Description

Mountain soursop is an evergreen or semi-evergreen deciduous shrub or small tree that normally grows about 3 – 14 meters tall. The tree slightly resembles that of the soursop but has a more spreading crown and very glossy leaves. It is slightly hardier and bears more or less continuously. The plant is drought tolerant and will grow well in dry conditions but cannot withstand prolonged waterlogging. The plant is tolerant of a wide range of well-drained, fertile soils, but prefers a moist, sandy loam.  It is harder than many other tropical fruit trees, capable of tolerating temperatures below freezing for brief periods.

Leaves

Leaves are alternate, distichous, shortly petiolate, oblong or elliptic 7–18 cm long by 2.5–8 cm wide, with tapering apex and rounded base, leathery, dark green above and pale green beneath, glabrous and glossy.

Flowers

Flowers are solitary or in pairs in older twigs, with stout peduncles. Sepals are three, broad and pubescent; petals 6 in two whorls, inner three are rounded; stamens numerous and crowded in rounded mass.

Fruits

Fruits are nearly round or broad-ovoid, about 15 cm (5.9 inches) long and 7–13 cm wide.  Its dark-green skin is studded with numerous short, fleshy spines and dark brown hairs. Fruits are initially green turning to yellow and very soft when ripe and fall down. Fruits have a yellow, fibrous flesh that is aromatic, sour to bitter, and contains many light-brown, oblong plump seeds about 18 mm long. Fruits are considered inferior to the soursop, so although it is occasionally cultivated, commercial production is not frequent.

The fruit of mountain soursop is edible but many people consider it tasteless, although some varieties produce better quality fruits. It has bitter or sour flesh but it is otherwise similar to the normal soursop, better known as the guanabana. Mountain soursop trees bear fruit more or less continuously starting two to three years after planting.
