Habitat :Arum dioscoridis is native to forests in the east of the Mediterranean in southern Turkey, Cyprus, and the Middle East.It grows in hedges and rocky places, often on calcareous soils.
Description:
Arum dioscoridis is a perennial plant growing to 0.3 m (1ft) by 0.3 m (1ft in). It is not frost tender. In winter appear green, arrow-shaped leaves. In spring, the short-stalked inflorescence appears consisting of a black, rod-shaped spadix surrounded by a yellow-green, purple-mottled brown or even purple bract (spathe). The female flowers are located at the bottom of the spadix; above are the male flowers; and the top is a sterile area (appendix). The spadix emits a pungent smell that attracts flies as pollinators.

It is in leaf 7-Oct It is in flower in May. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Flies.Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It prefers moist soil.
Cultivation:
Prefers a humus rich soil and abundant water in the growing season. Grows well in woodland conditions. Succeeds in sun or shade. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c. Because it comes into growth in the late autumn it is best grown by a warm wall or in a bulb frame A polymorphic species. The inflorescence is pollinated by flies and it smells of dung and carrion in order to attract the flies. It also has the remarkable ability to heat itself above the ambient air temperature to such a degree that it is quite noticeable to the touch. This probably protects the flowers from damage by frost, or allows it to penetrate frozen ground. Members of this genus are rarely if ever troubled by browsing deer.

Propagation:
Seed – best sown in a greenhouse or cold frame as soon as it is ripe. The seed usually germinates in 1 – 6 months at 15°c. Stored seed should be sown in the spring in a greenhouse and can be slow to germinate, sometimes taking a year or more. A period of cold stratification might help to speed up the process. Sow the seed thinly, and allow the seedlings to grow on without disturbance for their first year, giving occasional liquid feeds to ensure that they do not become mineral deficient. When the plants are dormant in the autumn, divide up the small corms, planting 2 – 3 in each pot, and grow them on in light shade in the greenhouse for a further year, planting out when dormant in the autumn. Division of the corms in summer after flowering. Larger corms can be planted out direct into their permanent positions, though it is best to pot up the smaller corms and grow them on for a year in a cold frame before planting them out.

Edible Uses :
Edible Parts: Root…..Tuber – cooked and used as a vegetable. It must be thoroughly dried or cooked before being eaten, see the notes above on toxicity.
Medicinal Uses : Abortifacient….The root is abortifacient.
Other Uses:
The plant can be grown as an ornamental plant in rock gardens Mediterranean regions. In the Benelux, the plant can be grown indoors as a pot plant. The plant can be propagated by seeding.
