Blue Haze New Zealand Burr

Blue Haze New Zealand Burr (Acaena saccaticupula 'Blue Haze') is a dreamy, low-growing groundcover prized for its soft blue-gray foliage and vigorous spreading habit. Delicate, pinnate leaves in silvery steel-blue create a misty carpet effect reminiscent of early-morning haze clinging to a hillside. In summer, attractive reddish-brown globose burs rise above the mat on upright stems, adding warmth and texture that contrasts beautifully with the cool blue foliage below.

Developed from Professional Grade root systems, Blue Haze Acaena performs reliably as a weed-suppressing groundcover in rock gardens, between paving stones, along retaining walls, and cascading over raised bed edges. Its cool, muted tones pair elegantly with lavender, ornamental grasses, and purple-toned companions. Highly drought-tolerant once established, it thrives in fast-draining soil and handles lean growing conditions with ease.

Why You'll Love It

• Cool Blue-Gray Foliage: Soft steel-blue pinnate leaves create a misty, ethereal groundcover effect that cools down hot planting schemes and pairs beautifully with purple and silver companions.
• Vigorous Spreading Habit: Spreads quickly and densely to fill gaps, suppress weeds, and soften hard edges along paths, walls, and rocky outcrops.
• Ornamental Bur Interest: Warm reddish-brown globose seed heads emerge in summer and persist into fall, adding textural contrast against the cool blue foliage mat.
• Drought-Smart & Water-Wise: Exceptional drought tolerance once established makes it an ideal choice for xeriscaping, dry gardens, and low-water landscape designs.
• Year-Round Evergreen Presence: Retains its blue-gray foliage through mild winters, maintaining visual interest and groundcover function across all seasons.

These 4" healthy live plants thrive in full sun to light shade in fast-draining, low-fertility soil — excellent drainage is essential to prevent crown rot. Water regularly until established, then reduce to minimal supplemental irrigation. Best suited for USDA Hardiness Zones 6–9. Mature height: 3–6 inches; spread: 18–36 inches. Red-tinged burs appear in summer. Trim lightly in early spring to rejuvenate foliage and encourage fresh growth.
