Living mulch plants are a game-changer for gardeners seeking to reduce their water usage and suppress weeds. These plants, often flowering groundcover varieties or nitrogen-fixing annuals, offer a natural and sustainable approach to gardening. They provide a protective layer around the base of other plants, conserving soil moisture and enriching it with nutrients. Julian Palphramand, head of plants at British Garden Centres, highlights the practicality of these plants, stating that they 'do the work of a traditional mulch without the need for bags of bark or compost.'
One standout living mulch plant is Aubrieta, a popular perennial that flourishes in spring with its vivid purple blooms. Its dense foliage throughout the year makes it an excellent groundcover for weed suppression and soil moisture conservation. The 'Purple Cascade' F1 variety from Thompson & Morgan is a personal favorite for its striking color. Julian praises Aubrieta's ability to spread quickly, forming a dense mat that suppresses weeds and adds natural beauty to sunny borders. It's a low-maintenance, usually evergreen or semi-evergreen plant, making it a top choice for gardeners.
Clover, a popular green manure plant, is another excellent living mulch option. Garden designer Zoe Claymore recommends sowing clover after a heatwave and rain to fix nitrogen in the soil. Many gardeners prefer green manures over traditional mulch for their nutrient-boosting properties. Amazon and Thompson & Morgan offer packs of white clover seeds and green manure seeds, respectively, making it easy to incorporate into your garden.
Creeping thyme is a natural choice for sunny, dry spots, creating a low, walk-on carpet that holds moisture and keeps roots cool. Julian suggests growing creeping thyme in these areas, and even exploring the idea of a creeping thyme lawn, which requires less watering than traditional grass. Crocus and B&Q provide 'Pink Chintz' and 'Archers Gold' varieties, respectively, offering both fragrance and golden foliage.
Nasturtiums, with their trailing stems and large leaves, are fast-growing annuals that excel as living mulch plants. Horticultural expert Richard Barker recommends planting them around plants with deep root systems to avoid competition for nutrients. Amazon and Thompson & Morgan offer Fothergill's 'Oh Sow Simple' 'Nasturtium Mix' seeds and 'Purple Emperor' nasturtiums, respectively, allowing gardeners to enjoy their benefits.
Periwinkle, particularly the lesser periwinkle (Vinca minor), is a fast-growing groundcover that blankets areas with dense foliage. Julian recommends it for shade or under trees, as it establishes quickly and fills gaps in the garden. Crocus and Gardening Express offer 'Bowles's Variety' and 'Illumination' periwinkle, respectively, providing gardeners with options for striking golden foliage.
In conclusion, living mulch plants offer a natural and effective way to nurture and protect gardens. From Aubrieta's vibrant blooms to the versatility of clover and the natural beauty of creeping thyme, these plants provide a sustainable and low-maintenance approach to gardening. By incorporating these living mulch plants into your garden, you can enjoy a healthier, more drought-resistant, and visually appealing outdoor space.
