Bomarea multiflora



Legal Status: Unwanted Organism - BNZ
Status in New Zealand: Established
Organism: Land plants

Other Common name: Climbing alstromeria


The two species of bomarea are similar and are difficult to distinguish. Both are tuberous-rooted vines with thin, pale green, elongated and pointed leaves. They produce trumpet-shaped flowers in dense drooping clusters of 15-20 or more; flowers are tinged red on the outside, and bright yellow with red spots on the inside. Flowering is mainly in the spring or summer. The fruit is a capsule that ripens and splits to reveal bright orange/red fleshy seeds.


If uncontrolled, bomarea can smother and destroy garden plants. It also invades remnant forest and shrubland interiors, with the vines growing into the tree canopy forming large masses which overtop and smother the supporting trees. Extensive infestation in the tree canopy can alter light levels, damage trees and prevent the establishment of native species.
