Original inflorescences
Europe, Middle East


The genus Arum belongs to more than 20 herbaceous rhizomatous perennials. These are monoecious plants with a rounded tuber shape. They are characterized by long spear-shaped leaves (in the form of an arrowhead), growing on long petioles from the base of the plant. The leaves have very pronounced veins. The inflorescence is an ear (with a colored thickened main axis), wrapped in a very bright bract (reborn leaf) - the so-calledе cover. Autumn on the Arum are formed very decorative red berries. Arum italicum is an unpretentious species with decorative whitish veins on the upper side of the leaves, which often last all winter, but in summer they dry out quickly enough. A yellowish coverlet encloses a light -yellow cob inside. Common varieties: 'Chameleon', whose leaves are covered with a marble gray-green and yellowish-green pattern, and 'Painted' - with thin leaves in white streaks.

On the Cretan arum (A. creaticum) in spring, very bright flowers with yellow veils are formed, from which long yellow cobs peek out; leaves of a beautiful dark green color.

Arum Dioscorides (A. dioscoridis) - a delicate species with a characteristic blanket color: purple or light green with black spots.

Arum mottled (A. maculatum) - resistant species; leaves are covered with black spots; inside the cover is a purple-pink cob.

Arum Palestinian (A. palestinum) is native to the Middle East. It is a delicate species with leaves about 15 cm long. A blanket, greenish on the outside and blackish-red on the inside, wraps the ear-also black.

Such species as arum Italian are usually grown in the garden, in the open ground, but they can also be planted in pots. However, during the winter months, it is mandatory to cover the pots with straw or other similar materials. Tender species, such as the Palestinian Arum, can tolerate open ground conditions, but only in temperate climates. Therefore, it is better to grow them in pots, so that it is possible to remove plants for the winter in a closed room. Arum requires fertile soil. When growing in a pot, a very well-drained soil rich in organic matter should be used.


Arum prefers a partially shady location.


For sensitive species, the air temperature during cultivation should not fall below 7 °C, hardy species tolerate a drop in temperature to -10 °C. The optimal temperature is 14-22°C.


The Arum in a period of growth requires low soil moisture and at rest (in the summer) he generally prefers the dried soil.


The plants are transplanted into a new pot in the spring, while separating them at the same time.


Arum propagated in early spring by dividing the tuberous rhizomes.

Diseases and pests

Phytophthora can cause rotting of roots and rhizomes. The leaves dry, and the flowering is less intense. Another fungus of the genus Phylostictosis provokes the appearance of brown spots on the leaves. You can get rid of these infections by treating the plants with fungicides. The defeat of the causative agent of the black leg (Erwinia carotovora) leads to the fact that the rhizomes become limy, wet and spread an unpleasant smell, and the leaves turn yellow. The plant affected by bacteriosis is discarded.

Tiny nematode worms present in the soil cause growths (galls) to appear on the roots. Aphids, mites and thrips sometimes settle on the stems and leaves of plants, all of which are disposed of by treatment with appropriate insecticides.


The Arum are grown rare, and get this plant is not easy. Rhizomes can be found in individual gardening centers and specialized flower nurseries.
