Plant Myristica fragrans

Spice:

Nutmeg

Botanical Name:

Myristica fragrans

Botany:

Myristica fragrans is an evergreen tree, usually 5–15 m (16–49 ft) tall, but occasionally reaching 20 m (66 ft) or even 30 m (98 ft) on Tidore. The alternately arranged leaves are dark green, 5–15 cm (2.0–5.9 in) long by 2–7 cm (0.8–2.8 in) wide with petioles about 1 cm (0.4 in) long. The species is dioecious, i.e. "male" or staminate flowers and "female" or carpellate flowers are borne on different plants, although occasional individuals produce both kinds of flower. The flowers are bell-shaped, pale yellow and somewhat waxy and fleshy. Staminate flowers are arranged in groups of one to ten, each 5–7 mm (0.2–0.3 in) long; carpellate flowers are in smaller groups, one to three, and somewhat longer, up to 10 mm (0.4 in) long. Carpellate trees produce smooth yellow ovoid or pear-shaped fruits, 6–9 cm (2.4–3.5 in) long with a diameter of 3.5–5 cm (1.4–2.0 in). The fruit has a fleshy husk. When ripe the husk splits into two halves along a ridge running the length of the fruit. Inside is a purple-brown shiny seed, 2–3 cm (0.8–1.2 in) long by about 2 cm (0.8 in) across, with a red or crimson covering (an aril). The seed is the source of nutmeg; the aril the source of mace.

Cultivation:

Nutmeg trees are dioecious plants (individual plants are either male or female), which are propagated sexually from seeds and asexually from cuttings or grafting. Sexual propagation yields 50% male seedlings, which are unproductive. Because no reliable method has been found for determining plant sex before flowering in the sixth to eighth year, and sexual reproduction bears inconsistent yields, grafting is the preferred method of propagation. Epicotyl grafting (a variation of cleft grafting using seedlings), approach grafting, and patch budding have proved successful, with epicotyl grafting being the most widely adopted standard. Air layering is an alternative though not preferred method because of its low (35–40%) success rate. The first harvest of nutmeg trees takes place 7–9 years after planting, and the trees reach full production after 20 years.
