Have you seen this weed? Bluebell Creeper

Bluebell Creeper (Sollya, Billiadiera heterophylla) is an extremely invasive weed in woodlands and forests. The climber smothers native plants, out-competing them for sunlight and strangling them with their twining stems. Bluebell creeper also contains toxins that can irritate the skin and cause nausea.

GWLAP and the Prospect Hill Bushland Group have been working to tackle this dangerous weed in the Prospect Hill area. Both groups see this weed as a real threat to the important vegetation communities and threatened species that live in the area.

Bluebell Creeper is a twisting, evergreen shrub or climber growing to a height of 3-5 m. The leaves are 3-5 cm long, shiny and oval shaped. Flowers form small clusters of mainly blue bell shaped florets but sometimes can be pink or white. Fruit is small and fleshy, oval-shaped and up to 2cm long. They begin green and ripen to blue-purple in summer and autumn. Each fruit contains more than 50 seeds. Roots are wide spreading and shallow.

The creeper tolerates partial shade and full sun. It can also survive extended dry periods. Seeds are dispersed by birds and possibly possums and ants.

It is important to properly identify bluebell creeper before controlling this weed as it can be confused with a local native species Billiadiera cymosa (Sweet Apple Berry). Once identified, the weed can be controlled through:

  • Pulling or digging out seedlings and saplings.
  • Cutting/scraping stem and swabbing with herbicide.
  • Spraying with a broad-leaf or non-selective herbicide.
