Family: Gesneriaceae

Origin, Description & Uses
Episcia cupreata, commonly known as flame violet, is a small tropical perennial in the African violet family native to parts of Central and South America, particularly Colombia, Venezuela, and Brazil. This attractive plant is widely grown as an ornamental houseplant and groundcover because of its colorful foliage and bright flowers. Its velvety leaves often display striking patterns in shades of green, bronze, or copper, while the plant produces vivid tubular flowers that are typically red, orange, or scarlet. Flame violet spreads by runners, forming low mats that make it popular for hanging baskets, terrariums, shaded garden beds, and indoor container plantings.

Risks & Threats
Flame violet is considered a low-risk species and is not known to pose significant ecological threats. Although it can spread locally by creeping runners, it generally remains confined to cultivated settings and does not aggressively invade natural areas. In Hawai‘i’s climate it may persist where planted, but there is little evidence that it spreads widely or displaces native vegetation. With responsible planting and basic garden care, flame violet can be enjoyed as a decorative ornamental without posing notable risks to tropical island ecosystems.

High Risk Traits:

• Naturalized elsewhere: Documented as naturalized in Palau.
  
• Shade-tolerant: Thrives in part to full shade, aiding forest understory invasion.
  
• Spreading habit: Creeping, stoloniferous growth can smother low plants.
  
• Vegetative spread: Primarily reproduces via stolons (runners).
  
• Ornamental use: Widely cultivated, increasing introduction risk.
  
• Bird-dispersed seeds: Adapted for bird (and possibly mammal) dispersal.
  
• Gut-resistant seeds: Seeds survive passage through animal guts.

Low Risk Traits:

• Not a pest weed: No evidence of significant agricultural or environmental impacts.
  
• Climate-limited: Strictly tropical; killed by frost (USDA Zones 10-12 only).
  
• Non-toxic: Safe for animals and humans.
  
• No fire risk: Unlikely to increase fire hazard.
  
• Soil-specific: Requires fertile, humus-rich, well-drained soil with narrow pH range.
  
• Pollinator-dependent: Self-incompatible; needs cross-pollination.
  
• Low seed set: Seeds infrequently produced in cultivation.
  
• Poor dispersal mechanisms: Not adapted for wind, water, or external animal transport.
