The Ultimate Guide to Growing and Caring for Creeping Rosemary

Introduction to Creeping Rosemary

Creeping rosemary (Rosmarinus officinalis ‘Prostratus’) is a versatile and aromatic herb that adds beauty and functionality to gardens and landscapes. This low-growing, evergreen shrub is renowned for its trailing habit, making it an excellent choice for ground cover, cascading over walls, or spilling out of containers. This comprehensive guide will delve into everything you need to know about growing and caring for creeping rosemary, from its basic characteristics to advanced care tips.

Characteristics of Creeping Rosemary

Creeping rosemary is a hardy perennial that belongs to the mint family, Lamiaceae. Its needle-like, dark green leaves and small, pale blue lavender flowers that bloom in late spring and early summer characterize creeping rosemary. Here are some key features of this plant:

  • Growth Habit: As its name suggests, creeping rosemary has a prostrate growth habit, spreading horizontally rather than growing upright. It typically reaches a height of 6-12 inches and can spread up to 3-5 feet wide.
  • Foliage and Flowers: The aromatic foliage is rich in essential oils, making it a favorite for culinary and medicinal uses. The flowers attract pollinators like bees and butterflies, adding biodiversity to your garden.
  • Hardiness: Creeping rosemary is hardy in USDA zones 7-11, tolerating temperatures as low as 20°F (-6°C). Gardeners in colder regions have the option to grow creeping rosemary as an annual or in containers that they can bring indoors during winter.

Trailing Rosemary Plant Information

Trailing, or creeping, rosemary is a unique cultivar derived from herbaceous shrubs of Mediterranean provenance. This evergreen perennial can be effectively trained over fences, rockeries, and elevated beds, providing an aesthetically pleasing ground cover over time with its fine, leathery foliage and delicate flowers. Rosemary groundcover offers fragrant foliage that not only diminishes weed growth but also serves as an excellent complement to other drought-resistant landscape plants. Rosemary is an exemplary xeriscape plant with high drought tolerance once established, harmonizing well with other perennial herbs and drought-tolerant species.

Prostrate rosemary plants can attain heights up to 3 feet (91 cm) and span widths of 4 to 8 feet (1-2 m), with splendid trailing stems that gracefully arch and possess a beneficial draping quality. The leaves are leathery, a pale grayish-green hue, and exude a pungent scent and flavor. This groundcover is hardy in USDA zones 8 to 10 but can be cultivated in colder regions using containers and brought indoors during winter. Rosemary has a myriad of uses, from culinary applications to decorative purposes, and has historically been believed to enhance memory.

Cultivation of Creeping Rosemary

To cultivate creeping rosemary successfully, it is imperative to ensure exceptional drainage, as these plants are highly susceptible to root rot in saturated conditions. While established plants can thrive in compacted soil, young plants require loose soil to foster root growth. In compacted soils, aerate the root zone to enhance porosity and facilitate oxygen access to the roots.

Prostrate rosemary plants, native to the arid regions of the Mediterranean, necessitate well-drained soil and even thrive in areas with low fertility. Plant them in light, porous soil, incorporating sand or grit as needed to improve drainage. The shrub performs admirably in containers, but caution is advised to avoid overwatering. Allow the soil to dry out completely before adding moisture.

Select a location that provides six to eight hours of bright sunlight. Growing rosemary indoors can be challenging; therefore, place container plants in a sunny spot where humidity is low. In transitional zones, plant the herb in a sheltered location and apply heavy mulch around it, covering the plant at night during cold spells to help it survive light freezes. If some stems succumb to cold weather, prune them off and encourage new growth from the base. Light pruning can promote branching, and you can also train the plant over a structure for an appealing effect. Rosemary groundcover can be left to spread over rocks and other areas as an effective herb barrier and attractive living mulch.

Planting Creeping Rosemary

Site Selection

Choosing the right location is crucial for the success of creeping rosemary. It thrives in full sun, requiring at least 6-8 hours of direct sunlight per day. Well-drained soil is essential to prevent root rot, a common issue with rosemary. Slightly acidic to neutral soil (pH 6.0-7.5) is ideal.

Soil Preparation

Before planting, amend the soil with organic matter such as compost to improve drainage and fertility. If your soil is heavy clay or retains too much moisture, consider planting creeping rosemary in raised beds or containers.

Planting Steps

  1. Digging the Hole: Dig a hole twice as wide and as deep as the root ball of the plant.
  2. Positioning: Place the plant in the hole, ensuring the top of the root ball is level with the soil surface.
  3. Backfilling: Fill the hole with soil, gently firming it around the roots to eliminate air pockets.
  4. Watering: Water thoroughly after planting to help settle the soil and establish the roots.

Caring for Creeping Rosemary


While creeping rosemary is drought-tolerant once established, it requires regular watering during the first growing season. Water deeply and infrequently, allowing the soil to dry out between waterings. Overwatering can lead to root rot, so ensure proper drainage.


Rosemary Plant does not need heavy feeding. A light application of balanced, slow-release fertilizer in spring is sufficient. Too much fertilizer can reduce the essential oil content of the leaves, diminishing their aromatic and culinary qualities.

Pruning and Maintenance

Regular pruning helps maintain the shape and vigor of creeping rosemary. Prune after flowering to encourage new growth and prevent the plant from becoming woody and leggy. Remove any dead or diseased branches promptly to improve air circulation and reduce the risk of fungal infections.

Propagation of Creeping Rosemary

Propagation of Creeping Rosemary


One of the easiest methods to propagate creeping rosemary is through cuttings. Here’s how:

  1. Select Healthy Shoots: Choose non-flowering shoots about 4-6 inches long.
  2. Prepare the Cuttings: Remove the lower leaves, leaving a few at the top.
  3. Rooting Medium: Dip the cut end in rooting hormone and plant it in a pot filled with a well-draining mix of sand and perlite.
  4. Environment: Keep the cuttings in a warm, bright location, out of direct sunlight. Maintain humidity by covering the pot with a plastic bag or placing it in a propagation chamber.
  5. Root Development: Roots should develop in 4-6 weeks. Once rooted, transplant the new plants into individual pots or directly into the garden.


Growing creeping rosemary from seeds is more challenging and time-consuming compared to cuttings. Germination rates can be low, and the process may take several weeks. If you choose this method, start seeds indoors 10-12 weeks before the last frost date and transplant seedlings outdoors after the risk of frost has passed.

Common Pests and Diseases


  • Aphids: These tiny insects can suck the sap from young shoots, causing distorted growth. Control them with insecticidal soap or neem oil.
  • Spider Mites: These pests thrive in hot, dry conditions and can cause stippling and webbing on the foliage. Regular misting and introducing beneficial predators like ladybugs can help manage spider mites.


  • Root Rot: Caused by overwatering and poor drainage, root rot can be fatal to creeping rosemary. Ensure proper soil conditions and avoid waterlogged areas.
  • Powdery Mildew: This fungal disease appears as a white, powdery coating on leaves. Improve air circulation and apply fungicidal sprays if necessary.

Culinary and Medicinal Uses

Creeping rosemary is not only ornamental but also highly valued for its culinary and medicinal properties. The leaves can be harvested year-round for use in cooking, providing a fresh, piney flavor to a variety of dishes, from roasted meats to breads and salads. Medicinally, rosemary has been used for centuries to improve memory, relieve muscle pain, and boost the immune system.


Creeping rosemary is a beautiful and practical addition to any garden. With its aromatic foliage, attractive flowers, and low-maintenance care requirements, it is an ideal choice for both novice and experienced gardeners. By following the guidelines outlined in this article, you can ensure your creeping rosemary thrives, providing years of enjoyment and utility.
