Award-winning gardener Alan Gardner guides a team of aspiring horticulturists with autism in this reality series. The green-fingered host, who has Asperger's syndrome, believes that the autistic spectrum disorder can sometimes give people an advanced skill in creating aesthetic spaces. Putting his theory to the test, the garden designer enlists a group of autistic trainees to work on garden projects across the UK. The group's task is to transform unkempt plots into beautiful settings. As the students create inspirational designs, Gardner shares his practical gardening tips for the home.
