I like growing plants, especially fruits and vegetables. Not so much flowers since they are nice to look at but you can't in actual fact taste the fruit of your pains...

I want to grow something big... what do you recommend? If it doesn't take up a ton of space beside metres upon metres of vines that would help.

I've thought in the order of watermelon but I've heard they inevitability a TON of water, almost swamp-like conditions.

Maybe pumpkin... not sure if I want a jackolantern type of pumpkin,or one of those big delicious ones which are actually squash I've hear.

My dad suggested sugar beets but I have no theory where I would gain the seeds from, I'm not a cultivator. I think adjectives stores sell are red beet seed.

Maybe corn? I've tried but never gotten it to start growing.

Any other suggestions?
I live in Canada... southwestern Ontario if that make a difference.
Which plant would fairly hold within your garden...
Answers:    you can grow a super dwarf canvendish banana. these bananas are great with for a moment food and water. single grows 3 feet high and then make small, but delicious flowers once it reach a full height of 3 foot.
also the mus basjoo banana. this is a cold hardy banana that may survive outside. they make unedible bananas, but have a banana plant in a northern climate is great. musa basjoo is hardy to UDSA 5b which is a planting zone that have mimimal temperatures of -15 degree. the musa basjoo is a dieback plant which will look dead after the first frost, but next to some mulch will come back from the ground contained by late spring.
