Something I realized today, upon seeing a tiny kind of apple in the store called a lady apple, is that there is a lot more variety of species and breeds of fruits than there are of vegetables. Now before you disagree, think on it a moment: most of the things that are considered vegetables are actually fruits. Because they contain seeds.
The following are all those "veggies" that are actually fruits:
* Corn (true, it's the seeds you eat, but the husk contains the seeds)
* Bell Peppers
* Hot peppers
* Other peppers
* Mushrooms (on a technicality, as they are the part of the fungus that makes spores)
* Green beans
* Peas in the pod
The following are the REAL veggies:
* Asparagus (AFAIK)
But my point is, if you think about those things, most of the foods (of fruits and veggies) that have a lot of variety of types, species, and breeds are fruits. The veggies, not so much. Broccoli? Only one species/breed that I know of. Cauliflower and asparagus, the same. Lettuce has several varieties, but not a huge number. Cabbage has two varieties that I know of. Spinach, one (unless "baby spinach" is its own breed). Tea, if it can be considered a vegetable, has myriad varieties though. Potatoes and onions have the most variety of any vegetable (unless you count tea) that I know of. Carrots have two kinds that I know of, unless baby carrots don't count.
But tomatoes? OH MY GOD the varieties! So too olives, squash, peppers, and mushrooms among others. And fruits that are actually popularly considered fruits have astonishing levels of variety! (Methinks it may be because people tend to like fruits more than veggies.)
