What does it look like?
Buddleia is a woody and deciduous ornamental shrub that grows up to 3m tall. The small mauve/purple flowers are orange inside and form distinctive cone-shaped hanging clusters between December and February, followed by seed capsules 5-10mm long.
The plant invades river beds, streamsides, disturbed areas, shrubland and forest margins. It tolerates a wide range of soils and temperatures, prefers wet to moderately dry conditions and is resistant to wind and damage. It can grow in shade or open areas, but seedlings require high light levels.
Why is it a problem?
Buddleia establishes and grows quickly, forming dense thickets in a wide range of habitats, excluding other plants. It reproduces vegetatively through regeneration from suckers, as well as producing vast numbers of highly viable seeds. All of these factors make it very successful in out-competing other native species.
- Hand pull or dig out small plants and leave on site to rot down.

- Glyphosate 250ml per 10L water;
- Tordon Brushkiller 250ml per 10L water.
Spray February-April with:
- Glyphosate 10ml per 1L water;
- Metsulfuron-methyl (600g/kg) 5g per 10L water;
Tordon Brushkiller 90ml per 15L water;
- Young plants can be sprayed late summer to autumn with glyphosate 10ml per 1L water;
- Young plants can be sprayed late summer to autumn with metsulfuron-methyl 5g per 10L water.
