Ageratum houstonianum
Native to Mexico, Central America and the Caribbean.
A pretty, annual bedding plant that grows in clumps or mounds. It has hairy, rough, oval shaped leaves and produces distinctive, fluffy flower heads that are made up of fine filaments and bloom all summer long.
Regarded as an environmental weed in Queensland and here in New South Wales - so I was surprised to see these planted by council in a public park.

"Ageratum houstonianum" syn. "Ageratum mexicanum" Hort. is a cool-season annual plant often grown as bedding in gardens. The plant grows to 0.3–1 m high, with ovate to triangular leaves 2–7 cm long, and blue flowers. The flower heads are borne in dense corymbs. The ray flowers are threadlike, leading to the common name.
