Detailed Description:
Callistemon viminalis 'Captain Cook' is a popular and well-regarded bottlebrush cultivar selected for its compact size and heavy flowering. This smaller form of the Weeping Bottlebrush reaches between 1.5 and 2.5 meters tall, making it ideal for suburban gardens, courtyards, or native garden borders where space is limited but impact is desired.
In spring, the plant becomes covered in bright red flower spikes that resemble bottlebrushes, each packed with nectar-rich stamens that attract a wide range of pollinators. Birds and bees in particular are drawn to the blooms, making it an excellent choice for wildlife-friendly planting. Spot flowering may continue during the warmer months, extending its seasonal interest.
The plant’s upright and dense structure means it rarely needs shaping, but it responds well to light pruning after flowering, encouraging a bushier appearance and even more blooms in the following season. The narrow green leaves contribute to its neat look, and its resilience makes it suitable for a variety of climates and soil types.
Growth and Maintenance:
-
Watering: Water regularly during establishment. Once established, it is tolerant of dry spells and light frost
-
Pruning: Light pruning after flowering will maintain symmetry and encourage compact growth
-
General Care: Remove any dead or crossing branches as needed to keep the plant healthy
-
Fertilising: Apply a general all-purpose fertiliser annually in spring to support vigorous growth and flowering
