Description

Crocus cartwrightianus albus or White Saffron Crocus is a lovely hardy autumn perennial, less well known than its cousin sativus. In autumn, it produces large spectacular, beautiful pure white flowers that brighten up the garden. They measure about ten centimetres. Each bulb produces 1 to 3 flowers, whose 3 red-orange filaments are saffron.

The green leaves of Crocus cartwrightianus albus, which are 15 to 20 cm tall, mostly appear after flowering and dry up at the end of spring. The Crocus is used in gardens. It can be placed in a flower bed, border, rockery or even in pots. The Saffron Crocus is a rare species that originates from wild plants in Southern Europe and Asia Minor. Its flowers, unlike most species, remain open even in darkness.

For a saffron harvest, which is mainly produced in Iran, a daily harvest is required when the flowers have just opened as the flowers have a very short life (48 hours). Saffron can be used to spice up your dish. It takes 150 flowers to produce one gram of saffron.

Planting and care

Plant Crocus cartwirghtianus albus from summer for flowering in autumn (late October). The bulbs should be planted in a warm location, facing south or west, at a depth of 15 cm, in groups of 3 bulbs, with each bulb spaced 8 cm apart. They prefer well-drained soil that has been deeply worked and enriched. A sandy or clay-limestone soil that is not too wet will be perfect. If your soil is too heavy, simply incorporate sand or organic matter during planting. The plant does not need to be watered until the first leaves appear; the first cold weather will bring out the flowers. Leave it in place for several years to obtain beautiful flowers without any special care. This crocus prefers to be grown in groups. To obtain saffron, cut the "saffron stigmas" from your crocuses when each flower blooms, ideally at sunrise to preserve their taste, and let them dry, ideally for about twenty minutes in a slightly warm oven (60°): there's your saffron!
