Which plants will be our next weeds?
-
More than 70% of our environmental weeds were originally garden plants that have escaped and spread!
-
Some exotic plants naturalised long ago (e.g., gorse in 1867), while others have naturalised more recently (e.g., spartina in 1981).
-
Some plant species, in New Zealand, such as bangalow palms, phoenix palms and kiwifruit may take up to 100 years before they naturalise (overcome barriers and reproduce) and are therefore often called 'sleepers'. They often spread slowly and go unnoticed until they are widespread.
-
The most widespread weeds in New Zealand were ones that were planted a long time ago (e.g., gorse). Will the palms and pretty trees we plant now be New Zealand's worst weeds in 100 years?
