Nice series, enjoyable to watch, provides an opportunity for the autistic adults to develop and contribute. I would welcome them in my garden any day. All the gardens so far have an element of wacky colour: I think it could be a trademark of the designer. Alan Gardener looks a bit cross and world weary sometimes, as if life hasn't been kind to him. He seems such a nice person though and must have great initiative to have got this far with his condition. I hope life is kinder to him in the future.
