  • water dropWater

    The New Zealand Bur; water deeply but infrequently to simulate natural conditions, aiming for a deep soak rather than frequent light watering. During the growing season of spring through fall, water once every week or two, ensuring the plant receives roughly one gallon per watering session for an established plant, adjusting for particularly hot or dry conditions which may necessitate a slightly increased frequency. In winter, reduce watering to every two to three weeks, depending on the climate and whether the plant is receiving additional moisture from rain or snowfall. Always allow the soil to dry out partially between waterings to prevent root rot, a common issue with overwatered Acaena.

  • sunLight

    The New Zealand Bur; thrives best in full sun to partial shade. It prefers a location where it can receive at least 4-6 hours of direct sunlight daily. An ideal spot would provide morning sunlight and dappled shade in the afternoon, especially in regions with very hot summers, to protect it from the most intense afternoon rays.

  • thermometerTemperature

    The New Zealand Bur; prefers temperatures in a range of 60 to 75 degrees Fahrenheit but can tolerate temperatures as low as 50 degrees Fahrenheit and as high as 85 degrees Fahrenheit. Its ideal growing conditions are within the moderate climate band, where temperature extremes are rare.

  • scissorsPruning

    The New Zealand Bur; should be pruned to remove dead or damaged foliage, which encourages healthy growth and prevents disease. Prune in late winter or early spring before new growth starts. The plant typically requires little pruning, but cutting back can be done every couple of years to maintain its shape and rejuvenate older plants.

  • circleLife cycle

    Acaena saccaticupula 'Blue Haze', commonly known as Blue Haze New Zealand Bur, begins its life cycle with germination, which tends to occur effectively in moist, well-drained soil and under adequate warmth. The seedlings emerge and establish a rosette of bluish-green, feathery foliage, growing into a dense, ground-covering mat. Throughout the growing season, particularly in summer, it produces flowering stems that rise above the foliage, with small, inconspicuous flowers that can attract pollinators. After pollination, the flowers transform into bur-like seed heads covered in hooks or spines. These burs can be dispersed by animals or humans as they cling to fur or clothing, facilitating the plant's spread. As a perennial, Blue Haze New Zealand Bur will die back in winter, especially in colder climates, before re-sprouting from the root system in the following spring to continue its cycle.

      Spring to early summer

    • Acaena saccaticupula 'Blue Haze', commonly known as New Zealand Bur, is a plant that is often propagated through seed or division. The most popular method of propagation for New Zealand Bur is by division, which is best performed in early spring. To propagate by division, carefully lift the parent plant from the ground and use a sharp knife or spade to divide the root ball into several sections, ensuring each section has a good portion of roots and at least a few shoots. These divisions can then be replanted immediately into well-prepared soil, spaced about 12 inches (approximately 30 centimeters) apart to give the plants plenty of room to spread. Water the new plants thoroughly after planting and maintain even moisture until they are well established.
