Question of the Week

I'm an urban rental dweller--West Portland--whose elderly landlords would rather deal with issues with the house rather than the yard, on which grass seed that I've bought does not grow; the soil is depleted and I can't really afford to pay for bag after bag of compost or fertilizer (it's a pretty big lot). So after a little research I read about the endangered Oregon Kinkaid's Lupine and am wondering if that could be planted here for a few years to enrich the soil and grow harvestable seeds for others to grow. I doubt the landlords nor the neighbors would object, given that the yard is mostly moss and dandelions now. Any merit to the idea?
