I grew Saffron Crocus (Crocus sativus) at my other house and managed one meal from the collected stigma (the culinary term is thread) of the several bulbs that I planted. I blogged about it here and here. The scent was incredible, but I think that I didn't manage the saffron threads very well because the cooked flavor was faint. Or perhaps I didn't have enough. C. sativus is a mediterranean plant, so it's compatible with low water gardens and a prime choice for those that want to grow an exotic and expensive seasoning.
Besides kitchen uses, saffron has been used in folk medicine for centuries and more recently leaves and threads have been evaluated as anti-depressant and anti-inflammatory agents, with findings that the threads are pharmacologically active.
In late October of this year I planted 70 Crocus sativus bulbs. To spare you many pictures of freshly planted bulbs, I'll let you search Google for pictures of soil instead.
Fast forward to mid November, and we have action!
The bulbs are poking their first leaves out of the planters in several areas. At Juli's house, where I planted a few days earlier, the signs of growth were slightly earlier, just as one would expect.
