Bottlebrush
Scientific name: Callistemon citrinus
☘️ Toxicity: Safe for cats
☀️ Ideal light: Full sun
💧 Watering: Low to moderate; tolerates short dry periods once established
The Bottlebrush is a vibrant, woody shrub native to Australia, named after its distinctive red, brush-like flowers. Highly ornamental and easy to grow, it’s a favorite among landscapers for sunny gardens and pollinator-friendly spaces. Hardy, adaptable, and non-toxic to cats, it’s a safe and stunning choice for outdoor areas.
Essential care
- Light: Requires full sun to produce abundant flowers and dense foliage.
- Water: Moderate; allow the topsoil to dry between waterings. Once mature, it tolerates short droughts.
- Soil: Prefers well-draining, slightly sandy soil. A mix of garden soil, sand, and compost works well.
- Environment: Thrives in warm, ventilated, and sunny areas. Tolerates wind and coastal conditions.
- Fertilization: Apply organic fertilizer or NPK 10-10-10 every 45 days during spring and summer.
- Maintenance: Prune lightly after flowering to maintain shape and encourage new blooms.
Pests and diseases
- Aphids and scale insects: Can appear on young shoots; treat with diluted neem oil.
- Fungal root rot: Avoid overwatering and ensure good drainage to prevent root damage.
- Yellow leaves: Usually caused by poor soil or irregular watering — adjust care accordingly.
Propagation
- Cuttings: Take semi-woody cuttings after flowering and root in light, moist substrate.
- Seeds: Also possible, but slower. Sow in sandy soil and keep moist until germination.
Cat safety
- Classification: Non-toxic to cats, according to ASPCA and botanical databases.
- Interaction: Safe for curious cats; its firm texture and mild scent discourage chewing.
- Extra benefit: Its flowers attract bees, butterflies, and hummingbirds — enriching the garden ecosystem.
💡 The bottlebrush gets its name from its unique flower shape, which resembles the brushes once used to clean bottles. When crushed, its leaves release a soft lemony scent — a signature trait of the species.
