He’s the 15-year-old artist known as Mini Monet. His first landscape sold for £14,000 when he was just six.
Now Kieron Williamson, from Norfolk, faces his biggest challenge… to paint at the Chelsea flower show.
The show is attended by scores of VIPs and the Queen. Kieran's not used to painting flowers but he's undaunted.
He’ll be painting in the Hillier garden - the nursery is hoping to pick up its 73rd gold medal at this year's show.
Kieron's paintings from Chelsea will be auctioned online afterwards to raise money for The Wessex Cancer Trust.
