Jersey Knight is an good choice for your area; however Jersey Giant would be a bit better for your hardiness zone. Starting from seed is a much longer process then buying asparagus crowns, http://www.gardenharvestsupply.com/P...Crowns-c48.htm You will lose at least an additional year over the normal 1/2 year wait on new asparagus plants; however if you are still eating off of told bed it should be no problem. Think Spring!
