Does anyone know what this is? I grew it on the allotment from a packet of seeds someone gave me. The packet had a picture on the front and the times for sowing etc, but the top was ripped off so I didn't have the name.
The plant was large and sprawling rather like a butternut squash or pumpkin. The "fruit" is about 9" in diameter. I don't even know if it's ripe or if it would get bigger if I left it on the plant. I cut two of them today, and there are several more still on the plant.
The flesh has a pleasant mild taste, somewhat like a marrow but sweeter.
