Dannahue "Danny" Clarke is a British horticulturist who co-hosts the BBC series The Instant Gardener with Helen Skelton. Clarke was born in Oxford to immigrants from Jamaica. He changed careers from sales and founded his own garden design company in Bromley in 1997, and called himself The Black Gardener after noting that another businessman calling himself the Black Farmer was having success. The name led to him being noticed and invited to screen test for The Instant Gardener, a daytime BBC programme that started in 2015. He also appeared as a presenter for the BBC on the RHS Chelsea and RHS Tatton Flower shows and Tree of the Year for Channel 4 in 2016.
