Growing Guide
Cabbage trees grow all over New Zealand in a range of habitats from coastal areas through to inland foothills. They particularly favour the alluvial soils of flood plains, swamps and lakesides where they like growing in full sunlight. As tī kōuka grow old and stems die, shoots can grow from the trunk. Cabbage trees are quick growing and tolerate very wet soil. They are frequently found in wetlands but are also widespread in other habitats. Because they produce masses of seed, they are an ideal species to colonise disturbed areas or re-vegetate riverbanks but fail to thrive once other trees shade them out.

Propagation: Sow thinly on a firm bed of seed raising mix and cover lightly with mix.
Seedlings begin to appear two to four months depending on temperature.
The seedlings can be vulnerable to botrytis (grey mould) if sown too thickly.
White flowers appear en masse in the spring and are followed by white berries in the autumn containing several black seeds.
Collect seed from February to June.
