I don't have any specific ones on a must-have list. I'm aiming to have self-sustaining pasture that still looks nice (because my husband wants it to be pretty)...if I can get some deep-rooted perennial wheat, oats, rye, clover, etc, we can use a mowing schedule along with rotation to capture
water and fertility...we're in what's called "xeric sand hills" so nothing sticks around for long. I'd rather avoid amaranth because it gets weedy quick in our climate.
I feel like if we can get some
deep roots going
underground, we'll be able to start building up above-ground.
