Coastal morning glory

Thought to be native to tropical Africa and Asia, coastal morning glory is a fast-growing vine that can climb 4-5m into the forest canopy and smothers native vegetation. It is becoming common in areas of coastal Queensland, particularly along riverbanks.

Significant infestations of coastal morning glory can destroy native vegetation and displace native animals due to habitat destruction.

Coastal morning glory is not a declared pest under Queensland legislation.
