The Story
Plant Bio
Callistemon is a genus of evergreen Australian shrubs and trees characterised by woody stems and narrow, leathery foliage. The distinctive inflorescences consist of dense, cylindrical spikes of long, brightly coloured stamens that resemble bottle brushes and attract numerous nectar-feeding birds.
'Kings Park Special' is an upright, dense cultivar growing three to five metres tall with slightly weeping branchlets and shiny, dark-green lanceolate leaves. It is distinguished by multiple terminal heads of bright crimson flower spikes up to 13 centimetres long that appear primarily during spring and summer.

Planting
How to Grow
- Select a site in full sun to part shade with well-drained soil, though heavier clay is tolerated if moisture is managed.
- Dig a hole twice the width of the root ball and of equal depth, placing the plant so the soil level matches the pot level.
- Backfill with local soil, firm down gently to remove air pockets, and water in thoroughly to settle the roots.
- Apply an organic mulch layer around the base, keeping it clear of the main stem to prevent collar rot.
Pro Tip
Prune immediately after the main spring flowering flush to maintain a dense habit; while this cultivar tolerates hard pruning into old wood, routine light pruning prevents the canopy from becoming woody and sparse.

Care Guide
Do
- Prune immediately after the main spring flowering flush to encourage bushy growth.
- Water occasionally during prolonged dry spells to maintain optimal flowering performance.
- Apply a low-phosphorus native fertiliser in spring if growth appears sluggish.
Don't
- Do not prune aggressively multiple times a year unless maintaining a formal screen.
- Do not allow young plants to dry out completely before their root systems are fully established.
- Do not plant in poorly drained, waterlogged hollows where Phytophthora dieback is a risk.
