This frankly unremarkable picture of some frankly ordinary oca seeds hides a portentous event. For me, that is. These are the seeds I've just collected from the self-sown oca seedlings that sprang up unannounced and, if truth be told, inconveniently among the rocotos. It is, therefore, theoretically possible to produce an annual supply of oca seeds outdoors in our indifferent summer weather, without recourse to any elaborate horticultural facilities. Reaping what you sow, all within a single season - that's surely progress. I am preparing myself for the inevitable media onslaught that will ensue from this paradigm-shifting, epochal moment in the ongoing acclimatisation of oca. Don't all rush - let me comb my hair and clean my fingernails first.
