Petunia x hybrida 'Sparklers'

Petunia x hybrida 'Sparklers'

  • NEW in 2013
  • Fleuroselect Approved Novelty
The first ever star-shaped petunia from seed! A white version of this uniquely-shaped flower was originally sent to us by a customer in 1998. After 10 years of breeding and many generations of selection, the perfect star shape was obtained as well as this fabulous range of colours. Even the foliage of Petunia x hybrid ‘Sparklers’ is unusual, being pointed rather than rounded. Grow this striking variety in containers or let its spreading stems spill over the edges of hanging baskets for a most unusual summer display. Height: 30cm (12"). Spread: 35cm (14"). More info
