Quick look

The lemon is a species of small evergreen tree in the Citrus genus of the flowering plant family Rutaceae. A true lemon is a hybrid of the citron and the bitter orange. Its origins are uncertain, but some evidence suggests lemons originated during the 1st millennium BC in what is now northeastern India. Some other citrus fruits are called lemon.

Can you eat it?

For peopleNot well documented

None of the sources we checked (NC State Extension (no page for this plant)) say whether it's edible or poisonous for people.

For petsNot well documented

It isn't on the ASPCA plant list. For context only: ASPCA lists a related species, Citrus Aurantium (“Bergamot Orange”), as toxic to dogs and cats. That doesn't tell us about this species, so keep pets away to be safe. ^ASPCA
