Learn About Your New Callistemon citrinus 'Harkness' – Harkness Bottlebrush

Callistemon citrinus 'Harkness' is a compact, evergreen Australian native shrub known for its dense growth habit and vivid red bottlebrush flowers. A refined cultivar of the classic Bottlebrush, 'Harkness' is ideal for hedging, screening, borders, and native gardens, offering year-round structure and reliable flowering.

This variety typically grows to 1.5–2.5 metres tall, forming a neat, bushy shape that responds well to regular pruning. It produces vibrant crimson-red flowers in spring and again in late summer, attracting birds, bees, and beneficial insects. Its fine foliage releases a subtle citrus scent when brushed, adding extra sensory appeal.

‘Harkness’ thrives in full sun, tolerates light frost, and is drought-tolerant once established. It’s a resilient choice for low-maintenance landscapes, including coastal areas, urban gardens, and habitat plantings.
