Aciphylla aurea, commonly known as golden speargrass or golden Spaniard, is a perennial herb native to the alpine and subalpine zones of New Zealand, including both the North and South Islands. It thrives in open grasslands and rocky areas where it is exposed to full sunlight and well-drained soils. This species can reach up to 100 cm (39 in) in height and forms dense clumps of sharp, spiky yellowish-green leaves that contribute to its distinctive appearance. Golden speargrass blooms from January to February, producing a flowerhead that is notably spiky, large, and solid, with yellow or cream-colored flowers that are quite showy despite the plant’s spiny defenses.

Golden speargrass is valued for its unique texture and form, which adds visual interest to rock gardens, alpine collections, and dry landscapes. Its tolerance for low-nutrient soils and resistance to drought make it a low-maintenance choice for gardeners seeking hardy, yet attractive plants. While it is not commonly used for culinary or medicinal purposes, its striking form and coloration make it a conversation piece in cultivation. It is best grown in conditions that mimic its native habitat, with full sun or part shade, low to medium water requirements, and well-drained soils. Gardeners should handle this plant with care due to its sharp foliage. There are no major disease issues, but its spiky leaves can deter some garden visitors, both human and animal.CC BY-SA 4.0
