Graviola (Soursop) trees are bushy and low, only about 7.5-9 m tall. Young branchlets are rusty-hairy. The smooth, glossy, dark green leaves are oblong to elliptical and pointed at both ends. Solitary flowers emerge anywhere on the trunk, branches or twigs. They are cone shaped, the 3 fleshy outer petals are yellow-green, the 3 inner petals are pale-yellow. The fruit is more or less oval or heart-shaped, though it tends to be lopsided or curved.
