As Dillenia speciosa in Curtis Botanical Magazine

The Dillenia, native to tropical Asia, forms a handsome ever green tree that is well suited for ornamental purposes. The trunk usually branches a few feet above the ground, forming a spreading tree that reaches a height of 20 to 25 feet (6 to 7.5 m). The oblong or obovate, toothed leaves are up to 12 inches in length (30 cm) and have many conspicuous parallel veins. The leaves are shiny dark green above, light green beneath, and are confined to the ends of the branches.

Blooming Habits:
The beautiful, solitary, white flowers are very large, sometimes measuring 9 inches in diameter (22 cm). After flowering, the petals drop and the persistent calyx again closes and develops to form a thick fleshy covering enveloping the fruit.

Fruiting Habits:
The fruit, together with its protective covering, measures 5 to 6 inches in diameter (12-15 cm). The many-seeded true fruit is greenish yellow and surmounted by the persistent, slender, spreading rays of the stigma. The juicy pulp is aromatic but very acid and requires cooking. Unripe fruits are also cooked and pickled.

Culture:
The dillenia can be propagated readily by seeds but with difficulty from cuttings. It can be grown on many types of soils, but does better on acidic sandy loams.
