Family: Apocynaceae

Origin, Description & Uses:
Hoodia officinalis is a succulent plant native to the arid regions of southern Africa, particularly Namibia and South Africa. It grows in dry, desert-like environments and is well adapted to harsh conditions, with thick, fleshy stems that store water and small, spiny ridges for protection. The plant produces distinctive, star-shaped flowers that often have a strong odor to attract pollinators. Traditionally, Hoodia species have been used by Indigenous peoples, such as the San, as an appetite suppressant during long hunting trips. Today, Hoodia officinalis is occasionally cultivated as an ornamental succulent and has also gained attention for its potential use in dietary supplements.

Risks & Threats:
Hoodia officinalis is considered low risk in Hawaii and other tropical regions. It has very specific environmental requirements, preferring hot, dry climates, which limits its ability to spread aggressively in wetter ecosystems. There is no evidence that this species naturalizes or becomes invasive, and it does not pose a significant threat to native plants or habitats. As with many succulents, it is slow-growing and unlikely to outcompete other vegetation. Gardeners should still practice responsible planting and disposal, but overall, this species is not considered a concern for Hawaii’s natural ecosystems.

High Risk Traits:

• Able to grow in regions with tropical climates
  
• Spiny
  
• Reproduces by wind-dispersed seeds (but limited seed production in cultivation)
  
• May be able to produce interspecific and intergeneric hybrids
  
• Limited ecological information may reduce accuracy of risk prediction

Low Risk Traits:

• No reports of invasiveness or naturalization, but introduction outside native range appears to be limited
  
• Valuable medicinal plant
  
• Susceptibility to bacterial and fungal rot, mites and mite transmitted diseases may limit ability to escape and spread in the Hawaiian Islands
  
• Rarely, if ever, produces seed in cultivation
  
• Possibly self-incompatible
  
• Possibly requires specialized pollinators
  
• Not reported to spread vegetatively
