Eryngium planum 'Blauer Zwerg'

Sea Holly (Eryngium planum Blue Dwarf)

• Position: full sun
• Soil: dry, well-drained, poor to moderately fertile soil
• Rate of growth: average
• Flowering period: July to September
• Hardiness: fully hardy
  
  Easily recognised by their ruff of spiky bracts surrounding a prominent, cone-like centre of tiny flowers, sea hollies make a bold statement in a sunny border or gravel garden. This variety produces masses of small, intense blue-purple, teasel-like flowers on branched stems from July to September. It is low-growing and evergreen and therefore a great choice for the front of a sunny, well-drained border or gravel garden. The spiky flowers are also perfect for use in dried flower arrangements.
  
  
• Garden care: Lift and divide large colonies in spring. Avoid the temptation to cut back the flower-heads in autumn as they provide interest in the winter garden.
