About
The plant commonly known as *Philodendron bipinnatifidum* is a large, tree-like aroid appreciated for its massive, deeply lobed, deep green foliage. It is notable for its ability to grow into a substantial, woody structure that can spread over a wide area, and its unique reproductive cycle involving heat-producing flowers.
Field notes
Morphology
The leaves are simple, large, and deeply lobed, typically drooping, and can grow up to 1.5 meters long. They are attached to long, smooth petioles and are a deep green color. The trunk is relatively thick and woody, featuring characteristic "eye-drop" leaf scars. The flowers are small and petalless, housed on a spadix within a spathe.
Distribution & habitat
Native to South America, specifically Brazil, Bolivia, Argentina, and Paraguay. It is also cultivated in tropical, subtropical, and warm temperate climates, including the Philippines, Australia, the Gulf Coast and East Coast of the United States, South Africa, and northern New Zealand.
Ecology
Pollination is carried out by beetle species, specifically *Erioscelis* and *Cyclocephala*. The plant's reproductive structure maintains a constant high temperature (34 °C or 93 °F) by metabolizing stored fatty tissue, which is believed to volatilize and disperse insect-attracting odors and stimulate beetle activity.
Cultivation notes
It is cultivated as a landscape plant in many tropical, subtropical, and warm temperate countries. It can also be grown as a houseplant in cool temperate regions. It is best grown in rich, moisture-retentive soil that can be slightly alkaline, but it cannot tolerate high salt concentration.
History & etymology
The names *Philodendron bipinnatifidum* and *Philodendron selloanum* were once accepted as separate species, but recent studies suggest they are multiforms of the same species. The name *Philodendron bipinnatifidum* was accepted as the scientific name because it was the first of the two to be published.
