Citrus sinensis. For a Moro blood orange tree to ripen properly, plant it in front of a stone wall. The retained heat will help the blood orange fruit ripen in early spring. Moro blood orange trees definitely need to be planted in a lot of sun to develop the sugars that make their fruit so appealing in salads and so rich in color. The tart juice has a fresh raspberry flavor. An amazing public garden south of San Francisco, Filoli, grew this citrus tree to perfection on a decomposed granite terrace. The space was a long rectangle, with weeping Camperdown elms at each end. Five blood orange trees were grown in terra cotta pots around each weeping elm, forming a double pentangle. Sublime. Shipped in 4" x 9" pots, trees are about 3' tall with nice branching. TEMPORARILY OUT OF STOCK.
