The red lemon, also known as limon rosso or limone rosso ISA,[1] and botanically classified as Citrus limonimedica 'Pigmentata', is a species of small evergreen tree in the Citrus genus of the flowering plant family Rutaceae. It is a hybrid of the lemon and the citron.[2] The tree's fruits, also referred to as red lemons, resemble a red or deep orange version of a true lemon, both outside and inside.[2][3] Red lemons have a short shelf life, typically lasting only two or three days, and thus they are not often grown commercially.[2] It is instead typically cultivated on a small scale through specialty growers,[2] especially in eastern Sicily, near Syracuse.[4] It is also grown as a novelty fruit tree in home gardens in Italy.[2]

Description

The tree is an evergreen[3] and is of medium vigor.[1] It has a globose canopy, with branches that are not very spiny.[1] The foliage is variegated.[3]

The tree is of medium re-flowering.[1] It blossoms in the spring and summer.[2] The flowers are white and medium perfumed.[1] These flowers are either single or in small groups.[1]

Fructification is early and medium abundant.[1] The fruit is large, very persistent, ellipsoidal, having been described as an "almost elongated 'drop'" shape,[3] with a large apical nipple and an intense, attractive anthocyanic red color on 70-80% of its surface when ripe.[1]

Origins

The origin appears not to be known with certainty.[1] At least one source states that it is believed to be native to the Mediterranean region.[2]

Alternative names

The red lemon is also known by many other names across Europe, including rosso lemons, limone rosso, mulled wine lemon, red citron, blushing lemons, and red pigmented lemons.[2]
