Thompson & Morgan have done it again!  They have launched their latest world exclusive plant breeding success.  Sunbelievable is a truly phenomenal new sunflower.  Like no other sunflower, Sunbelievable flowers continuously from June until the first frosts.  In trials, plants were still blooming in late November.  Incredibly, over 1000 flowers are produced on each plant during the growing season.

Features of Sunbelievable include:

  • Very floriferous and free flowering
  • Stunning bicolour blooms
  • Multi-branching
  • 1000 flowers over the growing season
  • Fabulous cut flower
  • Hugely decorative patio plant
  • Truly compact – Height: 60cm (24in) Spread: 100cm (39in)
  • Day length neutral – blooms even on shorter, less bright days
  • Sterile – so no pollen but still very attractive to bees
  • Heat tolerant – great for hot, sunny borders
  • Thrives in any well-drained soil
  • Will recover quickly if left to dry out
  • Deadheading improves flowering performance

Paul Masters, Thompson & Morgans’s Head of Horticulture, said:

“Sunbelievable is an amazing breakthrough in decorative plants for the garden in an area that has been distinctly lacking in innovation in previous years.  We expect this fabulous new sunflower to make a real impact in people’s gardens – it’s non-stop blooming will appeal to sunflower lovers and gardeners everywhere.”


Set to create quite a media buzz, Sunbelievable is the product of eight years of work by Thompson & Morgan’s breeding team.  Head plant breeder, Charles Valin’s vision was to breed a sunflower that was long-flowered and which could be used and enjoyed as a bedding plant as well as in containers.

Charles comments:

“I was always disappointed by the garden performance of traditional pot sunflowers.  I’ve crossed the very best with the very best to really boost the plant’s performance.  I still can’t believe how many flowers this plant can produce!  I also realised that it was the energy that the plant put into setting seed that was preventing it from flowering for long.  So I aimed to create a new hybrid that would not set seed and would therefore carry on flowering all summer long.”

Sunbelievable is available exclusively from Thompson & Morgan’s website for delivery from April 2018. £14.99 for a 9cm potted plant or £19.99 for two 9cm potted plants (saving £9.99).  To view the products click here and be one of the first to enjoy this amazing new breeding.
