Asparagus officinalis: This Mediterranean native is one of the first vegetables harvested in the spring. Asparagus is among the foods identified as having the highest levels of Glutathion (GSH), a potent anticarcinogen/antioxidant, that defends against cancer. Asparagus is easy to start from seed, but you'll get an earlier harvest from our 1 year old crowns.
