Hi Tom,


In the Mediterranean the ripe fruits stay on the peduncle for a long time, and generally are collected by thrushes or blackbirds (Turdus spp.) late in summer, as the autumn/winter rains begin. The seed passes through the bird, either via regurgitation or through faeces, but the important thing is that the red pericarp and pulpy mesocarp is removed


The fruits  should be cleaned of the pulp and sown on the surface of a mineral-soil rich mix and covered to ca. ½ inch with small chippings (1/8-1/4 inch), ideally limestone. Water them well and stand the pot someplace shady. Keep an eye on water; don’t let them become totally dry, but equally overwatering is detrimental. They will begin to germinate immediately they encounter moisture but, depending on the species, will either produce an aerial shoot (eophyll) soon after germination (most), or will concentrate on root/tuber production and produce an aerial shoot very early in the new year (maculatum, cylindraceum, orientale).


Very best

Dear Aroiders:


            I just returned from a trip to the Balkans and collected an Arum in fruit in Durres, Albania.  Since these berries were mature in the midst of their dry Mediterranean style summer and if shed directly in such dry conditions could surely not germinate I am assuming that they must somehow survive without germinating until the rains begin.  Does anyone know what I should do to get these seeds to germinate?  Do they need to be stored?  Planted directly?  Treated in any particular way?  I would appreciate you help.  Emily is coming in tomorrow to deal with them so if you have some advise I would love to hear from you.






Pete:  I have copied both you and Marija Bedalov since I know that both of you have had direct experience with Arum.
