This is an heirloom variety originally from Cusco, Peru. Collected by Ben Kamm of Sacred Succulents; variety names that begin with BK are his collection numbers.
Initially, I wasn’t very impressed by this variety. For the first few years that we grew it, it didn’t produce very well. Then it started to get better and turned out really good performances in 2016 and 2017. The tubers are yellow with red eyes and mostly in the two to four inch range. The eyes are a little bit scale like and the tubers are somewhat flattened, which makes this variety easy to distinguish from the many other yellow and red varieties. I’d still call this one an intermediate yielder, but some of the tubers are very long. The flavor is pretty mild with no detectable acidity after exposure to sunlight. Typically a shy flowerer with a short styled flower morph.
What you will receive:
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 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.
