Family: Myrtaceae

Melaleuca hislopii, also known as silky net-bush or woolly net-bush, is a small tree or large shrub native to Western Australia. Formerly known as Calothamnus villosus, it is recognized for its narrow, needle-like foliage and distinctive one-sided flower clusters. The flowers are typically bright red, with long, prominent stamens that give them a soft, brush-like appearance. These striking blooms make the plant an attractive ornamental, and it is sometimes used in landscaping for screening or as a feature plant in dry, sunny gardens. Once established, it is tolerant of drought and poor soils.

There is currently little evidence that Melaleuca hislopii poses significant environmental risks. It has not been documented as invasive, and its spread beyond cultivation appears limited. However, as with any introduced species, especially those adapted to dry conditions, planting near natural areas should be done with care. Monitoring for unexpected spread is recommended to ensure it does not displace native plants or alter local ecosystems over time.

High Risk Traits:

• Other species in the genus have become invasive
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• Seeds retained on plant; intentionally dispersed by people and possibly by wind or water
  
• Able to resprout after cutting, hard pruning and fire
  
• Gaps in biological and ecological information may limit accuracy of risk prediction

Low Risk Traits:

• No reports of invasiveness or naturalization or invasiveness, but limited evidence of widespread introduction outside native range
  
• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic
  
• Not reported to spread vegetatively
  
• Seeds remain on plant (may limit ability to spread)
