A grapefruit tree, to be exact. Planting trees in this part of Texas consists large of geology, as, once you get past the top soil, you're removing at least 15% limestone by volume. At this point in toilage, the shovel is no longer a functional tool, as even the smallest rock will stop it. Instead, one digs with a pick axe. :)

This is a cold-tolerant (to about 15 or 20 degrees) variety with a full-sized rootstock. I got five orange-sized grapefruits out of it last season (like, just now) when it was still living in a 15-gallon pot, so I'm excited to see how it will do with more room to stretch it's insubstantial, sponge-like roots.

I hope it hurries up, because after digging out rocks for 5 hours, I'm pretty hungry.
