What you will receive

Tubers

You will receive the stated number of tubers, packaged in a wax envelope. We grade tubers by passing them through a grate. Small tubers are those that won’t fall through a 1/3″ grate, but that will fall through a 1 inch grate. Medium/large tubers are those that will not fall through a 1 inch grate.

Seeds

Seeds are open pollinated. Because oca is a polyploid hybrid, the seeds will not grow true to type. They are suitable for use in breeding or conservation efforts and could be used to select varieties similar to the parent type.
