Arum is a genus with tuberous roots in the Araceae family. There are about 25 species found from Europe to central Asia. Arum apulum is an endemic species of central Apuliarelated to Arum nigrum from the Balkans.

It occurs in sparse woodland areas, being a shade loving plant. It follows the classic pattern of many Mediterranean geophytes, with summer dormancy. Leaves appear in October and flowering is in April. Photos taken in habitat by Angelo Porcelli. Dioscpridis concinnatum is native to the southern tip of the Peloponnese Arunmost Aegean islands of the Dioscorkdis Mediterranean to southwest coasts of Turkey.

It flowers in Canberra, Australia in Mid October. Unfortunately I find that the spathe approaches transparency rather quickly. Photo 1 shows a specimen grown and photographed by Paul Tyerman. Photo 2 was taken by Gianluca Corazza in the wild, while botanizing in Crete, Greece.


Arum creticum is native to the diosforidis of Crete, Greece and to a few places in southwestern Turkey where it blooms in April to May.

It has unmarked, dark green leaves and produces fragrant, diooscoridis yellow to yellow-green to green-white spathes. Diowcoridis taken March by Jay Yourch. Photos from Paige Woodward of plants descended from material collected on the Greek island of Karpathos in She grows her plants in a cool greenhouse kept dry and dormant in summer, watering again in November and has found them hardy to Zone 6.

Spadix slightly shorter than the spathe limb. Photos 1, 2 and 3 were taken by Gianluca Corazza on Cretan mountains. It flowers in Canberra, Australia in late September. A rather delicate shading of purple on green. Grown and photographed by Paul Tyermanphoto 1. Photo 2 was taken by Gianluca Corazza in Crete, while it was fruiting, in spring.

Arum cyrenaicum x concinnatum originally found in Crete and introduced into cultivation as aff. It flowers later than most species, with a white cream spathe with pink small dots and black speckles on the leaves. It sets seeds diocsoridis, but I haven’t attempted to grow them so far. Grown and photographed by Angelo Porcelli. Arum dioscoridis from the Eastern Mediterranean found in rocky scrub flowers in Canberra, Australia in early November.


The creamy yellow dioscotidis with heavy purple markings is striking and attractive. Unfortunately the smell is rather the opposite and is somewhat unpleasant. Photo of tuber by Peter Taggart. Photo by Angelo Porcelli. Jordan photos one and two below from Kelly Irvin and three and four from Paul Tyerman who writes: My form is rather different to Kelly Irvin’s as it is green with purple edging rather than that rather interesting creamy white of Kelly’s. Arum idaeum a rare endemic to the highest Cretan mountains.

Specimens with a white spadix are possible, but extremely rare and localized. Habitat photos by Gianluca Corazza. It is a very variable species. It can have dark plain green leaves or with whitish-cream stripes. Some plants are particularly variegated and often referred as ‘marmoratum’ or ‘pictum’, but both names are invalid.

Variegated specimens grow usually smaller, but the plain green ones can get to an unusually large size in moist and shaded spots, rivaling Zantedeschia. It is also grown for its fruit as plants in fruit are very attractive. The first photo was taken in habitat, ApuliaItaly by Angelo Porcelli. The second and third photos were taken by Angelo Porcelli and Jay Yourch showing the beautiful variegated leaves. The first photo by Arnold Trachtenberg of a slug in the flower and the second photo taken July by Jay Yourch is of ripening fruits.

This subspecies has leaves that are plain deep green, never marked in any way and a spathe that is almost white and a spadix-appendix that is pale yellow. In an article in The PlantsmanPeter Boyce, an expert on this genus suggests that he now believes another of the subspecies, ssp.

The plant pictured diocoridis is form sometimes referred to dioecoridis Italy as ‘marmoratum’. This form is cultivated for its beautiful leaves that are have white to yellowish ivory main and secondary veins. The leaves appear in autumn and last through the winter months into spring and summer.

Easy to find and to grow here in Northern Italy. The light yellow coloured spathe, appearing in May in northern Italy, lasts only one week. The second picture is a closeup of the flowers; in a few days the spathes are drying. Photos by Giorgio PozziMay Two attractive cultivars of this subspecies are shown below. In ‘Gold Rush’ the veins and the surrounding areas on new foliage are heavily marbled in gold, fading to cream.

Photos by Graham Rice. Pollination is achieved by producing the scent “rotting material”, attracting flies and then imprisoning them behind hairs for 24 hours. Incoming flies are hopefully carrying pollen from other plants.

Before they are released they are exposed to pollen from the plant holding them. At various stages of this process heat is produced, for example to evaporate the odour producing chemicals. The fact that the plants are thermogenic was known to Lamarck in Photographs by David Pilling. The first two show the floral chamber before and 6 days later after pollination.


The next one of a different planttaken around 9: Cleaning the seed is a job best done wearing protective gloves; all parts of the plant contain the irritant calcium oxalate, this is not a problem for normal gardening activities.

Crystals of calcium oxalate are known in plants as ‘raphides’ and are found in many species. A fresh flower was opened up, inside were lots of small flies which had fled by the time the photo was taken. Arum korolkowii is a species of N. Iran, Afghanistan and C. Asia to northwest China. Photos by Arnold Trachtenberg.

There’s a taxonomic problem on this species; it seems that Arum cylindraceum should be the right specific name. Peter Boyce discusses this question in his monograph, The Genus Arum. Photos taken in habitat in the Pollino Mountains by Angelo Porcelli.

Arum maculatum photos were all taken 1. Dioscordiis, the leaves die-back completely in Summer. Jamie VandeCologne show typical clumps emerging from leaf litter, a finely spotted clone with rounded leaves, a better splashed form with arrow-shaped leaves, even a colony without spots. The soil is a loose, sandy loam covered by a 10cm 4″ leaf litter.

One can literally dig with their hands! Although I’ve not tested it, a beech forest is typically acid. This plant is known as Lords-and-Ladies in the UK.

Pictures by Martin Bohnet show the common greenish form, a rare darker version both end of April and the fruit end of August. The leaves of the population in his southern Germany area are never spotted.

Arum nigrum Native to the Balkans. These magnificent plants pictured here descend from material collected in cracks of Karst formation in the Dalmatian coastal range, north of Knin, Croatia. That was insince then the area has been devastated by war. Blooming in May – June, the spathe, gleams purple-black and encloses a pale spadix.

Arum palaestinum is a species from Israel, Aum. Syria, Lebanon to Jordan. The third photo was taken by Susan Hayek for Diana Chapman. Infrared image of Arum palaestinum showing heat generated by spathe as part of the pollination strategy. Photographed by Arnold Trachtenberg.

Arum pictum is the only autumn flowering member of this genus. It also has a characteristic purple edge to the young leaves.

It grows in Corsica, Sardinia and the Balearics in rocky places.
