It takes 165 crocus flowers to make just one gram of saffron spice. Saffron is the stigma, or female flower part of the saffron crocus, Crocus sativus. The large numbers of flowers needed plus the high labor costs of carefully picking just that part from the flower make it the most expensive spice in the world. Saffron is currently selling for between $4.00 and $17.00 per gram, depending on quality, with the world’s finest saffron generally coming from the La Mancha area of Spain. But you can grow your own!

Today I’m talking with Ian Hemphill about how to grow your own saffron successfully in the home garden, and then you’ll never be caught out with fake saffron which is still sold in many places.

Iran is the world’s biggest grower of saffron, followed by Kashmir and Spain but it’s also grown in Italy and Greece. These countries all have a Mediterranean climate with hot,dry summers and cool to cold wet winters. Saffron has been known and used for thousands of years, both in food and as a fabric dye and has long been associated with the wealthiest classes. The word saffron comes from the Arabic word for yellow.

Growing saffron
You need a cool Mediterranean climate to grow saffron (Zones 6, 7 and 8, and drier Zone 9). In Australia, that’s Tasmania, western Victoria, elevated parts of South Australia and areas of western NSW. You’re not likely to be successful in areas of high summer humidity or rainfall, like most of the Australian east coast. Saffron crocus is grown commercially in Tasmania, but its output is only a blip on the world’s commercial market of true saffron.
Saffron bulbs
Buying and planting
Saffron corms will be available to buy during their dormant period in summer (June to September in the northern hemisphere, and December to April in the southern hemisphere). Plant the bulbs about 5cm (2 inches) deep, preferably in full sun (or somewhere that will be sunny during the autumn/fall flowering period) and make sure the soil drains well. In warmer and temperate climates you need to put buckets of ice on the bulbs every night during winter to give them sufficient winter chilling. That seems an awful lot of effort!
Don’t over water them or they will succumb to fungal diseases. They’re very drought hardy and will probably only need watering once or twice during their growing season.
Saffron produces flowers in autumn/fall with a beautiful light purple flower, which lasts a few weeks. The leaves only appear after flowering. The corms will gradually multiply so you can lift and divide them after about 5 years to increase your crop.
When the flowers are fully opened, you can carefully remove the stigmas from the flowers using tweezers, or harvest the whole flower if you have a bigger crop. Harvesting the flowers is real back-breaking work as the plants are very small. Then there’s the delicate operation to remove the 3 dark red stigmas from each flower – the flower is then discarded as it has no commercial value.
Dry the stigmas in a dehydrator or on a fine mesh rack in a cool oven (50-60 degrees C) for about 15 minutes. Store saffron in an air-tight container in a dark place. However you will need a couple of hundred plants to get your 1 gram of saffron threads!
How to use saffron in cooking
Saffron has a very distinct almost woody flavour, and is a real appetite stimulant but you have to be careful not to use too much or you can create a bitter taste. 12-20 good quality ‘threads’ (stigmas) are quite enough for one cup of rice.

Infuse the saffron in tepid water for 10-15 minutes before you use it to bring out the colour and flavour and then tip the stigmas and the coloured water into your dish. This is the moment when you might discover you’ve got fake saffron if the colour diffuses instantly rather than taking 10 minutes or more, and is very red rather than a golden yellow. The fake threads will also disintegrate when you handle them, unlike the more robust real saffron. If you have a great recipe using saffron, write in and tell us about it.
Oh to be able to grow this beautiful and delicious plant and not buy rubbish and fakery! Sadly, my ‘cool’ subtropical climate would never agree with it. Better get Jennifer Stackhouse on the case in her new Tassie home….
Hello everyone
I am from Azerbaijan and it has been a long time since we are exporting saffron to different countries, except Australia. Recently i have learned that Australia is one of the countries which imports saffron from different countries. For this reason i would like to import our saffron to this country as well. But I am a little bit confused, cause do not know who to contact with regarding this issue.
Hi Aygun – you can find out all about importing foodstuffs into Australia here http://www.agriculture.gov.au/import/online-services/bicon
Hello Aygun,
I may be able to help you. Please email me anytime at bemalen@outlook for more information. Thankyou, Jason.
I live in Geraldton, Western Australia. Based on the climate here, is it even worth my while to try growing saffron?
Catherine, I’ve been growing saffron for a decade, with a little success. Finding the right spot can be a difficult. Bulb size is also important – small bulbs won’t flower.
On drying saffron, recent research out of Tasmania indicates that the flavour, aroma and colour components are maximised at temperatures around 80 – 85 C. The high heat modifies some of the inactive substances into active ones, This research recommends wet heat at around 85C for 20 minutes or so, followed by a short burst of dry heat. A tray of water in the oven can provide the steam necessary. Remove it for final drying.
This research is a bit hard to access – a PhD was funded by Tas Saffron I think, so the reporting is a bit vague.
So the bulbs are planted in Autumn and then take 12 months to flower in the following Autumn, or flower during the planting Autumn?
Bruce,
Flower initiation takes place the season before flowers actually emerge – it depends on the growing season whether this occurs or not. If your purchased bulbs were grown well and accumulated sufficient energy reserves to initiate flower formation in the season before you purchased them, they will flower the first season you plant them, otherwise they need to get a good growing season under their belts to flower in the following year.
The best planting times for Saffron Crocus is Late Summer to early Autumn. in general, but for WA, I would pick Autumn.
regards
Marianne
Hi,
I just found this post and interested in planting Saffron but I cannot locate a seller anywhere in WA. Would you know where to get them pls?
Thank you.
Hi Denise, I live in the lower blue mountains west of Sydney , so unlike we don’t get the high humidity, average summer temp 20-30 and winter 7-17degrees C. We also have good free draining soil. Are these conditions suitable to grow saffron? gregg
Hi we got given a gift of saffron seeds (not bulbs). Is there a difference in how to plant them vs planting bulbs?
Thanks!
I am in Sydney and grew saffron for many years ( 1917 1918 1919 )
did not get a flowers in 1919 ( a hot year April )
this year the crop grew and looks good
temperature in the soil now is 18’C in the soil , air is mid 25’C)
I am thinking of putting shade cloth over the crop to make it cooler
The people in NINOXHILL ( Tasmania ) suggest to put crushed ice on the plants
to fool the plants to make them think it is winter and then flower
your thoughts
Rod
My daughter visited Spain last year and came home with a gift of ‘real’ saffron for me. As someone who adores cooking, it was just the best gift ever! I was delighted.
Yes Catherine, wouldn’t it be great if we had a suitable climate here in Sydney to grow it.
want to grow my own saffron , but im in Rossmore N.S.W., help
Hi Denise – you will need to be a bit more specific about what kind of help you’re after?
Can crocus sativus bulbs be grown in pots, if so how deep should the pot be?
Hello Rosa,
Crocus bulbs can be grown in pots. Plant them 5 cm deep, just as you would in the ground.
I would recommend using a terracotta pot because they’re porous and dry out a bit quicker.
Marianne
I live in tassy and want to know where do I get bulbs? If anyone could point me in that direction 🙂
Hi Nathan – saffron bulbs are sold in summer when they’re dormant. You can preorder Crocus sativa from Vogelvry Bulbs and Flowers http://www.vogelvry.com.au/crocus-sativus-saffron-crocus/ for despatch in December
Hi.
I live in Paros. Cyclades. Greece.
I got some bulbs from the north greece in kozani. Which is very well known for its saffron.
I got them in July. Had them in my “seed bank”, now they are sprouting like crazy.
Should I plant them in full sun. Well drained and fertile soil.?
Or half shade under the olive trees. Clayish soil.?
Kind regards.
@theo_and_the_garden.
Hello Theo,
You should plant your saffron in full sun into well drained fertile soil.
From my article:
“Plant the bulbs about 5cm (2 inches) deep, preferably in full sun (or somewhere that will be sunny during the autumn/fall flowering period) and make sure the soil drains well. “

I have saffron seeds and cant seem to find out when Im supposed to plant these in Sth Australia.
Question on saffron crocus: does the removal of the stigma harm the flower in any way (life span, multiply corms, etc)?
Also, I live in So Calif. Can I plant the corms in July or Aug?
Thanks.
Hi
I would like to know when or which month I should plant Saffron bulbs in Perth, Western Australia.
Thank you
Hi, I live in Victoria and last year I planted a handful of saffron crocus and every one of them flowered which was just magical. This year the same ones multiplied, but did not flower. Question:-
1. Was I supposed to have pulled out the crocuses and dry them and then replant them in March?
2. If so, is October the month for the crocuses to be taken out of the soil and dried in dark cool place?
Kind regards, Kristin
And if you leave them in the soil while dormant should you cover them with mulch?
Hello Shanthi,
yes planting out bulbs an seeds are different.
Sow the seeds on the surface of your seed raising mix and only cover lightly.
Mist spray with water. Try and keep the mix moist and not dry out.
Crocus seeds need a warm period followed by a cold spell in order to initiate germination, but if the seasonal temperatures are sporadic, dormancy will not be broken and the seed will need to wait until the following year. Any longer than that and the seeds tend to lose their viability.
I live in Hobart and have several saffron bulbs planted. This year, only 2 flowers have appeared. The leaves have shot through the ground but no flowers! Can you suggest a reason for this?
I have been trying Saffron in Canberra for last 3 years, some good success achieved of about 12 flowers this year.
