Its the most expensive spice in the world & worth more than its weight in gold, but this little gem of a plant isnt as delicate as you might think. It's hardy down to -15C! This little treasure will happily live in your garden & give you a stunning display of violet & amber in the shortening autumn days, as well as a golden harvest of precious Saffron threads. Plants are despatched early August & should be planted out immediately. Harvest: October. Pluck out the red saffron threads with a pair of tweezers (yes, its worth it). Packed with naturally mood-enhancing properties to boot! Latin Name: Crocus sativus. Spice up your cooking & your garden. Savour the flavour fresh from your garden or windowsill.
