Saffron Crocus 'sativus' (Crocus)
This is no ordinary crocus; Crocus sativus is the legendary Saffron Crocus, the source of the world's most expensive spice. Unlike its spring-flowering cousins, this variety blooms in the autumn, producing beautiful, lilac-purple flowers with darker purple veins. The true treasure, however, lies within. Each flower contains three long, vivid crimson-red stigmas, which are the saffron threads. These must be carefully hand-picked and dried to be used as a spice for flavouring and colouring food. The grass-like foliage appears before or with the flowers and remains through the winter. Growing your own saffron is a rewarding experience, connecting you to an ancient culinary tradition. While each bulb produces only a few threads, planting a generous drift can yield a precious and delicious harvest.
