I thought A. maculatum was a synonym of A. italicum subsp. maculatum? Is 
that wrong?

It's interesting that Arum pictum is endemic to Sardinia. I bought the 
plant some years ago from an English nursery and read that it was tender, 
so I kept it in the bulb frame. Last fall I planted out some extra offsets, 
admittedly in one of the warmer parts of the garden, and they made it 
through a harder than average winter with no damage to the winter-growing 
foliage (low of 17 F, repeated snowfalls and thaws).

I planted out a number of different Arum species on a steepish slope last 
fall and hope most of them will prove hardy and eventually clothe the slope 
in winter and spring with their foliage. Several have flowered in the bulb 
frame, including A. dioscoridis, which is beautiful but smells just like 
cow manure (not that bad, as aroids go).

Several years ago I organized a special issue of the Rock Garden Quarterly 
devoted to aroids (a few copies are available for purchase through the Book 
Service), and Peter Boyce was kind enough to contribute an article on the 
genus Biarum. I've managed to grow a number of these mostly smaller aroids 
(some can get quite big, as I found out when I finally saw them in nature), 
which are fairly easy from seed. Some of them don't produce many offsets, 
though, so I don't often have enough to distribute.
