A November 8, 2026, Amateur Gardening report lists seven plants garden designer Fi Boyle recommends for covering and adding seasonal interest to sloping beds. Her choices range from shade-tolerant geranium to sun-loving rosemary and sedum; she says gardeners should match plants to their soil and aspect.
Garden designer Fi Boyle has recommended seven plants for adding colour and ground cover to sloping gardens, in a report published by Amateur Gardening on November 8, 2026. The list includes options for different light and soil conditions, from dry-shade-tolerant hardy geranium to sun-loving sedum, while Boyle stresses that plants should be selected to suit a site’s particular conditions.
Boyle, of Fi Boyle Garden Design, recommends ground-cover plants as a way to disguise bare soil on sloped beds. Her suggestions are Geranium macrorrhizum, lesser periwinkle (Vinca minor), bugle (Ajuga reptans), ground-cover roses, Mexican fleabane (Erigeron karvinskianus), prostrate rosemary (Rosmarinus ‘Prostratus’) and Sedum spurium. The report describes the plants as choices for a range of garden situations, not as a single planting plan for every slope.
The plants vary in their needs and growth habits. Boyle’s list includes dry-shade-tolerant geranium for a range of soils, while periwinkle is evergreen and can flower from spring into September in suitable conditions. Bugle is described as pollinator-friendly, but the report cautions that it can compete with other mat-forming plants. Ground-cover roses need some moisture, and the recommended rosemary and sedum favour sunny, well-drained sites.
Other details in the report include seasonal flowers and practical care tips. Mexican fleabane flowers from May to October and can self-seed; rosemary is fragrant and fairly drought-resistant; sedum can form a red carpet in summer and suppress weeds. The suggested maintenance includes watering bugle during drought, mulching roses to retain moisture, and cutting back sedum flowers after they fade.
Matching Plants to Slopes
Sloping beds can leave patches of exposed soil and make plant choice more dependent on local conditions. The recommendations offer gardeners a range of ground-covering forms and flowering periods, alongside evergreen foliage or seasonal colour. The practical value is in comparing each plant’s stated needs with the slope’s sun exposure, soil and drainage before buying or planting.
The list also makes clear that ground cover is not automatically low-maintenance in every position. Roses need moisture, bugle may compete with nearby spreading plants, and periwinkle requires well-drained soil. Choosing plants that suit the site may reduce the amount of corrective care needed, but the report does not promise that any plant will thrive on every slope.

Boyle’s Site-Based Advice
Boyle’s recommendations draw on her work designing sloping gardens, including an award-winning garden on a former quarry, according to Amateur Gardening. The report presents her choices as a selection for different conditions rather than a ranked list or a prescribed combination. It also points readers to a separate feature about ideas from the quarry garden.
Her central advice is to check both soil type and aspect before choosing plants. That matters across the seven options: some tolerate shade or several soil types, while others are listed for full sun or particular soil conditions. The source gives approximate heights and spreads for most plants, but notes that the size of ground-cover roses depends on the variety.
“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
Site Conditions Still Matter
The article does not provide a single planting layout, detailed spacing plan or cost estimate for the seven plants. It also does not specify how each choice performs on steep slopes or in every regional climate. Boyle’s guidance is conditional: gardeners need to assess their own soil, aspect, drainage and moisture before deciding what to plant.
Several recommendations also depend on variety or growing conditions. Ground-cover rose height and spread vary, and periwinkle’s longer flowering period is described as possible in the right conditions. The report does not give comparative trials or quantify how much soil coverage each plant provides.
Check Conditions Before Planting
The next step for gardeners is to identify the slope’s light levels and soil characteristics, then compare them with each plant’s stated requirements. They can also plan for how widely spreading plants may interact: Boyle’s list specifically warns against placing bugle too close to other mat-formers. The source recommends care suited to individual plants, including spring propagation by division for bugle and summer cuttings for rosemary.
Amateur Gardening also directs readers to further material on Boyle’s former quarry garden. No additional announcement or follow-up timetable is given in the report.
Key Questions
Which plants does Fi Boyle recommend for sloping gardens?
Boyle recommends hardy geranium, lesser periwinkle, bugle, ground-cover roses, Mexican fleabane, prostrate rosemary and sedum. The report presents them as options for differing conditions, rather than a set that should all be planted together.
Which of the listed plants can grow in shade?
Geranium macrorrhizum is listed for sun or shade. Lesser periwinkle is listed for sun or partial shade, while bugle suits partial shade or full sun. The report advises checking the conditions of the specific site.
Which choices are suited to sunny, dry conditions?
Prostrate rosemary is described as fairly drought-resistant and suited to full sun. Sedum also prefers full sun and well-drained soil. Mexican fleabane is listed for full sun and well-drained soil, but the report does not describe it as drought-resistant.
Do the recommendations need ongoing care?
Yes. The report suggests, among other tasks, watering bugle during drought, mulching ground-cover roses to retain moisture and cutting back sedum flowers after they fade. Boyle says plants need to be matched to their surroundings to avoid requiring a lot of care.
