Acaena saccaticupula 'Blue Haze' is a low-growing, evergreen perennial that reaches a height of approximately 10 cm and can spread up to 1 meter in width. Its foliage consists of 9-15 oval, serrated leaflets that exhibit a blue-grey hue with bronze edges. In midsummer, the plant produces rounded clusters of white flowers on short stems, which later develop into dark red burrs adorned with pinkish-red spines.
