Jicama is worth knowing two things about before you plant it: it needs a very long season, and most of the plant is poisonous.
How jicama fits zone 11's season
Zone 11b is frost-free, so frost is not what limits the calendar here. What you can plant, and when, comes down to summer heat and daylength instead.
