Family: Marantaceae

Origin, Description & Uses
Stromanthe thalia is native to eastern Brazil, ranging from Bahia to Paraná, where it grows in warm, humid tropical forests. It is a member of the prayer plant family (Marantaceae) and is valued for its striking ornamental foliage, typically featuring broad, oval leaves with bold patterns of green, cream, and sometimes pink or burgundy tones. Like other Stromanthe species, it is widely cultivated as a tropical landscape accent and houseplant, appreciated for its lush, colorful appearance and ability to bring a bold, tropical aesthetic to shaded garden areas or indoor environments.

Risks & Threats
This species is considered low risk in Hawaiʻi and is not known to be naturalized or invasive in the state. It does not currently show traits associated with aggressive spread in local ecosystems, and it is primarily maintained in cultivation rather than escaping into wild areas. As with many tropical ornamentals, continued monitoring is still appropriate in favorable wet, shaded habitats where related species have occasionally shown limited persistence, but overall Stromanthe thalia is regarded as a safe, well-behaved landscape and container plant option.

High Risk Traits:

• Thrives in tropical climates
  
• Other Stromanthe species have become naturalized and are potential weeds
  
• Shade-tolerant
  
• Tolerates many soil types
  
• Reproduces by seeds and vegetatively by rhizomes
  
• Seeds dispersed by birds and intentionally by people
  
• Able to resprout from rhizomes after cutting

Low Risk Traits:

• No reports of invasiveness or naturalization
  
• Unarmed (no spines, thorns, or burrs)
  
• Bird-pollination requirement may limit seed set in introduced range
