This seedless, late season navel ripens from Jan-May long past the regular ripening season of most of the common navel oranges. Originally from Australia, Autumn Gold is one of the best new varieties in terms of fruit quality for sweet flavor and juiciness. In some of the trials, fruit held on the tree until June. Citrus plants make ideal container specimens for northern gardeners. Grow in a large container and let the plants summer outside. This is a grafted plant that blooms and fruits sooner.
