Fig tree
Ficus carica

How to tell it
A large leaf, rough as sandpaper, cut into three to five rounded lobes. Any broken part bleeds sticky white latex. A characteristic leaf smell when rubbed. It grows where it should not, clinging to stone.
What it is confused with
Black mulberry
Morus nigra
Same family, same rough lobed leaf. Mulberry bleeds no white latex when broken and bears elongated berries; fig always bleeds latex. Both bear edible fruit.
What it is for
The ripe fig is eaten fresh or dried and is an ancient crop across the Mediterranean. A warning that belongs on the sheet: the latex of leaves and unripe figs contains furanocoumarins and, with sun exposure, causes severe skin burns. Picking figs in morning sun with bare arms is how people get marks that last weeks.
Traditionally used as food. This is not permission to eat it.
