Grow your own saffron (the most expensive spice in the world), with this beautiful crocus. It produces large, rich lilac flowers with distinctive purple veins in October and November. An autumn-flowering crocus, it is named after its three long, deep-red stigmas, which are cultivated commercially for colouring and flavouring food. To provide the conditions in which it needs to thrive, plant the bulbs in August or September in gritty, well-drained soil.
Garden care: Plant bulbs in naturalistic drifts 10-15cm (4-6in) deep from August onwards in gritty, well-drained soil. Where bulbs are planted in grass do not cut the lawn until after the leaves have died back.Please note that as these autumn flowering crocus have an incredibly short shelf-life, it is quite common to see them already flowering when they are delivered. This will not have an adverse effect on the the long-term health and vigour, and the ones that have not started to flower should be planted out as normal, taking care not to damage any emerging shoots. Those that have started to flower should be taken out of the bag and placed on a sunny windowsill where you can enjoy the show. As soon as the flowers have faded (and before the leaves develop) these too can be planted out.
