blue goose leaf


The plant known as Bidgee-widgee is a visually interesting species with a distinctive appearance. It features a mat of fine, feathery foliage that often presents itself in lush green color. This foliage creates a dense and textured carpet that is both soft to the touch and appealing to the eye. The leaves are small, pinnate, and typically have a slightly serrated edge, contributing to the delicate and intricate look of the plant. A standout feature of Bidgee-widgee is its unique seed heads or burrs that appear after the flowering season. These seed heads are typically rounded with spines or hooks, which can easily latch onto passing animals or clothing, allowing the plant to disperse its seeds over a larger area. The flowers of the Bidgee-widgee are generally inconspicuous and do not contribute significantly to its ornamental value. However, these flowers precede the burrs and are integral to the plant's reproductive cycle. The overall aesthetic of the Bidgee-widgee is one that may be suited for rock gardens or as a low ground cover due to its mat-forming habit. This plant can provide an interesting texture and foliage contrast when paired with other garden plants. Its prostrate nature and tendency to spread can create a cohesive look in landscape designs, making it a fascinating and practical choice for gardeners looking for low-growing vegetation.

    For the "Blue Haze" Pirri-pirri bur, it's important to provide consistent moisture without over-saturating the soil. Water the plant thoroughly, allowing water to soak in rather than run off. Aim to water every week, supplying about 1 to 2 gallons per square foot of soil, depending on the climate and weather conditions. During periods of extreme heat or dryness, watering frequency may need to increase to maintain soil moisture. However, ensure that the plant isn't left standing in water as this could lead to root rot.

  • sunLight

    Blue Haze Pirri-pirri bur thrives in full sun to partial shade conditions. The best spot is one where the plant can receive at least 6 hours of sunlight per day. When placing the plant indoors, a south-facing or west-facing window would be ideal to provide the necessary light, but avoid intense, direct sunlight during the hottest part of the day.

  • thermometerTemperature

    The Blue Haze Pirri-pirri bur performs best in temperate climates with temperatures ranging from 50°F to 75°F. It can withstand short periods of temperature drops to 20°F and highs up to 90°F. However, for optimal growth, aim to maintain a comfortable temperature close to the 70°F mark. The plant may need protection if temperatures are expected to remain below the minimum threshold for extended periods.

  • scissorsPruning

    Pruning Blue Haze Pirri-pirri bur is mainly for aesthetic purposes and to control its spread, as it can be quite vigorous. Prune in late winter or early spring to remove dead or damaged foliage and to shape the plant. Cutting back the plant every year or as needed can encourage more compact, dense growth. The best time to prune is just before new growth starts in spring.

    The common name for Acaena saccaticupula is Buzzy Blue. The best soil mix for Buzzy Blue is well-draining with a combination of loam, peat, and coarse sand or perlite. The soil should have a pH around 6.0 to 7.0, slightly acidic to neutral. Additionally, incorporating organic matter can help with nutrient retention and soil structure.

  • plantRepotting

    Buzzy Blue, commonly known as Acaena saccaticupula, should be repotted every 1-2 years to refresh the soil and allow for continued growth. Repot in spring or early summer before new growth begins, using a slightly larger pot to accommodate the plant's spreading habit.

  • circleLife cycle

    Acaena saccaticupula, commonly known as Blue Haze, begins its life cycle as a seed which germinates in late winter to early spring, given adequate moisture and light conditions. Upon germination, the seedling develops a root system and a rosette of leaves close to the ground, characteristic of this low-growing perennial. As the plant matures, it produces more leaves and stems, spreading outwards to form a mat-like ground cover. By late spring to early summer, Blue Haze produces small, inconspicuous flowers that, if pollinated, develop into burr-like seed heads that give the plant its distinct appearance. These seed heads can attach to animals or be dispersed by wind, aiding in the spread of the seeds to initiate new growth elsewhere. Throughout the year, but especially in autumn, older parts of the plant may die back, while new growth continues from the center of the rosette or from stolons extending from the main plant.

    • The most popular method for propagating Acaena saccaticupula, commonly known as Blue Haze, is by division. This is typically done in the spring or fall when the plant's growth is most active. To propagate by division, carefully dig up the plant and gently separate the root ball into smaller sections, ensuring that each new section has a good root system and several shoots. These divisions can then be replanted in well-draining soil, spaced about 6 to 12 inches (approximately 15 to 30 centimeters) apart to allow for growth. Water the new plantings thoroughly after planting to help establish the roots. Division is a straightforward and effective way to create new Blue Haze plants and to maintain the health and vigor of the original plant by reducing overcrowding.
