The event will take place on Friday 11 June from 6.00pm to 8.00pm.
North One want people to "mingle with the single, grab some gardening advice and, pick up a plant, or a partner".
The centre will be giving out complimentary fizz and nibbles, a 10% discount on all purchases that evening, and expert gardening advice.
Paul Holt, shop manager, who came up with the idea because nearly all his friends were in relationships, said: "I want to make being single more fun so I mentioned this idea to an unattached friend over dinner. Seeing his enthusiasm, I knew instantly that I was onto a winner.
"All I had to do was convince the recently remarried owner Beryl Henderson about what I had planned for a summer's evening in her beloved garden centre."
He added: "It has always been a place for people from the trendy neighbourhoods of Hoxton, Shoreditch and Islington to find inspiration. Now we hope it will be somewhere they can swap tips, maybe even on companion planting, and make like-minded friends. Who knows what buds might pop?"
