Dendrobenthamia hongkongensis Seeds | Hong Kong Dogwood
LATIN NAME: Dendrobenthamia hongkongensis
COMMON NAME: Hong Kong Dogwood
Plant Profile
The Hong Kong Dogwood is an evergreen tree of the dogwood family from the warm forests of southern China, Vietnam and Hong Kong itself, growing eight to fifteen metres with a neat, rounded crown of glossy, leathery leaves. In spring and again in autumn it carries small, clustered flower heads surrounded by four large, cream-white bracts that look like petals, the dogwood signature, and the display floats over the dark foliage for weeks.
The bracts give way to rounded, bumpy, strawberry-like compound fruits that redden as they ripen and are sweet enough to eat off the tree, a genuine novelty among hardy-ish trees. It is an evergreen dogwood, which sets it apart from the familiar deciduous species, and it flowers on and off through the warm season rather than in a single burst.
Science & Biotechnology
Its classification carries a history: the genus Dendrobenthamia was created for the evergreen, big-bracted Asian dogwoods, and molecular work has since folded them back into a broad Cornus as a distinct subgroup, so older literature files this tree under Dendrobenthamia and newer work under Cornus, with subspecies covering the range of forms. Its repeat-flowering habit, unlike the single spring flush of its deciduous relatives, has been noted in cultivation records, and its edible compound fruit places it in the small set of dogwoods whose crops people actually gather. In its native range it grows in the warm, humid, evergreen forest belt that also holds the camellias and magnolias of southern China.
For growers the practical point is climatic: it wants the warm, humid end of the temperate range, and it is hardy well into maritime Europe but resents continental drought.
Uses & Benefits
In the garden it is a four-season evergreen: glossy foliage, cream bracts on and off through the warm months, edible strawberry-like fruit and a neat, small-tree scale that fits a courtyard or a woodland edge. It pairs naturally with camellias and other acid-soil woodlanders, and its evergreen habit carries the frame through winter.
The fruits are gathered and eaten across its native range, sweet and slightly dry in texture, and the bract displays feed early pollinators at the shoulder seasons when little else is open. It is a collector’s tree in the West, and a familiar village tree at home.
Growing from Seed
Clean the pulp from the ripe fruit and sow fresh into a humus-rich, free-draining compost, leaving the pots in a shaded frame for a natural winter, or cold-stratify for three months before spring sowing; germination follows in the second spring at worst. Keep the trays just moist and shaded throughout.
Grow the seedlings in part shade with steady moisture, pot on deep, and line out for two or three years. Plant out into acid to neutral, humus-rich, moisture-holding soil in light shade, spacing for a ten-metre crown, and mulch annually with leaf mould. Water through dry summers until the roots are down.
Our Take
An evergreen dogwood with cream bracts on and off all season and a sweet strawberry-like crop: a four-season small tree for warm, humus-rich, shaded gardens.
