last year I was lucky enough to receive a few seeds from the usda seed bank. these ones, Ribes lacustre didn't germinate but just in case I kept them watered and set the pots outside for the winter. There were something like 5 seeds the size of a grain of sand in each pot, some of them old like ten or more years - seeds of a specific native currant I want to grow in our collection of native plants. here one of each is growing, about fifteen months from when they started. this method should be useful for seeds with a deep dormancy, keep them in some pots in the shade watered just as long as it takes, the manual method is the dr deno system 70/40F oscillations for 3 months in and out of a fridge in a bag with damp medium. about the Ribes - I'll grow each plant as an accession - which just mean a unique plant which may have some distinct genetics, some novel trait - the usda recorded exactly where they were collected, maybe one will grow better here or be easier to propagate.
