A Rhododendron flower exhibitThe Horticultural Competitions run by the RHS are open to all (you don’t have to be an RHS member) and free to enter.

They cover a wide range of ornamental plants as well as fruit and vegetables; a variety of prestigious trophies and prize money are awarded to winning entries.

Competitions are held in gardens and at RHS Shows across the country:

  • RHS Garden Rosemoor in Devon

  • RHS Garden Harlow Carr in Yorkshire

  • RHS Garden Wisley in Surrey

  • The Savill Garden, Windsor Great Park

  • RHS Flower Show Tatton Park

  • RHS Horticultural Halls in London

New competitors are welcome and our friendly stewards are always ready to help, so if you have a lovely Camellia or Rhododendron growing in your garden but know nothing about it, cut a branch and bring it along to the show during staging, and we will be happy to help you identify it and enter it in the competition if you wish.

If you have any queries or would like a copy of the schedule emailed to you please contact the Horticultural Competitions Manager: Georgina Barter on 020 7821 3142 or email to Georgina Barter.
