tug, I am wondering if the blackening is simply what happens when it gets colder, or if it gets sooty mould...

Lol! I shall follow the pics with interest. It's not true black cumin, that has white flowers, and the Nigella sativa (black cumin, black caraway, black clove are common names, not really cumin at all) has white or blue flowers.
