shadier woodland garden settings, contrast its dense texture with ferns or woodland phlox (Phlox divaricata). For sunny, dry banks where drought tolerance is key, consider pairing it with ornamental grasses or creeping thyme varieties that won’t aggressively compete for root space while maintaining a similar low profile.
