A low-growing perennial with trailing stems, rounded green leaves and yellow summer flowers. Useful as ground cover or for softening container edges.

Why we like it

• Trailing ground-cover growth
• Yellow summer flowers
• Useful at the edge of a damp border

What to know

• Grow in sun or partial shade; some shade helps prevent drying in hot weather.
• Choose moist soil; suitable near a pond edge, without submerging a normal nursery pot.
• Water containers regularly, as thin trailing stems wilt when dry.
• Trim runners to keep the plant within its space; it can spread vigorously.
• Cut back untidy growth after flowering and divide established clumps if needed.
