| Ground Cover Charm: Campanulas and Sagina for Tricky Garden Spots I was asked the other day what Campanulas I would use for ground cover. The client in question has a tricky spot in her garden that surrounds the base of a garden statue—an area that has never grown well and often appears bare. I suggested planting a mixture of Sagina (pearlwort) and Campanula (bellflower) to soften the space and provide lush, flowering coverage throughout the season. |
| Here’s a deeper look at the best Campanulas for UK ground cover—and how they pair beautifully with Sagina to create a resilient and enchanting planting combo. |
| Best Ground Cover Campanulas for UK Gardens Campanula portenschlagiana – Quick-spreading and ideal for rockeries and edging Campanula poscharskyana – Cascading and long-flowering, perfect for walls and steps Campanula cochlearifolia – A petite, fairy-like option for cool, shaded spots Sagina subulata (Irish Moss or Pearlwort) This ultra-low grower creates a vibrant, moss-like base layer. Its fine texture contrasts nicely with Campanula’s more open form and gives the planting a cohesive, finished feel. Bonus: it’s evergreen and peppered with tiny white flowers in summer. Why Combine Sagina and Campanula? Textural layers: Sagina hugs the ground, Campanulas trail and cluster slightly higher Evergreen + flowering: Year-round interest with seasonal floral peaks Good for pollinators: Both attract insects, especially bees and hoverflies Low-maintenance: All thrive with minimal fuss once established |
| Design Idea: Planting Around a Garden Statue Inner base: Campanula cochlearifolia for soft height and seasonal colour Sagina subulata to form a permanent green carpet Middle ring: Campanula portenschlagiana for denser coverage Add tufts of Thymus serpyllum (Creeping Thyme) for scent and extra blooms Outer edges or cracks: Campanula poscharskyana trailing outward Combine with Erigeron karvinskianus (Mexican Fleabane) for frothy daisy-like flowers |
| Other Easy Layered Companions to Try To enhance the layered effect and extend seasonal appeal, consider mixing in these additional small-scale, ground-hugging plants: Thymus serpyllum (Creeping Thyme) Height: 3–8 cm Flowers: Pink/purple in summer Scented foliage, great for bees, tolerates light foot traffic Perfect between stones or bordering Sagina Erigeron karvinskianus (Mexican Fleabane) Height: 15–30 cm Flowers: Dainty white daisies fading to pink, June–October Soft and informal, great with Campanula for long flowering Ajuga reptans’ Chocolate Chip’ (Bugleweed) Height: 5–10 cm Flowers: Spikes of deep blue in spring Glossy bronze foliage adds rich tone beneath lighter plants Excellent in shade or partial shade Sedum acre (Golden Moss Sedum) Height: 5 cm Flowers: Yellow stars in early summer Tough and drought-tolerant, ideal for sunny dry spots Tiarella cordifolia (Foamflower) Height: 15–30 cm Flowers: Airy white or pink spires in spring For shadier areas, combines well with Campanula in woodland edges |
| Tips for Layered Ground Cover Success Plant in drifts or repeating clusters to make it look natural and cohesive Mix evergreen and deciduous varieties for year-round structure Use similar soil and moisture lovers together to keep maintenance simple Let plants knit together—allow space at first, but let them fill in over time |
| Whether you’re filling a difficult gap under a garden ornament or designing a soft-edged path, combining Sagina with low-growing Campanula and a few thoughtful companions can transform bare ground into a vibrant, living patchwork. |
A Gardener's Curiosity 
I am loving that Sagina, but I doubt our local nurseries have it. Where can I get some?

Hi Jaye, l got mine from my local nursery here in Sandwich. But you could probably buy it online if you don’t have a nursery near you.
