Amateur Gardening published a list of seven plants recommended by garden designer Fi Boyle for sloping gardens. The choices include ground-covering perennials, roses, Mexican fleabane, prostrate rosemary and sedum, but Boyle says gardeners should match plants to their soil and the slope’s 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 8 November 2026. Her selections range from shade-tolerant geranium to sun-loving rosemary and sedum, with the advice that gardeners should choose according to their site’s soil and aspect.
Boyle, of Fi Boyle Garden Design, recommends ground-cover plants to help disguise bare patches of soil on sloped beds. The report says her experience includes an award-winning garden on a former quarry. Boyle cautions that there is no single plant list suited to every bank: soil type and aspect affect which choices will thrive and how much care they need.
The seven selections are Geranium macrorrhizum, which can grow in sun or shade and tolerate dry shade; evergreen Vinca minor, suited to sun or partial shade in well-drained soil; and Ajuga reptans, which prefers moist clay or loam and may compete with other mat-forming plants. Boyle also suggests ground-cover roses for sunny to lightly shaded positions, noting that they need some moisture.
The remaining options are Erigeron karvinskianus, a full-sun, well-drained-site choice that can self-seed; fragrant, drought-resistant Rosmarinus ‘Prostratus’, also for full sun; and Sedum spurium, which forms a low carpet in sunny, well-drained conditions. The report gives different flowering periods and growing tips for each, including dividing ajuga every few years and cutting back sedum flowers after they fade.
Matching Plants to Slope Conditions
Sloping beds can leave exposed soil and may be harder to plant and maintain than level ground. Boyle’s recommendations offer gardeners a range of plants with spreading growth, but the report does not present them as a universal fix. Matching each plant to light, soil and moisture is central to the advice: a plant that struggles in its position may need more care and fail to provide the intended cover.
The list also shows that the options serve different purposes. Evergreen periwinkle can provide foliage through the year, while sedum and geranium offer seasonal flowers and foliage interest. Mexican fleabane is described as attractive to bees, and rosemary adds fragrance. These are reported characteristics, not guarantees for every garden; results depend on local growing conditions.

Seven Choices for Different Sites
The Amateur Gardening report presents the plants as a selection for different garden situations, rather than a ranked list. Geranium macrorrhizum is described as adaptable across soil types and sun or shade, while periwinkle needs well-drained soil and may flower more heavily in sunnier spots. Ajuga is recommended for partial shade or full sun with moist clay or loam, and the report advises giving it room away from other vigorous mats.
For drier, sunny areas, Boyle points to prostrate rosemary and sedum, both listed for chalk, loam and sand. Ground-cover roses can tolerate poor soil and exposed areas, but need moisture and benefit from mulch, according to the report. Erigeron is suggested for coastal gardens and can seed itself into cracks. The article also refers readers to a separate feature about Boyle’s former quarry garden.
““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, garden designer, as quoted by Amateur Gardening
Site Conditions Still Matter
The report does not identify a single best plant for all slopes or provide a planting plan for a particular garden. Local soil, drainage, exposure and available light will determine which recommendations are suitable. It also does not give a universal planting density, establishment schedule or maintenance workload for the seven choices.
Some descriptions are conditional: periwinkle may flower from spring into September in suitable conditions, and ground-cover roses need moisture to thrive. The article does not quantify how quickly any plant will cover a bank or how well it will control erosion. Gardeners should treat the listed heights and spreads as guidance, especially where the source says growth depends on variety.
Check the Bank Before Planting
The next step for gardeners is to assess the slope’s sun exposure, soil and drainage before choosing plants, following Boyle’s guidance. They can then use the report’s growing notes to narrow the options, allowing for moisture needs, spreading habits and flowering seasons. For example, the article recommends watering ajuga during drought, mulching roses to retain moisture and allowing erigeron to self-seed in cracks.
The source provides no follow-up announcement or schedule for further updates. Its practical recommendation is to make plant choices around the site rather than assume all seven will suit every bank.
Key Questions
Which plants does Fi Boyle recommend for sloping gardens?
The seven are Geranium macrorrhizum, Vinca minor, Ajuga reptans, ground-cover roses, Erigeron karvinskianus, Rosmarinus ‘Prostratus’ and Sedum spurium.
Which of the listed plants can grow in shade?
The report says Geranium macrorrhizum can grow in sun or shade, including dry shade. Vinca minor suits sun or partial shade, while ajuga is listed for partial shade or full sun.
Which plants are suggested for sunny, dry areas?
Boyle describes prostrate rosemary as fairly drought-resistant and recommends it for full sun. Sedum spurium also suits full sun and well-drained soil. The report stresses that local conditions still matter.
Do the recommendations guarantee erosion control?
No. The report recommends ground-cover plants to disguise bare soil, but it does not claim that any of the seven will prevent erosion or provide a particular level of bank stabilization.
