Arum pictum

A tuberous Arum of the Balearic Islands, Corsica, Sardinia and the Tuscan coast, unusual in its genus for flowering in autumn as the first rains arrive. Leaves grow through the mild wet winter and die back in the hot dry summer, so it is grown as a winter-active, summer-dormant geophyte.
