The most promising method to obtain day-length neutral strains of Oca is to look for the trait in the variable plants grown from true seed rather than clones grown from tubers.
Seed can be obtained if you can persuade more than one variety of Oca to flower simultaneously, but that is more easily said than done as Oca may, or may not oblige in that department depending on unknown mystery factors.
One gardener in one location cannot see the factors, or at least not this gardener. Observations on flowering periods are needed from a wide geographical and climatic range - then hopefully a pattern will be evident when viewed overall.
Do your bit for the Oca breeding effort, push back the frontiers of the Oca-unknown - join the Radix Root Crops facebook group, and contribute to the discussion 'Flowering Ocas: Where and When'.
Even knowing that Oca is not flowering in a certain location is useful information.
If you're not into facebook, leave a comment here about your flowering (or non-flowering) Oca. Dates, location, recent weather... anything that you think might be relevant.
Come on Oca flowers out there - show yourself!
The tiny flower buds grow from leaf axils near the growing tips of stems.
