Bomarea invades remnant forest and shrubland interiors. The vines grow into the tree canopy and form large masses, which overtop and smother the supporting trees.

Seedlings can establish in the shade of forest interior, creeping along the ground, strangling saplings and smothering low growing species. Extensive infestations in the tree canopy alter light levels, which can kill mature trees and prevent the establishment of native species. If left uncontrolled bomarea can smother and eventually destroy favourite plants in your garden.

Bomarea's leaves are thin, pale green, elongated and pointed. Trumpet shaped flowers are produced in dense drooping clusters of 15-20 flowers. They are tinged red outside and are bright yellow with red spots on the inside. Flowering can occur at any time but primarily in the summer. The fruit is a capsule that ripens and splits to reveal bright orange/red fleshy seeds, dispersed by birds.

Under ground the plant consists of a long rhizome with roots and tubers (that look like potatoes) attached. The size of the rhizome and tubers varies depending on the age of the plant.

Management and control

Under the Pest Management Plan, land occupiers are required by law to destroy any bomarea on their land.

To prevent the spread of seed, remove all flowers and seeds as they appear. Place seed pods in a black plastic bag, letting the sun cook the contents before disposing of them. Where possible, cut the aerial vines and dig out all the rhizomes. Regrowth can occur from any rhizome fragments left in the soil.

The use of glyphosate based products such as Turbo 300, G360 or Roundup has been found to be effective at a mixing rate of 2%. Vigilant gel is also very effective when applied to freshly cut vines. It is not recommended that Vigilant is used close to valuable or desirable species.

To protect the host plant from chemical damage, remove the bomarea, place it on the ground and then spray. Alternatively, cut the vines 150mm above ground level and spray or paint the freshly cut stems. (Beware of non-target damage as glyphosate is non-selective).

Use herbicides at application rates recommended by the manufacturer and wear protective clothing.

Control of a pest plant is not a one-off task. Follow up action must regularly be undertaken. The site must be checked for regrowth from underground rhizomes and seedling establishment. Plant a friendly alternative such as native Clematis or Parsonia species.
