A luxurious, vivid spice that has been around for centuries, saffron comes from a flower called crocus sativus, also known as the ‘saffron crocus’. A beautiful, purple flower with bright red threads (stigmas), these threads are what make the saffron spice. Saffron can only be harvested by hand over a short period of time in the fall season, with each flower only producing a very small amount of the spice, which explains why saffron is one of the most desired and expensive spices in the world. Here we explore how to grow saffron at home and address some of the most common questions asked about this unique and valuable spice.
How to grow saffron
Below we take you through our simple step-by-step guide on how to grow saffron.
To grow saffron at home, you will need to buy some crocus sativus (saffron crocus) corms or bulbs, the more you have, the more saffron you will be able to harvest. Plant the bulbs in late summer. They can be planted in grass in well-drained soil, as well as in pots or in a cool greenhouse. If planted in grass, the plants are great for edging a path or border, or work well in clusters in a flower-bed or rockery.Plant the bulbs in small clumps, around 5cm deep and 5-10cm apart. Once planted, ensure the soil gets plenty of sunshine and does not become waterlogged. The flowers will bloom in fall before the leaves. The bright red threads must be picked and dried quickly as the flowers unfortunately wilt after just one day. Delicately remove the threads using tweezers, each flower produces only three stigmas.Leave the threads on a paper-towel indoors for a few days until they are fully dried out, then store in an air-tight container in a warm, dry place. You can then crush the stems to make a powder and add the saffron to many a recipe, both sweet and savory, with the spice adding a sweet, earthy taste.After the plants have flowered, leave the plant to die naturally and prune when it turns yellow.
