About Tetragonia implexicoma (Miq.) Hook.fil.
Commonly known as bower spinach, this species has the scientific name Tetragonia implexicoma (Miq.) Hook.fil. It is a scrambling subshrub that forms dense, leafy patches that can reach up to 4 metres (13 ft) across. Its stems are long and trailing, often succulent; young stems are coloured red or pink, while mature stems darken to dark green, brown, or black and become woody. Its leaves grow in an alternate arrangement, are clustered and semi-succulent, and range in shape from rhombic to angular-ovate. Young leaves sometimes bear coarse hairs. Bower spinach produces solitary, strongly scented yellow flowers, which have 12 to 20 stamens and 2 styles. Its flowering period runs from August to November. The fruits are 5–8 millimetres (0.20–0.31 in) long, pink to dark red, succulent berries, which are eaten by birds and lizards. This species is currently planted on Phillip Island for use as a fire retardant plant. Bower spinach occurs mainly in coastal regions of New Zealand and southern Australia, as well as on many nearby island groups. It grows in a wide variety of habitats, including sand and shingle beaches, coastal woodland, coastal shrubland, coastal grassland, and exposed, salt-pruned vegetation on cliffs and stacks. It can also be found growing well inland: in farmland where it is grown in barberry hedges, and on calcareous sandstone or limestone outcrops within dense forest.
