ABOUT
Olearia stellulata, commonly known as the Woolly Daisy Bush, is a visually appealing plant that showcases a variety of interesting features. It has a sturdy and robust growth habit, forming a dense structure. The leaves of this plant are particularly distinctive - they have a leathery texture and are spoon-shaped, giving them a somewhat curled appearance. The upper side of the leaves exhibits a dark green color, contributing to the lush appearance of the plant, while the underside is a contrasting white or silver due to a dense layer of fine, hair-like structures. During its blooming season, the Woolly Daisy Bush produces a profusion of charming flowers. These flowers are small and daisy-like, hence the name, with each flower head consisting of a center made up of tiny tubular florets and an outer ring of petal-like rays. Typically, the flowers exhibit a soft, creamy-white color, which stands out pleasantly against the dark green foliage. The textured surface of the leaves and the downy nature of the stems add to the overall tactile appeal of the plant. When in flower, the bush provides a visually soft and inviting look that can brighten up any garden setting. The Woolly Daisy Bush is also known for its adaptability to various conditions, which, along with its attractive appearance, makes it a favored choice for ornamental planting in the appropriate regions.

WaterThe Snowy Daisy-bush (Olearia stellulata) should be watered thoroughly, allowing water to reach the roots, and then allowed to dry out slightly between waterings to avoid waterlogging. In general, watering once a week is a good rule of thumb, but this can vary depending on the climate and soil conditions. Each watering session should provide enough water to soak the root zone, which could roughly be around 1-2 gallons depending on the size and maturity of the plant. During particularly hot or dry periods, the frequency may need to be increased.
LightSnowy Daisy-bush (Olearia stellulata) prefers full sun to partial shade conditions. The best spot for this plant would be a location where it can receive at least 6 hours of direct sunlight per day. However, in extremely hot climates, some afternoon shade can help protect the plant from scorching.
TemperatureThe Snowy Daisy-bush (Olearia stellulata) can typically handle a wide range of temperatures but performs best in temperate climates. They can survive minimum temperatures down to about 20 degrees Fahrenheit, while the ideal temperature conditions for growth are between 60 to 75 degrees Fahrenheit. Extreme heat or cold beyond these ranges could harm the plant.
PruningPruning the Snowy Daisy-bush (Olearia stellulata) is important to maintain its shape, remove any dead or damaged branches, and encourage new growth. It should be pruned in late winter or early spring before new growth starts. Typically, pruning once a year is adequate, and it's best to prune lightly to avoid shocking the plant.
CleaningAs needed
SoilThe Dusty Daisy Bush prefers well-drained soil with organic matter. Aim for a slightly acidic to neutral pH, around 6.0 to 7.0. A standard potting mix with added compost and perlite will support healthy growth.
RepottingDusty Daisy Bush should be repotted every two to three years or when rootbound. Use the opportunity to refresh the soil mix to ensure continued nutrient availability and good drainage.
Humidity & MistingDusty Daisy Bush tolerates a range of humidity levels but thrives best in moderate conditions. Aim for around 40-60% relative humidity for optimal growth.
Suitable locationsIndoor
Provide bright light and well-draining soil for Dusty Daisy Bush.

Life cycleThe life cycle of the Snowy Daisy-bush (Olearia stellulata) begins with seed germination, which requires a suitable environment with adequate moisture, light, and temperature. The seedlings emerge and grow into juvenile plants, developing a foliage of thick, waxy leaves that are adapted to alpine conditions. As the plant matures, it enters the vegetative stage, forming a bushy structure with sturdy stems. It then reaches reproductive maturity and produces flower heads composed of many small, white blooms that are attractive to pollinators. After pollination, the flowers develop into small, dry fruits which contain seeds that are dispersed by wind or wildlife to begin a new cycle. This perennial shrub may also spread vegetatively through its root system.
PropogationPropogation time
Spring-summer
The Olearia stellulata, commonly known as Dusty Daisy Bush, is typically propagated using semi-hardwood cuttings. This method is most effective when undertaken in late summer or early fall. To propagate, cuttings of about 4 to 6 inches (10 to 15 cm) long should be taken from healthy, disease-free plants. Leaves on the lower half of the cutting should be removed, and the cut end can be dipped in rooting hormone powder to encourage root growth. The prepared cuttings should then be inserted into a pot filled with a mix of peat and coarse sand or a well-draining propagating medium, and kept moist but not waterlogged. To ensure a humid environment, the pot can be covered with a plastic bag or placed in a greenhouse. Cuttings generally root within a few weeks, after which they can be gradually acclimatized to less humid conditions and eventually planted out.
