An Amateur Gardening report published Nov. 8 lists seven plants garden designer Fi Boyle recommends for sloping beds, from evergreen periwinkle to drought-tolerant trailing rosemary. Boyle says gardeners should match plants to their site’s aspect and soil; the report does not compare their performance in trials.
Garden designer Fi Boyle has recommended seven plants for sloping gardens, including hardy geranium, lesser periwinkle, ground cover roses and trailing rosemary, in a report published by Amateur Gardening on Nov. 8. The choices offer different combinations of ground cover, seasonal flowers and foliage, but Boyle says gardeners should first match plants to their site’s soil and aspect.
Boyle, of Fi Boyle Garden Design, recommends ground-cover plants as one way to disguise bare patches on sloped flower beds. The report says she has experience designing for slopes at an award-winning garden on a former quarry. Her list covers plants with varied light and soil preferences, rather than a single mix intended for every bank.
Geranium macrorrhizum is described as tolerant of dry shade and a range of soils, with summer fuchsia-pink flowers and foliage that adds autumn interest. Vinca minor, or lesser periwinkle, is evergreen and mat-forming; in suitable conditions, it may flower from spring into September. The report says sunnier positions can produce more flowers, and that the plant needs well-drained soil.
Ajuga reptans is presented as a pollinator-friendly option for moist clay or loam, though the report cautions against placing it too close to other mat-forming plants because it can compete with them. Ground cover roses suit full sun to light shade and well-drained soil, but Boyle says they need moisture; mulch can help retain it. Mexican fleabane is recommended for sunny, well-drained sites and coastal gardens, while trailing rosemary suits sunny conditions and is described as fairly drought-resistant. Sedum spurium can form a red-flowering summer carpet and is listed for well-drained chalk, loam or sand.
Matching Plants to Slopes
Sloped beds can leave patches of exposed soil and may be harder to plant and maintain than level ground. Boyle’s recommendations give gardeners a set of options for covering soil while adding flowers, foliage or fragrance across different seasons. The list also makes clear that the same plant will not suit every bank: shade, sun, drainage and moisture can affect whether a planting thrives.
The practical value is in choosing by conditions, not simply by colour. A gardener with dry shade might consider hardy geranium, while a sunny, free-draining slope could suit trailing rosemary or sedum. These are suggestions from a garden designer, not comparative trial results, and the report does not promise that any plant will prevent erosion or eliminate maintenance.

Boyle’s Site-First Advice
The report frames its seven selections around the challenges of planting on a slope, particularly the need to cover bare areas. It says Boyle has designed an award-winning garden on a former quarry site, providing the background for her advice on sloping gardens.
Her central guidance is to understand the site before buying plants. The report identifies soil type and aspect—the direction and exposure of the planting area—as factors to check. It does not provide a single planting plan or recommend using all seven plants together; some, including ajuga, may compete with other spreading ground covers.
“What works depends so much on the aspect and soil. The key is to match the plant to its surroundings, otherwise it won’t thrive and will need a lot of care.”
— Fi Boyle, Fi Boyle Garden Design, quoted by Amateur Gardening
Limits of the Plant Guide
The report gives general growing conditions but does not specify how the plants perform across different climates, slope gradients or local soil variations. It also does not provide trial data comparing their spread, durability or maintenance needs, so the recommendations should not be read as guarantees for a particular garden.
Some details depend on variety and conditions. The height and spread of ground cover roses are listed as varying by variety, and the report says periwinkle flowers for an extended period only in suitable conditions. It does not set out a site-specific planting scheme, spacing plan or advice on managing possible competition among spreading plants.
Check Conditions Before Planting
Gardeners considering the list can begin by checking the slope’s sun exposure, soil type and drainage, then compare those conditions with each plant’s stated needs. The report suggests practical care steps including mulching roses to retain moisture, watering ajuga during drought, deadheading hardy geranium and allowing Mexican fleabane to self-seed in cracks.
Boyle’s list is a starting point rather than a universal prescription. The next step for any individual garden is to choose plants suited to its conditions and account for how far mat-forming varieties may spread. The report does not announce a follow-up study or give a schedule for further recommendations.
Key Questions
Which plants does Fi Boyle recommend for a sloping garden?
Her seven recommendations are Geranium macrorrhizum, Vinca minor, Ajuga reptans, ground cover roses, Erigeron karvinskianus, Rosmarinus ‘Prostratus’ and Sedum spurium.
What should gardeners check before choosing plants?
Boyle says to assess the site’s aspect and soil. The report also gives plant-specific guidance on moisture and drainage, which can help narrow the choices.
Which plants in the list suit dry or sunny slopes?
The report describes hardy geranium as tolerant of dry shade and trailing rosemary as fairly drought-resistant. Mexican fleabane and sedum are listed for full sun and well-drained soil; local conditions still matter.
Can all seven plants be planted together?
The report does not recommend a single combination. It specifically cautions that Ajuga reptans can compete with other mat-forming plants, so gardeners should account for spreading growth when planning a bed.
