Autumn crocus (Colchicum Autumnale) is a perennial flowering plant belonging to genus Colchicum and grows up to a height of about a foot (30 cm). This herb bears deep green leaves whose shape resembles tulips. The leaves emerge from a corm - a plump, tuberous base. The flowers of autumn crocus are pale purple or white in color. The seed, bulb, and flower are used to make medicine.

Autumn crocus is widespread in Europe as well as the northern regions of Africa. This herb may be found growing naturally in moist grasslands and forest lands. In several places, autumn crocus is also cultivated.

Autumn crocus has a preference for a fertile soil that is well-drained and located in a sunlit position. This herb has the aptitude to endure shade, but is loathe to arid soil. Autumn crocus can endure a pH varying between 4.5 and 7.5. In effect, the plants of this species are very resilient and can tolerate very low temperatures, up to approximately -20°C. The tuber-like roots or bulbs of the plant are usually dormant, but reasonably enduring and have the aptitude to tolerate soil temperatures as low as -5°C. Autumn crocus is very easy to grow as well as naturalize this plant species in grass. In addition, autumn crocus also grows and thrives well in the midst of shrubs and on the fringes of forest lands. The corms or bulbs of this plant are normally about 7 cm to 10 cm deep inside the soil during July. The best part is that the plants of this species appear to be invulnerable to preying by rabbits. However, it is possible that slugs may show aggression towards the corms of autumn crocus. Moreover, butterflies and bees are drawn by the flowers of autumn crocus.

Autumn crocus is generally propagated by its seeds, which are ideally sown immediately when they mature in the early part of the summer in a cold frame or a seed bed. The germination process may be extremely sluggish and even take as many as 18 months when the temperature is 15°C. It is advisable that you sow the seeds of autumn crocus somewhat sparsely to ensure that they need not be transplanted during their first growth season. During the first summer of the plants' growth, it is advisable to apply liquid nourishment with a view to make sure that they receive adequate sustenance. When the seedlings are dormant, prick them out individually and may be put two seedlings in one pot and continue to grow them in a cold frame or greenhouse for a minimum period of two years. You need to transplant the seedlings in their permanent positions outdoors while they are still dormant. Autumn crocus seedlings take as many as four to five years to blossom.

Alternately, autumn crocus can also be propagated by means of the division of the bulbs during June or July when the leaves of the plant have withered away. In effect, it is possible to plant the comparatively bigger bulbs straight away into their permanent positions outdoors. However, autumn crocus is ideal to plant and grow them in containers in a cold frame for about one year prior to planting them outdoors. It may be noted that plants of this species may be divided every alternate year if you desire to grow them quickly.

It may be noted that the seeds of autumn crocus are harvested during the early part of summer, while the tubular corms are dug up during the period between mid to the latter part of summer, when the plant has completely withered away. The corms of the herb are dried up for use when required later.
