ground cover plants with blue flowers

Why Choose Blue-Flowering Ground Covers?

Ground cover plants with blue flowers not only create striking visual effects, but they’re also hardworking plants. The cool blue blooms add depth and contrast to gardens dominated by green and warm tones, and their low growth habit keeps soil moist while thwarting weeds. Blue-flowering ground covers blend beautifully with silver-leafed or white-flowering companions, creating serene and sophisticated planting schemes.

Top Choices for Ground Cover Plants with Blue Flowers

Ajuga 'Catlins Giant'

For vibrant blue flower spikes in spring and lush, glossy foliage year-round, Ajuga 'Catlins Giant' is a favourite among Kiwi gardeners. Its vigorous spreading nature makes it perfect for quickly covering shady areas, woodland gardens, or underplanting beneath shrubs and trees.

Pimelea prostrata 'Blue Peter'

Native to New Zealand, Pimelea prostrata 'Blue Peter' forms a dense mat of soft, silvery foliage, accented with dainty pale blue flowers in spring and summer. This hardy coastal ground cover tolerates salt spray and wind, making it an excellent choice for exposed gardens and retaining walls.

Isotoma fluviatilis

Also known as swamp isotome or blue star creeper, Isotoma fluviatilis is a delicate yet tough creeper. It creates a lush carpet of tiny blue star-shaped blooms from spring through summer. Ideal for between pavers or as a lawn alternative, it quickly fills gaps with its fine foliage and flowers.

Plumbago Royal Cape

If you’re after a bolder blue, Plumbago Royal Cape features clusters of vivid sky-blue flowers from summer into autumn. Although technically a sprawling shrub, it can be pruned low as a ground cover in larger spaces or allowed to cascade over walls for dramatic effect.

Dianella Blue Twist

For a unique twist on classic ground covers, Dianella Blue Twist offers spiky blue-green foliage and clusters of small, blue star-shaped flowers above the leaves. It’s drought tolerant and brilliant for mass planting in both sun and part shade.

Planting and Care Tips

When choosing ground cover plants with blue flowers, consider the light and soil conditions in your garden. Most blue-flowering ground covers prefer moist, well-drained soil and either sun or part shade. Space your plants correctly to allow for spreading, and mulch around them to retain moisture and suppress weeds. Regular watering and a light feed in spring will encourage lush foliage and generous flowering.
