Woolly Bush Silver Streak

Adenanthos sericeus Silver Streak

The Silver Woolly Bush (Silver Streak) is a stunning, upright shrub-like native tree with beautiful silky, silver foliage.

Adenanthos sericeus ‘Silver Streak’ is a cultivar of the species Adenanthos sericeus, commonly known as the woolly bush or silver bush. This evergreen shrub is native to the coastal regions of Western Australia and is valued for its striking silvery foliage and unique growth habit. The ‘Silver Streak’ variety is a compact, ornamental cultivar that is particularly appreciated for its eye-catching appearance and adaptability in gardens, especially in arid or coastal conditions.

Key Features:

  1. Foliage:
    • The most notable feature of Adenanthos sericeus ‘Silver Streak’ is its dense, silvery-grey foliage, which is covered with fine, woolly hairs that give it a soft, velvety texture. This gives the plant a silvery or almost metallic appearance, especially when viewed in bright light.
    • The narrow, linear leaves are arranged in a way that contributes to the bush’s delicate and fine texture.
  2. Size and Growth Habit:
    • ‘Silver Streak’ is a relatively compact cultivar, typically growing to about 1.5–2 meters (5–6.5 feet) in height and 1–1.5 meters (3–5 feet) in width, though its size may vary slightly depending on growing conditions.
    • It has an upright, bushy growth habit with dense branching, making it an excellent choice for hedging or as a focal point in garden landscapes.
  3. Flowers:
    • Like other Adenanthos species, ‘Silver Streak’ produces small, tubular flowers that are typically red or orange in color. These flowers are attractive to pollinators, especially birds and bees.
    • Flowering typically occurs during the spring to summer months, though this can vary depending on climate and growing conditions.
  4. Growth Rate:
    • Adenanthos sericeus ‘Silver Streak’ is considered a relatively fast-growing shrub, especially in its first few years, when it can quickly reach its mature size.
  5. Hardiness and Care:
    • Climate: It is well-suited to Mediterranean climates, where winters are mild and summers are dry.
    • Soil: Prefers well-drained soils, especially sandy or loamy soils, and is moderately tolerant of poor soils, as long as drainage is adequate. It does not tolerate waterlogged conditions.
    • Sunlight: Thrives in full sun to part shade, with full sun leading to the best silvering of the foliage.
    • Watering: Once established, it is relatively drought-tolerant, but it should be watered regularly during its initial growth phase.
    • Fertilization: It benefits from low-phosphorus fertilizers, as high phosphorus can harm plants from the Proteaceae family to which Adenanthos belongs.
  6. Pests and Diseases:
    • Adenanthos sericeus cultivars are generally resistant to pests, but like many Australian natives, they can be prone to root rot in poorly drained soils. It’s important to ensure the plant is not waterlogged.
    • It can also be susceptible to fungal diseases in humid environments, though this is less common.

Landscape Uses:

  • Ornamental Shrub: Due to its striking foliage and attractive flowers, Adenanthos sericeus ‘Silver Streak’ is a popular choice for ornamental gardens, especially in coastal, dry, or Mediterranean landscapes.
  • Hedges and Screens: Its dense growth habit and compact size make it an ideal candidate for low to medium-height hedging or privacy screens.
  • Pollinator Gardens: The plant is a good addition to gardens designed to attract pollinators, as its flowers draw birds and bees.
  • Rock Gardens: It is well-suited for rockeries or dry gardens, thanks to its tolerance of poor, well-drained soils.

General Care Tips:

  • Ensure the plant is located in a sunny spot with well-drained soil.
  • Water moderately during the growing season, allowing the soil to dry out between watering.
  • Prune occasionally to maintain a tidy shape and promote bushier growth.
  • If growing in a container, ensure the pot has excellent drainage and use a well-draining, sandy potting mix.
