Part of the North Park opens to ticket holders of the Open East Festival on 27 July, exactly one year since the Opening Ceremony of London 2012.
Free access to the public starts on 29 July.
The Hampshire based company supplied flowering turf for the new park, the site as it was during the 2012 Olympics and even Danny Boyle’s Green and Pleasant Land Opening Ceremony set watched by an international audience of one billion.
Managing director James Hewetson-Brown said: "We have grown two types of bespoke wildflower turf for the park as part of the reinstatement works. Some of the bespoke turf has been used in areas where the ability to cut down on maintenance and introduce native species was important.
"In addition other post games zones are being grown to supplement existing areas in and around the site including a shade tolerant mix for the Athletes Village area and some bespoke grown bioswale turf."
"More than 25,000m of Wildflower Turf’s bespoke native wildflower turf was supplied throughout the Athletes’ Village and the various Olympic sites. Mixes included shade-tolerant and woodland wildflower turf, marshy meadow wetland turf and species-rich lawn turf.
Hewetson-Brown added: "The planning application for the park was only granted on the basis that we could deliver an area of biodiverse habit as defined by the UK’s Biodiversity Action Plan, so the type and range of species in the mix was carefully selected to achieve this."Frosts Landscapes estimator Adrian Meeker said the contractor had been satisfied Wildflower Turf could deliver the biodiversity requirements of the design but this was not the only consideration.
He said: "With concerts and events going on at the park from day one, it was important that the area looked great straightaway so we needed to work with a supplier we were confident could deliver this with no problems.
"We chose Wildflower Turf based on their extensive experience, background, knowledge and understanding of wildflower turf products, and the fact that we’d worked with them before with good results."
