Acerola is an evergreen shrub or small tree with spreading branches on a short trunk. It is usually 2–3 m (6.6–9.8 ft) tall, but sometimes reaches 6 m (20 ft) in height. The chromosome number is 2n = 40. Bark The bark of young branches is green and sparsely covered with curly-haired trichomes, which fall off with age. The greyish to brownish bark is relatively smooth and covered with conspicuous cork pores when young. With age, it is thick and cracked. Leaves The leaves are simple, ovate to elliptic-lanceolate in outline, 2–8 cm (0.79–3.15 in) long, 1–4 cm (0.39–1.57 in) wide, with an entire or undulating margin. They are attached oppositely on the stem on short petioles. These leaves and petioles can irritate skin due to minute stinging hairs. Flowers The tree flowers from April to November. Flowers are bisexual and 1–2 cm (0.39–0.79 in) in diameter. They have five pale to deep pink or red fringed petals, 10 stamens, and six to 10 glands on the calyx. The three to five flowers per inflorescence are sessile or short-peduncled axillary cymes. Fruits and seeds Three years after planting, trees start producing fruits. 3–4 weeks after flowering, a number of bright red drupes 1–3 cm (0.39–1.18 in) in diameter with a mass of 3–5 g (0.11–0.18 oz) mature. The shell of the fruit is smooth and very thin. Its shelf life of 2–3 days at ambient temperature makes it highly perishable. Drupes are in pairs or groups of three, and each contains three triangular seeds. The drupes are juicy and high in vitamin C (3–46 mg/g or 1.5–20 grains per ounce) and other nutrients. They are divided into three obscure lobes and are usually acidic to subacidic, giving them a sour taste, but may be sweet if grown well.
