Helton Josue Teodoro Muniz is a rare fruit collector. He has planted and cultivated over 1,300 species in his six hectare garden in Campina do Monte Alegre, in the state of Sao Paulo, Brazil.

He was born with a motor neurone deficiency and only learnt to walk as a teenager. Today it is still difficult for him even to hold a seed.

But the childhood discovery of a fruit he had never heard of propelled him on a journey which led to the Rare Fruit Farm. 16 years later he is an internationally renowned fruit expert and author.
