Description How to Grow More Info Delivery Reviews

Our ground cover collection of hardy herbaceous perennials brings so many benefits, which all lead to one thing: low maintenance gardening. We've selected some of our best low-growing perennials to offer a range of planting solutions. Use them as front of border plants in large sunny borders or set them in dappled shade as underplanting to trees and shrubs. You can even try them in pots and use your new perennial containers alongside seasonal pots. Every plant in the mix offers a controlled spreading habit, helping to quickly fill borders, cover soils and prevent weeds taking hold. And less weeding leads to more time spent enjoying your garden!

  • Perennial Ground Cover Collection comprises:
  • Arabis 'Lotti Pink' - A spring flowering, cushion-like perennial.
  • Armeria 'Ballerina Mixed' - Dense cushions of bright green foliage produce spherical flower heads set atop sturdy upright stems.
  • Dianthus deltoides 'Red' - Neat clumps of silver green foliage that makes stunning ground cover.
  • Campanula 'Dwarf Blue' - Cushion-like plants, which are smothered in violet-blue flowers through the summer months.
  • Aubrieta 'Mixed' - These tough little plants will thrive in the poorest of soils, forming dense mats of evergreen foliage.
  • Erigeron 'Stallone' - This cheery clump forming perennial enjoys light sandy soils, making it ideal for coastal gardens.

Powerliner® plugs are well established, mature plugs which can be potted on or can be planted straight into the border or containers. Each plug module is 6.5cm in diameter.

In autumn, cut back the old foliage to ground level and apply a mulch of well rotted manure or garden compost to the base of the plants. Lift and divide overcrowded clumps of perennials in autumn to maintain their vigour.
Pot up plants and grow them on in frost free conditions until all risk of frost has passed. When plants are well grown, gradually acclimatise them to outdoor conditions over 7 to 10 days before transplanting into borders and containers. The herbaceous perennials in this collection can be grown in any moist, fertile soil, in sun or semi shade. Work some compost or general fertiliser into the top 20cm of the soil prior to planting.
