Adopting a rather different image to most gardeners we see on TV, Alan Gardner has pink hair, tattoos and paints his fingernails. But he also has medals from the Chelsea Flower Show including a silver to vouch for his horticultural skills.

Helping him to makeover the gardens in the series of four programmes are five other autists who have problems with communication and social interaction. Autism will affect all of them throughout their lives with the result that they hear, feel and perceive the world in a much different way to other people.

They are all keen gardeners, in the group are Philip who is particularly interested in exotic plants, Charles grows vegetables, Victoria loves colour, Thomas craves precision, while James is a walking plant encyclopaedia.  

Alan sees mathematical formulae everywhere in the garden, visualises everything in great detail and uses patterns to create outstanding gardens. He galvanises the team, organising them to make the most of their potential. 

In the first episode an unloved garden in Derbyshire is transformed to the delight of initially sceptical owners. Lilac railway sleepers are draped in netting, an insect hotel and turf giant installed, not forgetting a vibrant planting scheme.

The next three programmes focus on London gardens which need to be transformed on schedule and to budget, making a small garden appear much larger, tackling a 95ft jungle and then, battling against adverse weather conditions. 

1.3m viewers tuned into to the first of the Channel 4 series and saw that autism which, due to flawed interaction skills makes teamwork difficult, can be channelled into gardening to create some wonderful results.
