Species of plant
Gastrolobium grandiflorum, commonly known as wallflower poison, wallflower poison bush or heart-leaf poison bush, is a bushy shrub which is endemic to Australia.
It grows to 2 or 3 metres in height and between late summer and early winter (February to August in Australia) it produces orange-red pea-flowers with a yellow centre and red veins. The leaves are hairy and heart-shaped on younger plants and elliptic and more glabrous on older plants, up to 6 cm long and 2.7 cm wide.
The species was first formally described by botanist Ferdinand von Mueller and published in Fragmenta Phytographiae Australiae in 1863. It is the most widespread within the genus, occurring across a large area of Queensland, as well as in the Northern Territory, Western Australia and South Australia.
