Homalanthus populifolius, the bleeding heart, native poplar or Queensland poplar, is an Australian rainforest plant in the family Euphorbiaceae. It often appears in areas of rainforest disturbance. Bleeding heart is highly regarded by rainforest regenerators because of its fast growth and use as a pioneer species in rainforest regeneration.
Bleeding heart grows from the coastal border of New South Wales and Victoria (36° S), north to Coen, Queensland (13° S) in the tropics. It is also native to Lord Howe Island, Norfolk Island, Papua New Guinea and Solomon Islands, and has been widely planted elsewhere.[1]
It is the host plant for Australia's largest moth, the Hercules moth (Coscinocera hercules).
It is a small tree or shrub, up to 8 meters tall and 15 cm in diameter.
The trunk is cylindrical with greyish-brown bark, fairly smooth but with some bumps and irregularities. Branchlets appear thick, reddish or green. The leaves are triangular, not toothed and alternate, 5 to 15 cm long, and like those of a poplar (giving rise to the species epithet populifolius). The leaves turn red when senescent, hence the common name of bleeding heart.
Flowers are yellow green to red, 2 to 10 cm long. Appearing on racemes mostly in the months of September to December. The fruit matures from December to March, being a two-lobed capsule with an oily yellow aril. The seeds germinate quickly when the warmth of direct sunlight is available. However, as with many pioneer species, the seeds of the bleeding heart have a long dormancy period.
The fruit is eaten by a variety of birds, including brown cuckoo dove, silvereye and Lewin's honeyeater.
The small size and decorative red leaves make this an attractive garden plant. However, its characteristics as a pioneer species also make it a good invader in disturbed areas. It is regarded as an invasive species in southern Africa,[2] Hawaii[3] and New Zealand. The Sa’dan Toraja people crush the leaves with mud to create a black dye for funeral clothing

Omalanthus populifolius, Corazón sangrante (Bleeding Heart) o Álamo de Queensland es una planta de las selvas templadas y subtropicales lluviosas de Australia. Con frecuencia aparece en áreas disturbadas del bosque. El corazón sangrante es apreciado por los regeneradores del bosque por su rápido crecimiento y por ser una de las especies pioneras en la rgeneración del bosque.
El corazón sangrante crece desde la frontera costera de Nueva Gales del Sur y Victoria (36° S), al norte hasta Coen, Queensland (13° S) en el trópico. Se le encuentra también en la Isla Lord Howe, Isla Norfolk , Nueva Guinea e Indonesia, y ha sido ampliamente plantado en otras partes.
Es un pequeño árbol o arbusto, de hasta 8 metros de alto y 15 cm de diámetro.
El tronco es cilíndrico con la corteza café grisácea, bastante lisa pero con algunas protuberancias e irregularidades. Las ramillas son lisas, rojizas o verdes. Las hojas son triangulares, no son dentadas y son alternadas. De 5 a 15 cm de largo. Las hojas se tornan rojas cuando senescentes, por lo tanto el nombre común de corazón sangrante.
Las flores son amarillas verdosas a rojas, de 2 a 10 cm de largo. Apareciendo en racimos en su mayor parte entre los meses de septiembre a enero. El fruto madura desde diciembre a marzo, siendo una cápsula de dos lóbulos con un arilo amarillo aceitoso. Las semillas germinan rápidamente si se presenta el calor de la luz solar. Sin embargo, como muchas de las especies pioneras, las semillas del corazón sangrante necesitan un largo período de dormancia.
El fruto es comido por una variedad de aves, incluyendo la paloma cuco parda, ojo de plata y melífago de Lewin.
La talla pequeña y las hojas rojas decorativas lo hacen una atractiva planta de jardín. Sin embargo, sus características como planta pionera lo convierten en un buen invasor en áreas disturbadas. Es considerada como una planta invasora en el sur de África[1] y Hawái.[2]
Homalanthus populifolius fue descrita por Robert Graham y publicado en Edinburgh New Philosophical Journal 3: 175. 1827.[3]
