Laxton's Progress #9 is what I prefer. If you broadcast the seeds rather than sow in rows they plants will support themselves. They grow about 2 to 3 ft tall so grown this way no need to trellis. When you want to pick them just wade in and pick; you'll most likely get 3 pickings, depending on how soon the heat comes on.
Note: Laxton's Improved is NOT the same as Laxton's Progress #9 so beware you don't buy the wrong variety.
Hope this helps.
