Citrus limon 'Eureka' is a vigorous growing small tree, popular because of the tartness of the fruit. It is an attractive, almost thornless variety with large and leathery ovate leaves. It flowers up to 3 times a year.
The “Eureka” lemon tree is an evergreen that produces pink-fleshed lemons all year. The fruit takes up to 9 months to ripen and will hang on the tree for up to 4months so there tends to be fruit for harvesting all year. Young lemons' exteriors are yellow with green streaks and mature to a pale yellow when ready for harvest. New growth on the tree is a bronzed purple color while mature leaves are an apple green. The standard Eureka grows to a height of 20 feet but a smaller dwarf version is available.
