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.

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
