Elephant Ear Fig Facts

Plant Description

Elephant Ear Fig is an evergreen to semi-deciduous, wide-spreading, small tree that normally grows about 5–10 m (16–33 ft.) high with a stem diameter of 10–15 cm. The plant is found growing in forests in moist valleys, in midlands and mountainous areas, windbreaks of the forest, in forest clearings, or at the edge of rain forests. The plant thrives in loose, moist, friable soil, rich in organic matter. The bark is greyish brown and rough. Young branches are thin, reddish-brown, pubescent, with the leaves concentrated in the terminal part. Stipules are reddish-purple, triangular-ovate, 1.5–2 cm, adaxially shortly pubescent. The plant is leafless in the middle of the stem and is pubescent.

Leaves

Leaves are alternate on thick, 8–15 cm long petiole and are clustered towards the stem apex. Leaf-blade is broadly ovate-cordate, large, 15–55 cm long and 10–27 cm wide, thickly papery, abaxially pubescent, adaxially glabrous, or puberulent on midvein or secondary veins, base cordate or rounded, margin regularly shallowly dentate, apex obtuse and mucronate. Basal lateral veins 4–6, secondary veins 3 or 4 on each side of the midvein. It is papery, densely small tuberculate on the underside, and hairless above. The young leaves are intensely red, and turn more and greener till they reach their ultimate size of up to 30-40 cm in diameter.

Flower

Flowers are unisexual.  The inflorescence is hypanthium; both the male and female flowers are borne on the fleshy receptacle. The male flowers are 4 mm long and the female flowers are 6 mm long.  Calyx and the corolla are modified into threadlike scales. Stamens are very small, about 2 mm long, style is long, deeply two-branched and single, ovoid ovary. Flowering normally takes place from the first week of March and continues till the end of April.

Fruits

Fertile flowers are followed by clusters of figs on short branchlets of old stems, sometimes even on the roots of the tree. They are pear-shaped to spherical, with 4-6 longitudinal ridges and small tubercles. They are 2-3.5 cm in diameter, covered with soft hairs. They are initially green, turning to brown or reddish-brown, and glabrescent when mature. The fruit is, in fact, a fleshy receptacle, enclosing a number of true fruits or achene’s, which develop from the female flowers lying within this receptacle. They are edible and sweet and are used to make jams, juices, and curries in India. Unripe fruits are also used in Vietnam in salads. Leaves are used as fodder for ruminants.
