A type of nitrogen fixing corn that is native to Mexico that might be big thing in the coming years.

This is something I just came across this morning, not exactly what you were looking for, but it's pretty interesting anyways.

It's a nitrogen fixing corn from Mexico:

Siberian Pea Shrub is the first thing that comes to mind for me. It seems to meet most of your requirements though I don't know how it does in drought situations.

About 5 years ago I planted two kiwi vines.  I bought and planted one labeled FEMALE and one labeled MALE. 
As luck would have it, they finally both bloomed this year, and both are  clearly FEMALE.

How do nurseries even know if a vine/tree is one gender or the other before they have obvious sex characteristics like flowers?

I've bought a third kiwi vine, supposedly male, but I hate to plant it just to find out in 4-5 years that it is also female.

Good luck with the kumquat.  My personal opinion is that kumquat is one of the best choices for cold hardy citrus.
Mine took a beating last winter, might have to dig them back up and repot, grow indoors for another year or two
so that they will have more adult resistance to cold.

Make sure you have things that eat mosquito larvae.  Frogs and fish think they are yummy.  Dragon flies. Birds.  A healthy eco-system in your pond will attract mosquito predators.

Often people pull the whole "rip up the whole patch and replant" when they keep the strawberries in a contained, linear row under plastic that prevents runners from creating new plants. If you let strawberries do their thing, they'll keep going indefinitely.

That's pretty much what I was guessing.  Putting strawberry plants in an artificial situation results in the necessity for replacement. 
Letting them grow like they do in nature, should result in self-replacing plants.

The plants I have are mystery plants.  They came from the edge of the woods of my property.  They definitely spread by stolons.
I started with about five plants a few years ago, now I have hundreds. 

Thanks for that response Miles.

I spent a good hour searching Google and everything I read says that you essentially have to start over every so many years.
Just watching how they grow and spread themselves and procreate that seems questionable to me. 

Maybe that's just some "garden wisdom" that is just handed down generation after generation without question? 

I've looked around the web but I can't seem to find an answer to a question about strawberries:

Every where I look it says that strawberry plants have a lifespan of 3-5 years, then they stop producing berries, die off.

Everything I read says that basically you have to rip out the whole patch and start all over, but that doesn't make sense to me.
Wouldn't the younger plants produced by the stolons of the original plants take over for the ones that die off?

Shouldn't a patch be more or less permanent,  Just replacing itself little by little each year? Or is there some built in genetic
limit that kills off the whole patch, older and younger plants all at once?
