What you hope dat your crop-yield will do, but never really count on it.
Usually da Gurney's, Burpee's, and Park's catalogs really hype and puff da growing/harvest-claims of da little dried things inside their proffered planting-packets, so you should not exactly expect an actual "bumper crop" on much of anything dat you order from them --- about da only germination and flourishing dat will likely exseed your expectations will be all of those blasted WEEDS dat you're constantly having to dig or pull out! :P
