Montanoa hibiscifolia, the tree daisy or Anzac-flower, is a species of flowering plant in the family Asteraceae.[2] It is native to Central America and southern Mexico, and it has been introduced to other locations including South Africa and Australia.[1] An erect tree-like perennial reaching 6 m (20 ft), it is invasive, capable of forming dense stands.[2][3]
Inflorescences

It is an erect, tree-like, perennial shrub that is 2 to 7 m (7 to 23 ft) tall.[2][3] Leaf arrangement is simple and their form is opposite. They are pinnatifid when young, and palmately lobed during maturity. The leaves are up to 25 cm (10 in) in length and width, dark green above and paler below, and smoothly hairy on both surfaces, with a pair of lobes at the base of the leaf blade.[4]
Daisy-like flowers, which appear from late autumn to winter, are approximately 4 cm (2 in) across. The ray petals or florets are white in color with a yellow disc. The flowers appear abundantly in terminal branched inflorescences. The disc florets are green but turn yellow. Reddish-brown dry fruits appear like old chartaceous flower heads, one-seeded, which do not open to release the seed.[4][5]
