Sun requirement for triamble pumpkin: Plant in Full Sun

The three-lobed pumpkin of past decades. Seed came from Margaret Hulme of Gisborne, who farmed for 45 years on a post-war rehabilitation farm at Young Nick's Head; it was a local Māori gardener's special pumpkin, and his family returned the seed to her after he died. Solid orange, tasty, good for everything and a good keeper.
