Spoon-leaved Coprosma

Botanical name: Coprosma spathulata
Synonyms: None
Common name(s): Spoon-leaved Coprosma

About:
Coprosma spathulata is a distinctive North Island shrub recognised by its spoon-shaped leaves, prominently winged leaf stalks and stiff hairy branchlets. It is a forest understorey species that thrives in sheltered environments and is often associated with kauri forest and regenerating native scrub. The foliage is frequently mottled with yellow, pale green or purple markings, making it an attractive native ornamental plant.

Natural habitat:
Occurs naturally in coastal to montane forest, especially lowland forest, kauri forest, mixed hardwood forest, riparian forest, alluvial forest and regenerating scrub.

Growing environment:
Prefers sheltered positions in moist, fertile, free-draining soils. Grows best in partial shade beneath a taller shrub or tree canopy and dislikes prolonged drought or exposure.

Endemic distribution:
Endemic to New Zealand. Confined to the North Island from Te Paki south to Waitomo in the west and near Gisborne in the east.

Height:
1–3 m

Width:
1–2 m

Flowering:
June–October

Fruiting:
July–June

Uses:
• Native forest restoration
• Understorey planting
• Riparian restoration
• Wildlife habitat planting
• Native woodland gardens
• Shade-tolerant ornamental shrub

Appearance:

Growth habit:
An erect, bushy shrub with slender widely spreading branches. Plants are often narrowly upright when young but become more branched and spreading with age.

Trunk and branches:
Branches and branchlets are slender and densely covered with short stiff hairs, giving them a rough texture. Young stems are noticeably pubescent and help distinguish the species from similar coprosmas.

Leaves:
Leaves are borne in opposite pairs and are thick, leathery and glossy. They are spoon-shaped to broadly rounded, typically 10–20 mm long and wide, narrowing abruptly into a distinctive flattened winged leaf stalk. The upper surface is dark green and often mottled with yellow, pale green or purple blotches, while the underside is paler. Small domatia occur beneath the leaves where the lateral veins meet the midrib.

Flowers:
Flowers are small, greenish-white and borne singly or in pairs on short branchlets. Male and female flowers occur on separate plants.

Fruit:
The fruit is a fleshy drupe, 6–8 mm long, varying from dark orange and red to deep purple-black when ripe. The berries are rounded to slightly oblong and are attractive to native birds.

Ecology:
The fleshy fruit is dispersed by birds (frugivory), helping the species colonise forest margins and regenerating habitats. Its dense branching structure provides shelter for insects and small birds.

Associated habitats:
Kauri forest, mixed hardwood forest, riparian forest, alluvial forest, lowland forest, montane forest, mānuka scrub, kānuka scrub and regenerating native shrubland.

How to grow:
Plant in a sheltered position with moist, free-draining soil. It performs best in partial shade beneath a light canopy. Regular moisture during establishment improves growth, while mature plants require little maintenance.

Propagation:
Easily propagated from fresh seed and semi-hardwood cuttings. Seed germinates readily when fresh and cuttings strike reliably under suitable conditions.

Cultural use:
As a component of northern New Zealand forests, spoon-leaved coprosma contributes to the ecological diversity of native ecosystems and supports native bird populations through its fruit production.

Garden value:
Spoon-leaved coprosma is valued for its unusual rounded foliage, colourful leaf markings and attractive berries. Its tolerance of shade makes it an excellent choice for woodland gardens, native understorey plantings and ecological restoration projects.
