Description How to Grow More Info Delivery Reviews
  • The thistle that thinks it’s a sunflower!
  • Unusual border flower
  • Excellent dried cut flower

Nicknamed the 'purple sunflower', this shining beauty makes a fantastic border plant, producing a neat, ground-hugging rosette of thistle-like foliage and a striking flower stem that demands attention in any planting display. The gently prickled leaves make it a good plant to discourage pets and other unwanted visitors away from your prized borders!

Like many other South African species, Berkheya plants are very undemanding, simply requiring a sunny spot on free draining soil. Multiple flowers appear in late summer in a silvery shade of soft violet, creating a real wow factor. The stems make unusual fresh or dried cutflowers. Best planted under a south-facing wall and given some winter frost protection in colder parts of the UK. Height: 75cm (30"). Spread: 50cm (20").
