Chinotto Sour Orange

Chinotto, also called myrtle-leaf orange, is a sour-orange selection. UCR lists the parentage and origin of CRC 2375-B as unknown and records receipt of a live plant in 1930; that collection date does not establish the cultivar’s origin.^{⁠[2]⁠[14]}

UCR describes Chinotto as slow-growing and compact, with small dark pointed leaves densely carried on thornless shoots. Its small orange fruit ripens in winter and can remain on the tree for much of the year, giving it ornamental value.^⁠[1]

Fruit descriptions vary by sample. UCR’s 2008 observation calls the fruit small and seedy and says it hangs on the tree as ornamental fruit. One video speaker reported almost no seeds in a single outdoor fruit, while separate purchased fruit and a Houzz comparison were described as seedy. Another single-fruit comparison found the Chinotto smaller than Seville. Sample dates, sites and maturity are mostly unspecified.^{⁠[14]⁠[3]⁠[4]⁠[11]}
