Amateur Gardening published a guide on 8 November 2026 featuring seven plants recommended by garden designer Fi Boyle for sloping beds. The list includes ground covers suited to different conditions, but Boyle stresses that gardeners should match plants to their site’s soil and aspect.
Garden designer Fi Boyle has recommended seven plants for adding colour and ground cover to sloping gardens in a guide published by Amateur Gardening on 8 November 2026. Her choices range from dry-shade-tolerant geranium to sun-loving rosemary and sedum, with Boyle advising gardeners to check their soil and the slope’s aspect before planting.
Boyle, of Fi Boyle Garden Design, recommends ground-cover plants to help disguise bare patches on sloped beds. The guide says her experience includes an award-winning garden on a former quarry. Boyle cautions that plant performance depends on local conditions: a poor match can fail to thrive and require more care.
The list includes Geranium macrorrhizum, which can form a semi-evergreen mat and tolerates dry shade, and Vinca minor, an evergreen ground cover that may flower from spring into September in suitable conditions. Ajuga reptans is described as pollinator-friendly, but the guide warns it may compete with nearby mat-forming plants and advises watering during drought.
For flowers, the recommendations include ground-cover roses, which need moisture, and Erigeron karvinskianus, a sun-loving plant that can self-seed and is suggested for coastal gardens. Rosmarinus ‘Prostratus’ offers fragrance and drought resistance, while Sedum spurium can form a red-flowering carpet in summer and suppress weeds. The guide gives different soil, light and care notes for each plant rather than presenting them as suitable for every slope.
Choosing Plants for Slope Conditions
Sloping beds can leave exposed soil and make plant selection more dependent on drainage, moisture, light and soil type. Ground-covering growth can help fill gaps, while flowers and foliage bring seasonal interest. Boyle’s recommendations offer several options, but the guide’s central advice is to choose for the site rather than assume one planting scheme will work across all slopes.
The distinctions matter in practice: roses need moisture, while prostrate rosemary is presented as relatively drought-resistant and suited to full sun. Vinca needs well-drained soil, and ajuga prefers moist clay or loam. These are specific growing suggestions, not guarantees of performance; local conditions and the chosen variety can affect results.

Seven Choices for Different Sites
The recommendations cover plants with differing heights, spreads and growing habits. Geranium macrorrhizum is listed as 10 to 50 centimetres tall, with a spread of 50 centimetres to 1 metre. Vinca minor can spread from 10 centimetres to 1.5 metres, according to the article. The guide says sunny positions can produce more vinca flowers.
Other care notes include deadheading geranium, dividing ajuga every few years, mulching roses to retain moisture and taking rosemary cuttings in summer. For sedum, the guide advises cutting back spent flowers and lifting and dividing plants in spring. These recommendations come from the Amateur Gardening report; they do not replace checking the needs of a particular cultivar or 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, Fi Boyle Garden Design, as quoted by Amateur Gardening
What Depends on Local Conditions
The article does not identify a single best plant for all slopes or provide results from comparative trials. It also does not specify the conditions of an individual reader’s garden, including its soil drainage, exposure, moisture and shade. Those details affect which recommendations are likely to work.
Spread and flowering can vary by variety and growing conditions. The guide gives broad ranges for several plants, but those figures should not be read as guaranteed sizes or flowering periods for every garden. Gardeners may need to check the requirements of plants available locally before buying or planting them.
Match the List to Your Garden
The immediate next step for gardeners is to assess the slope’s light and soil, then narrow the list to plants suited to those conditions. For example, the guide points to geranium for dry shade, rosemary and sedum for sunny, well-drained sites, and ajuga for moist clay or loam. Where conditions are uncertain, checking drainage and observing how much sun the bank receives can help inform the choice.
Amateur Gardening also directs readers to a separate feature on Boyle’s former quarry garden. The published guide gives planting suggestions, but it does not report a new trial, product launch or follow-up results; the longer-term performance of plants will depend on individual sites and care.
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 tolerate dry shade?
The report describes Geranium macrorrhizum as tolerant of dry shade and a range of soil types. Boyle’s broader advice is to match any plant to the slope’s conditions.
Which recommendations are suited to full sun?
The guide lists Erigeron karvinskianus, Rosmarinus ‘Prostratus’ and Sedum spurium for full sun. Ground-cover roses are listed for full sun to light shade.
Do all seven plants need the same care?
No. The article gives different guidance: roses need moisture, ajuga may need water during drought, and sedum prefers well-drained soil. Care should be based on the plant’s requirements and the garden’s conditions.
