McQueen chose the rose personally to pay tribute to his friend and mentor Isabella Blow, former editor of Tatler magazine and an international style icon, who died in 2007.
Following McQueen's death in February this year, the rose will be used to honour both the designer and his mentor when it is unveiled to the public.
Breeder Colin Dickson said: "This is the one Alexander McQueen chose himself after looking at hundreds of pictures and he had been due to come to the show to see it launched."
Dickson said the process had begun about 3 years ago when McQueen's office proposed the idea of naming a rose after Isabella.
Familiar with the designers work and with a family of McQueen fans, Dickson said he was happy to oblige.
He explained: "My wife was an admirer of him and my daughter who is 12 said she wanted to be a model and was hoping he would be able to point her in the right direction."
The rose itself is a has coral peach blooms, borne singly or in clusters, offset by dark green, semi glossy foliage.
A floribunda variety, it has an upright to bushy habit and a slight fragrance, described by the breeder as "a very robust grower."
It has good disease resistance and reaches heights of about 80cm.
McQueen is said to have chosen it as it reflects Blow's colourful personality, celebrating her love of fashion and opulent dressing.
It is being sold through C&K but Dickson said it was available to anyone who wants to grow it.
The company will also be introducing R. ‘Maid of honour' at the show. It is being marketed as a "shrublet" with pale pink, very prolific flowers, ideal for container growing. It will also be shown by C&K.
