Cucurbita pepo F

for competition purposes, the following distinctions are made between marrows and zucchini (syn. courgette): A marrow is grown on a vining plant, a zucchini on a bush type plant without vines. A marrow generally has rough skin while a zucchini generally has smooth skin. A marrow is generally quite uniform in thickness while a zucchini tends to taper out towards the blossom end.

Specific rules:

a. The vine must be trimmed within 2.5 centimetres (1 inch) of the stem.

b. Marrows may be green with green or yellow striping or completely yellowish-white. No orange colouring is accepted.
