Lemons are yellow fruits that grow on a small tree or spreading bush. Like limes, oranges, and grapefruit, lemons are citrus fruits. The scientific name of the plant is Citrus limon.
The lemon trees can grow quite tall (to about 3 to 6 meters high) if they are not trimmed. Their leaves are reddish when young, but they turn green. Some trees have sharp thorns next to the leaves.
Lemon flowers are large and have a lovely sweet scent. Lemon trees bloom throughout the year.
The fruit is usually picked while it is still green and is stored for three or more months until its color has changed to yellow.
