Family: Oxalidaceae
High Risk Traits:
- Grows in warm temperate to tropical climates
- Naturalized on all the main Hawaiian Islands except Ni'ihau and Kaho'olawe; widely naturalized elsewhere
- Garden and disturbance adapted weed
- Potential crop and environmental weed (impacts generally innocuous)
- Other Oxalis species are invasive
- Potentially allelopathic
- May be toxic to animals and people if consumed in large quantities due to high levels of oxalate
- Shade tolerant
- Persists from bulbs and spreads vegetatively from bulbils
- Bulbils spread in soil, as a pot contaminant, and potentially by people
Low Risk Traits:
- Despite widespread naturalization and weediness, generally not regarded as a significant problem in agricultural or natural areas
- Unarmed (no spines, thorns, or burrs)
- Provides fodder for livestock (palatable despite potential toxicity)
- Limited or no seed production in Hawaiian Islands, and other locations outside native range
- Herbicides may provide effective control
