Callistemon viminalis ‘Slim’ (Bottlebrush) is a compact, upright variety prized for its narrow habit, lush green foliage and pale new growth. Throughout most of the year, it produces striking large red bottlebrush flowers that attract bees, butterflies, and nectar-feeding birds, adding vibrant colour and life to the garden.
Its tall, slender form makes it the ideal choice for hedging, screening, windbreaks and narrow spaces where width is limited. Hardy, low-maintenance and tolerant of frost, drought and a wide range of soils, ‘Slim’ is well suited to modern landscapes, courtyards and coastal areas. It can also be pruned to maintain a smaller hedge size of around 60 cm wide and 1.5 m high.
