The story
Saffron was grown on Crete 3,500 years ago and painted on Minoan frescoes; Kashmir has grown it since at least 500 BC, and Persian cooks built a cuisine on it. Each flower gives three threads, picked by hand at dawn, which is why it costs what it does.
Planting
Full sun and sharp drainage; wet summers rot the corms. Plant corms 4 inches deep in late summer; they flower in autumn, grow leaves through winter, and sleep in summer.
Growing
Water only when the leaves are up, in autumn and winter; keep dry in summer. Lift and divide every three or four years as the corms multiply.
Harvest and use
Pick the flowers the morning they open in autumn, pull out the three red stigmas, and dry them on paper for a few days. A hundred flowers make a gram.
What to watch for
Rot in wet soil, and rodents, which dig the corms.
