Periwinkle

Vinca difformis

• Position: full sun to full shade
• Soil: tolerant of most soils
• Rate of growth: average, non-invasive
• Flowering period: April-June and then August- September
• Flower colour:powder blue
• Hardiness: fully hardy

  
  Not to be confused with some of the coarser forms, this selected Vinca produces pretty star-shaped flowers of pale blue on arching stems. There are two seasonal flowering peaks; the first in spring, then again in late summer, but one can enjoy a light scattering of flowers almost continuously between these peiods. The shiny, oval leaves are reliably evergreen, creating a welcome bright carpet to any shaded planting.
  

• Garden care: Trim off old outer foliage in early spring to reveal new central growth which bears the flowers.
