Solarium has been awarded a contract to grow more than 1,000,000 solarium patties.
The company says the plants are “a way of helping the homeless by feeding the planet”.
Solarium, which has also built solarium-patties for the NHS, says the potatoes are “the perfect supplement to help the world’s poorest people”.
The company is also developing a solarium tea.
The firm has spent £1m ($1.3m) on solarium in the past three years.
Solarium also wants to sell potato plants to hospitals.
The plant, which was first unveiled at the Paris International Food Fair in April, will be installed in a park near St. John’s Cathedral in the heart of London.
Solarisia said it had built the plants to help “people in the developing world, who have few other options”.
“They are a way of feeding the world,” said Solarium CEO Christian Rupp.
“They’re also a great way to give back to the community in a way that’s very sustainable, which we believe is a great gift to the planet.”
Mr Rupp said the solarium plants would be planted in the St. Paul’s Cathedral garden, which is “very special” and has “an iconic status”.
“There are a lot of things you don’t see in St Paul’s Garden,” he said.
“It has this very special place in the centre of London, where the people of St. James are sitting around this beautiful green garden and you see all these plants growing and it just seems really appropriate to do that.”
Mr Pazdzisz said the plant was a “great idea”.
“I think it is a good way of giving back to society,” he added.
“I don’t think people should have to go into the street and go to a supermarket, or go to homeless shelters, and there’s a good chance you can just pick up some of the potato pattys that are there.”
The project has been “taken very seriously by the government and the Department for Communities and Local Government”, Mr Pazziksz said.
Mr Pzazdzinskiz said he was “thrilled” with the success of the solarisia scheme, which he said had helped about 300 people with “unable to afford food”.
“People have been able to put food on their tables, get a cup of tea and take part in this project,” he told BBC Radio 4’s Today programme.
“And I’m really proud of this project because we have had a lot more success than we ever would have expected in such a short space of time.”
