Lemons, when in the crisper drawer, can last up to about a month. A room temperature lemon will have a bit more flavor than one straight from the fridge.

Native to asia, they're actually a berry that's a hybrid between a sour orange and a citron. One tree can produce up to 600lbs of lemons a year as they produce fruit all year round. Oh, and to power a flashlight bulb, you need 500 lemons wired together ;)

he true lemon tree reaches 10 to 20 ft (3-6 m) in height and usually has sharp thorns on the twigs. The alternate leaves, reddish when young, become dark-green above, light-green below; are oblong, elliptic or long-ovate
