English: sweet cherry Spanish: cereza Estonian: kirss Portuguesse: cereja Albanian: qershi Turkish: kiraz Catalan: cicera FRUIT The fruit is a drupe 1–2 cm in diameter (larger in some cultivated selections), bright red to dark purple when mature in midsummer, edible, variably sweet to somewhat astringent and bitter to eat fresh. Each fruit contains a single hard-shelled stone 8–12 mm long, 7–10 mm wide and 6– 8 mm thick, grooved along the flattest edge; the seed (kernel) inside the stone is 6–8 mm long Leaves The leaves are simple ovoid- acute, 7–14 cm long and 4–7 cm broad, glabrous matt or sub- shiny green above, variably finely downy beneath, with a serrated margin and an acuminate tip, with a green or reddish petiole 2–3.5 cm long bearing two to five small red glands. The tip of each serrated edge of the leaves also bear small red glands. In autumn, the leaves turn orange, pink or red before falling FLOWERS The flowers are produced in early spring at the same time as the new leaves, borne in corymbs of two to six together, each flower pendent on a 2–5 cm peduncle, 2.5–3.5 cm in diameter, with five pure white petals, yellowish stamens, and a superior ovary. The ovary contains two ovules, only one of which becomes the seed.
