Hi I don't grow any for particular purposes. I grow very little summer saqush , just a few bushes.After that I grow them truthfully beacause I enjoy it,The variations aee tremendous and they are beautiful. I use many for decorations in the house, a basket of assorted ones goes to a harvest festival,I share them with friends, and I eat them.I do make pumpkin pies, one a traditional one and one a cheesecake type with a ginger crust smothered in cream , so I do grow ones that rae better for pies. Most of the pumpkins are not actually. The huge big ones are not much use. There are varieties that are superb for pie. There are variations in taste , teaxture and keeping ability just as there are in potatoes and tomatoes.
Most of all I just have to grow them. If I find a new one I just have to give it a go.
