Saffron is the most worthful spice on Earth . It can sell for $ 10 to $ 20 per gramme . ( Gold was recently trade around $ 40 per gram . ) So it might not storm you that this “ cherry-red gold ” is also the most adulterate spice . And that ’s not fresh . Merchants enamour sell false Crocus sativus in Bavaria in 1444 were burned active . So if someone attempt to sell you “ saffron ” at a much better price , you might be face at safflower ( also called Mexican saffron crocus ) or even dyed corn silk . Let the buyer — and the vendor , if you ’re in Bavaria — mind .
That 1 - gram container you might see in the storage or online has stigmata ( female parts ) from 50 to 100 flowers and might be enough to flavor and discolor a large jackpot of paella or Italian rice . Despite being red , the stigmata give food a luscious yellow colouration . The name , saffron , comes from the Persian news sahafaran , that derives from asafar , which mean “ yellowed , ” according to Sustainable Agriculture , Vol . 1 .
What is saffron and what does it take to tuck this harvest ? The spiciness is the ruby-red brand of a declivity - flower crocus ( Crocus sativus ) . The stigmata are also called “ cerise threads . ”Shutterstock
When the flower with its honeylike fragrance give in October or November , hunker workers glean the entire prime in the morning and deck what they collect on a tabular array . In the afternoon , prole draw the petals away from the three stain so they can dry on an individual basis ; even the petals have a market . They ’re sold in France for cosmetic , ribbon and potpourri at $ 14 per Panthera uncia .
There is a third marketable craw . This crocus give rise no viable cum , but the mother bulbs generate two to eight girl bulbs every time of year . Those can be used to expand production or to deal to other farmers and gardeners at about 30 cents apiece .
Iran spring up 90 percent of the world ’s saffron harvest , and that might be where saffron originated . The U.S. is the world ’s biggest importer of orange yellow . It gets the spiciness from the Mediterranean , where most of the residue is produce . But the huge legal age of saffron in the U.S. is buy by the pharmaceutic industry for make believe drug that potentially armed combat impression and cancer .

When I first thought to write about growing Crocus sativus , I expected to recommend that farms on the West Coast in part with Mediterranean climate and soils would have the good luck . But research worker at the University of Vermont’sNorth American Center for Saffron Research and Developmenthave had great fate growing this bulb that ’s adapt to climates warmer and drying agent than New England ’s .
Saffron bulbs formally tolerate the stale weather of USDA Plant Hardiness zone 6 . But they outlast zone 4 in Vermont by spend their winters in the mellow hoop houses used to uprise tomato in summer . So Fannie Merritt Farmer can get two high - dollar crop from these structure . In a Vermont wicket family , farmers can gross $ 3.50 per square ft with Lycopersicon esculentum , while saffron crocus can make $ 4 per square base .
These researcher have figured out a means to give the bulbs the great drainage they like , protect them from rodents and make them portable between season . They grow them in milk crateful lined with landscape painting framework . At $ 4 apiece , the crates are the gravid startup disbursal . The researchers do n’t cite it , but I mistrust that quondam nursery potful would also work . They ’d cost nothing or next to nothing and would spare the grower the price of lining the crate with fabric and batten down the sharpness with duct tape measure . The large greenhouse pots also have handles , like the crate .
The important news is that if sodbuster can grow saffron fruitfully in Vermont , you may pretty much uprise it anywhere in the U.S.Shutterstock
Saffron’s Life Cycle
Saffron bulb come on the retail and wholesale market place in the summer . The medulla oblongata are sleeping in July and August ( the driest months in the Mediterranean and central Asia ) so that ’s when they are get the picture up and divided .
By September , shoots start . By then the retail garden shops have mark them down , and that might be a dependable way for you to get a kickoff get a line about this craw on a small scale . That ’s what I did .
In declension , the bulbs come out of quiescency and send up leaves and heyday . If you have bulbs to engraft , bury them deeply in the soil — about 5 or 6 inches — to promote florescence and division , and to protect them from mite . They care well - drained soil , morning star , potassium , a neutral - ish pH , some constituent issue and a sunny site .

If you grow them in glasshouse pots or milk crates trace with framework , put down a 4 - inch stratum of topsoil , set 11 bulbs pointy - side up , then cover with another 2 in of surface soil . Top that off with 4 inches of perennial potting medium conflate with compost . irrigate them well to get them started . Harvest blossom in the break of the day before they evanesce in the heat of midday .
Unlike common ornamental bulbs , which go sleeping in the winter , saffron crocus grow during the winter , once they finish up bloom . They still need Lord’s Day and moisture . So you must control they get irrigation when nature does n’t provide . If you ’re north of zone 6 , keep them in a high ring house or even an unheated glasshouse to protect them from too much cold-blooded .
In spring , the bulbs use their accumulated energy to grow daughter bulbs . So even if you ’ve moved them out of the glasshouse or basket sign to make room for other crop , they need water system to grow . By the strong ending of outpouring , the leaves start to die back . Once abeyant , crate can be save somewhere out of the rain for July and August .
Bulbs should be grok at least once every four year to forestall overcrowding . turn over them more frequently if you have a market for medulla , which should have a circumference of 4 inches if sold . small electric light can be used to set off new production .
Rather than pawing through the container for bulb , dump it out on a tarp . Gather and classify bulbs . Then supervene upon the soil and fresh bulb in the crate . Excess bulbs can be used in new container or clean and sell . Just be sure not to offer up any fake one .
