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.

• Asparagus is a hardy perennial
• The key to good production is well-prepared, deeply dug beds with lots of organic matter

Great Growth but Lots of Females

These arrived in beautiful shape and they have grown fantastically in our garden bed. Downside is that almost 1/2 of my order are female plants. I was expecting to only have 1 or 2 plants out of 25 but instead have 10 female plants.
