Family: Araceae

Origin, Description & Uses
Philodendron bipinnatifidum, commonly known as tree philodendron or selloum, is a large tropical plant native to eastern Bolivia, southeastern and southern Brazil, and northeastern Argentina. This striking ornamental is valued for its dramatic, deeply lobed leaves and lush, tropical appearance. Although often called a “tree philodendron,” it is not a true tree but can develop a thick trunk-like stem as it matures. It is widely grown in tropical and subtropical landscapes, as well as indoors in large containers, where it is appreciated for its bold foliage, adaptability to shade, and low maintenance requirements.

Risks & Threats
Tree philodendron is considered a low risk species for Hawaii. While it may occasionally spread vegetatively in favorable environments, it is not regarded as highly invasive and has not demonstrated widespread harmful impacts on natural ecosystems. In landscapes, large plants can spread outward and may require regular pruning to manage their size. As with many aroids, all parts of the plant contain calcium oxalate crystals and can be irritating or toxic if ingested by people or pets. When planted responsibly and properly maintained, tree philodendron can be a suitable ornamental choice for tropical gardens.

High Risk Traits:

• Thrives in tropical climates
  
• All parts of plant are poisonous, and sap can be a skin irritant
  
• Shade-tolerant
  
• Seeds potentially bird-dispersed
  
• Can resprout if cut to base

Low Risk Traits:

• No confirmed reports of naturalization or invasiveness to date
  
• Unarmed (no spines, thorns or burrs)
  
• Valued as an ornamental
  
• Plants functionally self-incompatible
  
• Requires specialized beetle pollinators
  
• Reaches maturity after 15+ years
  
• Not likely to form a persistent seed bank
  
• Herbicides effectively control this plant
