Callistemon John Mashlan

Bottlebrush

Callistemon John Mashlan is a vigorous shrub renowned for its attractive foliage and bottlebrush like flowers. New leaves emerge silver-pink and turn mid-green as they age. The foliage serves as a pleasant backdrop to the masses of pink, bottlebrush-like flowers that appear in clusters from spring through autumn. It typically grows to 4 m tall and 3 m wide but is often pruned back to just behind the flowers after the spring flush. Callistemon John Mashlan is commonly used for screening and shelter, grown as a specimen, added to a mixed planting, or clipped into a hedge.

How to grow Callistemon John Mashlan

To grow Callistemon 'John Mashlan', select a full sun location with well-drained soil, as this plant thrives with ample sunlight and good drainage. Enrich the soil with organic compost before planting to promote healthy root development. Water regularly during the first year to help the plant establish, then reduce watering as it matures, since it becomes highly drought-tolerant. Light pruning after flowering encourages a dense, compact shape and more prolific blooming in the next season. Feed with a low-phosphorus, slow-release fertiliser for Australian natives in early spring to support strong growth and vibrant flowering. Mulch around the base to retain moisture and suppress weeds, but avoid piling mulch against the stem to prevent rot. 'John Mashlan' typically grows into a medium-sized shrub with rich crimson-red bottlebrush flowers, making it ideal for use as a feature plant, informal screen, or wildlife-attracting garden addition.
