Grapefruit grows on trees that can get really tall. It can be pale yellow to dark pink or red, and it has a flavor that ranges from bittersweet to sour. It's a happy accident that resulted from the crossing of a sweet orange and a pomelo.

Examples:

1. I sprinkled some sugar on the grapefruit to balance the tartness.
2. We used grapefruit juice and sparkling water to make a summer soda.
3. If you take medication, be sure to talk to your doctor before eating grapefruit.
