Sicilian variety known in the area of Amalfi already in the 19th century. It got it's name because of Luna (luna = moon), it bloomed again and again each month. From Vincenzo Riccatona's monographs (gardener in Palermo Botanical Garden) in 1899: "This new variety deserves to be grown by every citrus grower, not only for its high yields, but also for it's very good blooming that occurs all year long." That's also why it was given such a name: Citrus Limonum semperflorens - Lumiuni lunariu."
It is also grown in other places around the Mediterranean Sea. In the Czech republic it is known also as "Kvaterson", because in Italian it was also called as "the lemon of four seasons" (in every season of the year there is fruit on this tree). It also likes short dry seasons and therefore is suitable for using "Verdelli technique". Then it however produces smaller fruit.
This lemon tree is quite tall and vigorous; it has broad, oval, dark green leaves with a distinctive tip. There are lots of spikes on its branches as well. Flowers are purple and grow either individually or in clusters. Lunario's fruit is average in size (6-7cm), elliptic and almost egg-shaped, usually with a distinctive joint to the branch. The rind is smooth and very thin, when fully ripe, it's yellow and the pulp is green to yellow, neither very juicy nor acidic. It is also very aromatic and divided into 10-11 segments with little or no seeds.
Compared to other cultivars from Italy, it reaches full productivity only in maturity. 'Lunario' is idle for growing indoors and even better in the greenhouses. Sometimes it is also referred to as a clone of 'Amalphitanum'. Some 'Lunario' clones are thornless and some are variegated.
