Alectryon excelsus, commonly known as titoki is a shiny-leaved tree native to New Zealand, where it occurs in coastal and lowland forests. It is a sub-canopy tree growing to 9m in height with a twisting trunk, smooth dark bark, spreading branches and pinnate leaves.
This tree likes to grow in the places that have a lot of water such as wetlands. Titoki tree gravitates towards moist soil which contains many nutrients for growth along with fertile alluvial and sandy soils. The location best suited for this tree are ‘fertile, well-drained soils along riverbanks and associated terraces’.  The plant can grow in conditions from semi-shade to full sun. 
Alectryon excelsus produces small purple flowers in spring and the seeds take up to a year to mature. The colourful seed is initially contained in a hairy woody capsule which splits revealing bright red and black unpalatable fruit (the black portion being the seed). The fruit of this tree is usually eaten by the tui, kererū and kōkako. The fruit is a favourite food of the New Zealand wood pigeon.
