Woolly Bush Silver Sensation - Adenanthos sericeus 'Silver Sensation'

Adenanthos sericeus 'Silver Sensation' is one of those rare plants that delivers on every level. Touch the foliage and you will immediately understand the appeal, it is extraordinarily soft and silky, with a fine, feathery texture that is unlike almost anything else in the native plant world. The colour is a luminous silver-grey that catches the light beautifully and provides a striking contrast against darker foliage plants, timber, stone, and gravel.

From Spring through Summer and into Autumn, bright orange tubular flowers appear in abundance across the plant, creating a vivid colour combination of silver and orange that is both bold and sophisticated. The flowers are highly attractive to honeyeaters, lorikeets, and other nectar-feeding birds, providing a near year-round food source that brings consistent wildlife activity to the garden.

Slow growing and naturally compact, 'Silver Sensation' reaches 1 to 2m tall and wide and requires minimal maintenance once established. It is highly wind tolerant and adaptable to clay, sandy, and well-drained soils, making it an excellent choice for coastal gardens, mixed borders, and large containers across Melbourne. As a Proteaceae, it requires a low phosphorus fertiliser this is the single most important care requirement for long-term success.

Key Features:

• Soil: Adaptable to clay, sandy, and well-drained soils. More soil-tolerant than many other Proteaceae. Good drainage is still preferred, particularly through Melbourne's wet winters. Avoid soils with high phosphorus content or a history of high phosphorus fertiliser use.
• Light: Full sun to semi-shade. Best silver foliage colour and most prolific orange flowering in full sun. Tolerates semi-shade well, making it one of the more versatile Proteaceae for Melbourne gardens with varied light conditions. Avoid deep shade which reduces both foliage quality and flowering.
• Watering: Water regularly during the first summer of establishment. Once established, water deeply during Melbourne's extended dry periods but allow the soil to dry between waterings. Avoid overwatering in Winter when the plant is less active. Good drainage is important year-round to prevent root issues.
• Fertiliser: Use only a low phosphorus slow-release fertiliser formulated for Proteaceae or Australian natives. Apply sparingly once a year in Spring. Never use standard garden fertilisers, blood and bone, superphosphate, or anything high in phosphorus — as a Proteaceae, 'Silver Sensation' is extremely sensitive to phosphorus and excess can cause rapid decline and death.
• Maintenance: Low. Trim lightly after the main flowering period to maintain a compact, tidy shape and encourage fresh new growth. Avoid cutting into old, leafless wood. Remove any dead or damaged stems as needed. Mulch well year-round, keeping mulch clear of the stem. No significant pest or disease issues under normal Melbourne garden conditions.
• Flowering: Flowers through Spring, Summer, and Autumn, producing bright orange tubular flowers in abundance across the plant for most of the year. The vivid orange flowers against the silver-grey foliage create one of the most striking colour combinations in the native plant world. Flowers are highly attractive to honeyeaters, lorikeets, and other nectar-feeding birds, providing a near year-round food source that brings consistent wildlife activity to the garden.

In the garden, position the plant where it can be touched and appreciated at close range, such as beside a path, gate, or seating area. As with all Proteaceae, the single most important care requirement is avoiding phosphorus, check every fertiliser label before applying and never assume a product is safe without confirming its phosphorus content is very low.
