Answer 1

Marrow - The Marrow (Cucurbia Pepo ovifera) is an annual trailing plant of the gourd family grown for its fruits which are eaten as a vegetable. Gourd (Cucurbita) is a genus of plants of the family Cucurbitaceae. The genus includes edible species such as the marrow, pumpkin, water melon and squashes. Gourds are from the same family as squashes.

Answer 2

Looks like a large globe squash, but I would say it is definitely a summer squash, regardless of the variety.  Squash can get very large if the growing conditions are good (lots of sun and water).

Answer 3
