Hillingdon in Bloom

A free competition that encourages local gardeners to improve their environment through the imaginative use of flowers, trees, shrubs and landscaping.


In recent years the popularity of Hillingdon in Bloom has grown considerably, with amateur gardeners from all parts of the borough taking part throughout the summer months. From large front gardens to the smallest of window boxes, residents or businesses in the borough can take part.


  • Best first time entrant.
  • Best window box - boxes must be on, or attached to, the house window sill and not a free standing container.
  • Best hanging basket.
  • Best balcony - best display on an open fronted balcony.
  • Best bloomin' business.
  • Best school project/display - planted out and showing evidence of being cared for by the children.
  • Greening Grey Britain for wildlife. 
  • Best Community Project (Residential Street) - group entry to include a minimum of four adjacent properties working together to create an overall garden display. We will ask for the contact details of the group.
  • Best display (includes novelty display) - for an exhibit within a garden that incorporates temporary planting and/or garden ornaments and structures.
  • Roome Cup - awarded to the garden that is judged to be making the greatest contribution to wildlife conservation.
  • Best residential garden - this can include a rear garden only if it is clearly visible to the passing public.

New for this year -  Greening Grey Britain for Wildlife. Taking inspiration from the Royal Horticultural Society initiative of the same name, residents are encouraged to come together to tackle grey corners of the borough and give them a new lease of life with plants. Of course you'll have to ensure you have the land owners permission.

Britain in Bloom

As part of of Britain in Bloom there will be a new initiative that Hillingdon will take part in for the next three years called Greener Streets: Better lives, in an effort to 'green up' our grey spaces, such as streets and high streets.

Greener Streets is a Royal Horticultural Society Britain in Bloom initiative. By adding plants, we aim to transform these often dull and uninspiring areas to beautiful green spaces and improve the quality of lives of residents, business owners and visitors.

Our Green Spaces team will be happy to help with any gardening advice you may need, including your green streets ideas. Please email contact@hillingdon.gov.uk or call 01895556000. 

The council will also be providing, on application, financial grants of up to £1,000 for gardening materials to help residents and community groups to take part in the Green Streets initiative.
