What plants do you want to see giant-ized?
Is there any plant, vegetable, flower, et cetera, that doesn't have a large variety, but you wish it did?
Shouldn't it be genetically possible for anything to grow as large as possible, as long as the roots and leaves can provide the nutrients? (I mean in future generations of plants, not taking any variety off-the-shelf right now.)
Is growing over-sized things an American fascination, or are others similarly obsessed?
