Daikon radish is a much larger, longer-rooted relative of the standard salad radish already covered on this site, different enough in growing needs to warrant its own profile rather than a variety note tacked onto the smaller root.
How daikon radish fits zone 11's season
Zone 11b is frost-free in this dataset, so frost is not what limits the calendar here. What you can plant, and when, comes down to summer heat and daylength instead.
