We are trying Dave 407 from Adaptive Seeds and Red Head from Uprising.
I have planted a flat of 72 cells for transplanting to the Fall City garden.
Here's what adaptive says:
A good feature of Red Head is that the seeds are less likely to sprout on the seed head just before harvesting. This happens in moist conditions. The loose arrangement of the seed heads allows the seeds to dry out after rain.
I intend to plant Red Head quinoa directly into the Fall City farm.
The following description is from Uprising Organics.
It is pretty unfussy and a visually beautiful plant in bloom. A close relative to the common weed, lambquarters, we actually recommend transplanting quinoa so you can know with certainty where it is in the field as it is virtually indistinguishable from its weedy cousin in the early vegetative stage.
Red Head is a selection by Frank Morten out of some of the first wave of imported quinoa to withstand potentially wet and cool fall harvest times, something it doesn’t often face in the Andes. It has a more open head structure and resistance to premature seed sprouting in wet weather near harvest time.
