Plectranthus is a diverse genus with over 300 species of evergreen shrubs, ground covers, and trailing plants that captivate gardeners and collectors alike.
Known for their striking silver, variegated, or lush green foliage paired with attractive flower spikes, they suit a wide variety of garden styles and container displays.
Plectranthus are found in Australia as well as South Africa, in our opinion Australia has some of the best varieties of all. They offer unique landscape and conservation value, especially for plant enthusiasts interested in rare natives and decorative hybrids.
Highlighted Species and Collectors’ Favorites
- Plectranthus argentatus: A Silver Foliage Gem
Revered for its soft, silvery-grey leaves and compact, rounded habit, P. argentatus is a standout Australian native perfect for collectors who prize ornamental foliage. Its mauve flower spikes in spring provide elegant contrast, and its adaptability to pots and semi-shaded locations makes it a versatile choice. - Plectranthus ‘Mona Lavender’: The Decorative Hybrid
This popular hybrid combines glossy green leaves with long-lasting lavender-purple flowers, making it a favorite among collectors and landscape designers. Its compact size and flowering vigor make it ideal for containers, shaded garden beds, or as a feature plant.
Rare Australian Natives
- Plectranthus nitidus (Nightcap Plectranthus) is a threatened Queensland species prized by conservationists and collectors for its rarity and potential to enhance native plant gardens.
- Plectranthus graveolens exhibits pleasing green foliage and vibrant blue flower spikes ideal for woodland or understory plantings.
- Plectranthus apreptus and Plectranthus parviflorus (‘Blue Spires’) offer variegation and floral interest with blue flowers and mint-like foliage, ideal for subtropical gardens.
South African Species and Vigorous Covers
- Plectranthus ecklonii grows to 2m or more with dense purple to pink flower spikes, suited for collectors who want height and floral display. Cultivars include Hawthorne Pink and White
- Plectranthus ciliatus and Plectranthus australis (Swedish Ivy) are robust ground covers or hanging basket plants but can be invasive in some climates, so manage carefully.
- Plectranthus neochilus is commonly called Dogbane and is reputed to repel dogs…
Growing and Care for Collectors
- Site Selection: Most species thrive in part shade to dappled sunlight with protection from harsh afternoon heat.
- Soil and Drainage: Well-drained, fertile soil is essential. Raised beds or containers work well in wetter climates.
- Watering: Regular watering during establishment, easing in drought conditions.
- Pruning and Maintenance: Light pruning after flowering encourages bushier growth and maintains a neat shape. Monitor vigorous species to prevent unwanted spread.
- Containers: Hybrids like ‘Mona Lavender’ and silver foliage types such as P. argentatus excel in pots, allowing collectors to showcase these plants easily.
Companion Plants to Pair with Plectranthus
For a vibrant, textured garden, consider these complementary plants that share similar growing conditions and aesthetic appeal:
- Silver Lady Fern (Blechnum gibbum)
This Australian native fern offers soft, silver-green fronds that contrast beautifully with the velvety leaves of P. argentatus. Both enjoy part shade and well-drained soils, creating a layered, woodland effect. - Native Kunzea species
Compact and fragrant shrubs like Kunzea ambigua complement the Plectranthus leaf texture and add floral interest with their soft pink or white flower clusters. Ideal for wildlife-friendly gardens including pollinators. - Epimedium species
Known for their ornamental foliage and delicate flowers, Epimediums thrive in similar semi-shaded garden settings. Their variegated leaf forms and unique spring flowers blend well with Plectranthus foliage and growth habits. - Tropical Hibiscus (Hibiscus rosa-sinensis)
For a splash of bold flower color near shaded beds of Plectranthus, tropical hibiscus adds vertical interest and contrasting large blooms, thriving under partially sheltered conditions. - Coleus (P. scutellarioides)
A close relative within the Plectranthus genus, coleus offers vivid leaf variegations and colors that provide a strong accent when planted near mixed Plectranthus species or hybrids such as ‘Mona Lavender’.
