This pest alert is a pleasant-looking plant species whose name and appearance almost evoke a Sunday cuppa with the vicar.
Cathedral Bells (Cobaea scandens) is a fast-growing, evergreen climbing vine that can grow six metres tall and cover trees and shrubs in forests, roadsides, riverbanks, gardens, hedges, shelter belts and open areas.
It was introduced to New Zealand for its ornamental qualities and was historically planted around homesteads for its attractive bell-like purplish flowers.
The shape of the flowers has previously led to it also being called the “Cup and Saucer” plant.
Flowering occurs between February and April, followed by the emergence of seed pods – hard, oval capsules around 5 – 8 cm long which are full of winged seeds and spread into the immediate surroundings.
These seeds germinate and a clag of thick smothering vines eventuate. This is where the pesty properties come to the fore.
This pest vine is listed in the Tasman Nelson Pest Management Plan as an eradication species. It is currently known to be active at three locations in Golden Bay and an infestation in Dodson’s Valley, Nelson.
