Grapefruit

The evergreen grapefruit trees usually grow to around 5–6 m (16–20 ft) tall, although they may reach 13–15 m (43–49 ft).^[1] The leaves are long (up to 15 cm (5.9 in)), thin, glossy, and dark green. They produce 5 cm (2 in) white four-petaled flowers. The fruit is yellow-orange skinned and generally an oblate spheroid in shape; it ranges in diameter from 10 to 15 cm (3.9 to 5.9 in). Its flesh is segmented and acidic, varying in color depending on the cultivars, which include white, pink, and red pulps of varying sweetness (generally, the redder varieties are the sweetest).^[1] The 1929 U.S. ‘Ruby Red’^[1] (of the ‘Redblush’ variety) was the first grapefruit patent.^[5]
