Visiting plants only once a week or so calls for very different traits than a backyard garden does. Drought tolerance, deep roots and a bushy but sturdy structure count for more than top shelf flavour in that situation.

Even tough strains struggle without some water in a heatwave, so low maintenance never really means no maintenance.
