Family: Asteraceae

Origin, Description & Uses:
Layia platyglossa, commonly known as tidy tips, is a cheerful annual wildflower native to coastal and inland regions from California to Baja California, Mexico. It is easily recognized by its bright yellow daisy-like flowers tipped with distinctive white edges, giving it a neat, “tidy” appearance. This low-growing plant thrives in open, sunny areas and well-drained soils, and it is often included in wildflower mixes, roadside plantings, and pollinator gardens. Tidy tips are valued for their ability to attract bees, butterflies, and other beneficial insects, making them a popular choice for supporting biodiversity in ornamental and restoration plantings.

Risks & Threats:
Tidy tips is considered a low-risk species and is not known to be invasive or naturalized in Hawaiʻi. It generally remains where it is planted and does not aggressively spread or outcompete other vegetation. While it produces seeds that allow it to reappear in subsequent seasons, its growth habit is not typically associated with ecological disruption. As with any introduced species, responsible planting and monitoring are recommended, but current evidence suggests that Layia platyglossa poses little to no threat to native ecosystems or agriculture in Hawaiʻi.

High Risk Traits:

• Elevation range exceeds 1000 m, and can grow in >5 hardiness zones demonstrating environmental versatility
  
• Possibly naturalized in Massachusetts (or a cultivation escape)
  
• Tolerates many soil types
  
• Seeds dispersed by wind, possibly externally on animals and intentionally by people
  
• Able to reach maturity in <1 year (annual)
  
• Limited or missing ecological information makes accurate risk prediction difficult

Low Risk Traits:

• No documented negative impacts to date
  
• If able to naturalize, may only pose a threat to higher elevation areas in the tropics
  
• Unarmed (no spines, thorns or burrs)
  
• No reports of toxicity or allergens
  
• Beneficial to bees and other pollinators
  
• Ornamental
  
• Not known to form dense stands
  
• Not reported to spread vegetatively
