Angelica

Angelica gigas

• Position: full or partial shade
• Soil: deep, moist, fertile, loamy soil
• Rate of growth: average
• Flowering period: August and September
• Hardiness: fully hardy
  
  A stunning, architectural plant that adds height and drama to a border.  Dome-shaped heads of plum-purple flowers appear on red-tinted stems in August and September and it has pretty, deeply cut leaves. Try it at the back of a sunny, herbaceous or mixed border, where the flowerheads will attract bees. It performs best in moist, fertile soil. This plant is monocarpic, so dies back after setting seed.
  
  
• Garden care:  To prevent the plant from self-seeding, deadhead after flowering. Even if you leave the seedheads, it tends not to self seed as freely as other angelicas, so needs to be replaced regularly.
