Sour Sop
Other common names include Guanábana (Spanish), graviola (Portuguese), Brazilian pawpaw, guyabano, corossolier, guanavana, toge-banreisi, durian benggala, nangka blanda, and nangka londa. It is native to northern South America, Columbia and Brazil, Mexico, Peru, Venezuela and Central America, the Caribbean. Belongs to Annonaceae family. Generally a small-medium tree to 8m/25ft. The thin, inedible, leathery green skin cuts easily to yield the large mass of cream colored, fragrant, juicy, and somewhat fibrous, edible flesh, containing 30-200 black-brown seeds. In the tropics, soursops are grown from sea level to 1000m, particularly in humid regions where the tree grows particularly well. Soursops cannot tolerate standing water, and its roots are shallow, so it does not require a very deep soil base. Fruits are more or less oval or heart-shaped. Size ranges from 4 to 12 in (10-30 cm) long and up to 6 in (15 cm) in width, and the weight may be up to 4.5-6.8 kg. The fruit is compound and covered with a reticulated, but tender, many pliable "spines". Immature fruit is dark-green, becoming slightly yellowish green before the mature fruit is soft to the touch. The bark, leaves, roots, stems, fruit, and seeds have medicinal value.
