  A vigorous, low-creeping plant that forms a carpet of pretty snowflake-like flowers during the summer months above mounds of green foliage. Easy to grow in a sunny, reasonably well drained position, and ideal for walls and rockeries. Looks amazing tumbling over walls, pots, and rocks. ‘Alba’ is drought tolerant once established.
  
  
• Garden care: Cut back hard after flowering to maintain a compact habit. Lift and divide congested clumps in autumn or spring.
