Plantscape has signed deals to supply just over 400 of the elevated planters to brighten the north-west Leicestershire town's streets, main roads and roundabouts as part of the 2016 Loughborough In Bloom campaign.
One order, for 207 hanging baskets as well as eight window box troughs, has been placed by green space management company Quadron Services, which maintains the town's open spaces on behalf of Charnwood Borough Council.
A further 200 of the planters, along with 25 window troughs, have been ordered by the Loughborough Business Improvement District organisation Love Loughborough and will be situated in the town centre itself.
Loughborough picked up the Best Small City crown in the East Midlands in Bloom Awards last year and the planters will help the town's efforts to win a title in the national Britain in Bloom awards.
They will also help Loughborough to commemorate Queen Elizabeth's 90th Birthday year. Three-quarters of them will be planted with red, white and blue flowers, providing a patriotic backdrop to a series of birthday events taking place in June.
The flowers will be planted up in Plantscape's nursery in Ashbourne, Derbyshire, in April and the display will be installed in June.
Nicola Clarke, horticultural development manager for Quadron Services, said: "We are delighted to be working in partnership with Plantscape to create and maintain a patriotic red, white and blue display for residents and visitors to Loughborough to enjoy this year.
"Plantscape has earned an enviable reputation within the industry thanks to the quality of its displays, while there are further environmental benefits to be gained from the fact that its planters are fully recyclable and the displays are planted at its own greenhouses."
Mark Stone, managing director of Plantscape, said: "We had an extremely busy 2015 and so we are extremely pleased to have enjoyed a flying start to 2016 with two such significant orders.
"Loughborough, which is a new location for us, is rightly proud of its record in the East Midlands in Bloom awards and is going all out to retain its title this year. We are extremely proud that ourdisplays have been chosen as part of Loughborough's Britain In Bloom entry and we look forward to creating a display fit for the Queen later this year."
David Pagett-Wright, chair of Love Loughborough BID, said: "The town centre businesses really value the floral displays as part of the town's Bloom efforts.
"We are pleased to be working with Plantscape and to have been able to increase the number of baskets and troughs we fund this year."
Plantscape supplies hundreds of displays every year in a wide range of colours and last year installed a red, white and blue display on the waterfront in Liverpool for the historic visit of Cunard's Three Queen cruise ships.
It also installed an eye-catching pastel display in West Bridgford, Nottingham, including outside Trent Bridge cricket ground, to brighten up the area for crowds attending the England versus Australia Test last summer.
