The move follows a change in the champagne company's management which led to the decision to pull out.
Crocus has supplied and built 12 gold medal winning gardens for the company, winning best in show five times, with designers including Pearson, Jinny Blom, Tom Stuart-Smith (best in show 2003, 2006, 2008), Arne Maynard, Ulf Nordjfell and Luciano Giubbelei, who won best in show in 2014.
Crocus will be working with Andy Sturgeon on a Californian-inspired garden for the Daily Telegraph at Chelsea 2016.
The design is characteristic of the 2010 best in show winner Sturgeon's work (also with The Telegraph). Sturgeon won six Chelsea golds between 2005-12 and a silver gilt in 2001.
Sturgeon will be up against M&G designer Cleve West, whose Chelsea record is two best in shows and five golds in all, as well as a silver gilt. He won gold with M&G in 2014, gold and best in show with Brewin Dolphin in 2012, gold and best in show with The Telegraph in 2011, gold with Bupa in 2008 and gold with Saga in 2006, as well as silver gilt with Merrill Lynch in 2001.
The Dan Pearson Chatsworth garden currently has elements being returned to Chatsworth.
Jo Thompson, Ann Marie Powell and at least one other femaie designer are set to design for Chelsea in 2016. Hugo Bugg (RBC), Rich Brothers (Cloudy Bay), James Basson (L'Occitane) are among those to be announced next week.
