West Hampstead’s The Camden Society are selling the vegetables ahead of Halloween.
The charity aims to help people with learning disabilities live their lives free from discrimination.
They provide apprenticeships, training and employment at their social enterprises including the Mill Lane Garden Centre, where the pumpkins are being sold.
The vegetables can be purchased for £2.50, with the money going back into the charity.
The centre is open from 10am to 2pm on Saturday October 28.
Centre Manager Michael Inman said: “Come along and visit us in West Hampstead this weekend to pick up your plump pumpkins in time for Halloween.
“You’ll be helping a great cause because all profits are put back into supporting people with a learning disability to train in horticulture, build a career and plan for a great future.”
