Summary

Acaena novae-zelandiae, commonly known as Red Bidibid, is an evergreen perennial herb native to grasslands, alpine regions, and coastal scrublands in New Zealand, New Guinea, and Australia. It forms a low-growing mat reaching a height of about 0.3 feet (10 cm) and can spread widely to cover an area of 3 feet (1 meter). The plant features small, finely divided leaves that can take on a reddish tint in full sun, adding to its ornamental value. During the summer and fall, Red Bidibid produces inconspicuous green flowers that mature into burr-like seed heads with reddish-purple hues, which can be quite showy.

Red Bidibid is valued for its ability to form dense ground covers, which can help to suppress weeds and stabilize soil. It is suitable for rock gardens, alpine gardens, and as a filler between stepping stones due to its low stature and spreading habit. This plant is drought-tolerant once established, requiring minimal water and thriving in well-drained soils. It can adapt to a range of light conditions from full sun, where its foliage color intensifies, to part shade. However, gardeners should be cautious as Acaena novae-zelandiae can become invasive outside its native range, particularly in areas like California and Hawaii, where it can outcompete native species.CC BY-SA 4.0
