Bottlebrush ‘Slim’

Slim Bottlebrush

The Bottlebrush ‘Slim’ (Callistemon viminalis ‘Slim’) is a narrow, upright evergreen shrub admired for its profusion of bright red, brush-like flowers and compact growth habit. Reaching only 6–8 feet tall and about 3–4 feet wide, this slender variety is perfect for tight spaces, borders, or containers where traditional Bottlebrush varieties might outgrow their space. Its vivid crimson flower spikes bloom from spring through fall, attracting hummingbirds, bees, and butterflies, while its narrow, fine-textured foliage provides structure and greenery year-round.

‘Slim’ Bottlebrush is a low-maintenance and drought-tolerant plant once established, making it an excellent choice for water-wise and low-care landscapes. It thrives in full sun and well-drained soil and adapts well to both coastal and urban environments. Its upright form makes it ideal for screening, accent planting, or adding vertical interest to garden beds. Hardy, versatile, and colorful, the Bottlebrush ‘Slim’ delivers beauty and function in a compact package that suits modern landscapes perfectly.

Care Instructions

Planting:
Select a sunny site with well-draining soil. Dig a hole twice the width of the root ball and plant at the same soil depth.

Watering:
Water regularly until established. Afterward, water deeply but infrequently, allowing the soil to dry slightly between watering.

Pruning:
Prune lightly after flowering to maintain its slim shape and encourage more blooms. Avoid cutting into old wood.

Pest Control:
Inspect for scale or aphids. Treat infestations with neem oil or insecticidal soap.

Soil Tips:
Prefers slightly acidic to neutral soil (pH 6.0–7.5). Mix in organic matter to enhance drainage and root health.
