A social media post from his official account said Zephaniah did not like flowers without roots but asked people to consider planting their own instead.
“We recommend that if you want to, please plant something like flowers or trees anywhere you wish and name them as Benjamin Zephaniah in memory of him,” the post read.
People were told they could also donate to the Vegan Society if they wished.
On top of his writing work, Zephaniah was an actor and appeared in the BBC drama series Peaky Blinders between 2013 and 2022.
He famously rejected an OBE in 2003 due to the association of such an honour with the British Empire and its history of slavery.
