About

Acaena buchananii is a fast-growing evergreen perennial that forms a dense mat of finely divided blue-green leaves. It produces clusters of white flowers on upright stems that gradually develop a reddish hue as they mature. This plant serves well as ground cover in flower beds, rock gardens, along paths, and against dry stone walls.

About the genus

Acaena comprises evergreen perennials or subshrubs characterized by pinnate foliage featuring serrated leaflets. The small flowers are borne in compact, rounded clusters or spikes, which subsequently give rise to distinctive burr-like fruiting structures.
