PLANT PROFILE

Callistemon sieberi, commonly known as the River Bottlebrush, is a resilient Australian native shrub known for its soft-textured, linear foliage and pale yellow to creamy-white bottlebrush flowers. These eye-catching blooms appear in spring and attract birds and pollinators, adding biodiversity to the garden.

They look excellent when planted along waterways, in native gardens, or used as informal screens. Callistemon sieberithrives in full sun to part shade, tolerates frost and occasional waterlogging, and adapts well to both moist and drier conditions with minimal maintenance.

Mature Width: 3m – 5m

Approx. 30 – 60 cm per year

Hedging & Screening: Plant 1 m apart for a dense hedge.

Feature Tree: Plant 1.5 m – 2.5 m apart to allow for natural shaping.

Avenue Planting Trees: Not typically used.

How to Plant Callistemon sieberi

  1. Site Selection: Opt for a spot with well-drained soil, although it tolerates wet conditions.
  2. Soil Preparation: Enrich soil with organic compost for better growth.
  3. Hole Digging: Dig a hole roughly twice the size of the root ball.
  4. Planting: Position the Callistemon in the hole, ensuring it's level, backfill with soil, and water generously.

Use this as a reference when digging your planting hole. We recommend digging at least 10% wider than the dimensions below to encourage strong root development.
