ABOUT
Callistemon linearis, commonly known as the narrow-leaved bottlebrush, is a striking shrub characterized by its distinctive cylindrical, brush-like flowers. The flowers are typically a brilliant red, though they can occasionally be found in shades of pink or even greenish hues. These dramatic blossoms are composed of numerous individual flowers with long, protruding stamen, which give them the appearance of a traditional bottle brush. The plant's foliage is comprised of slender, linear leaves that are often arranged alternately along the stems, and they usually have a glossy texture with a firm and slightly leathery feel. The leaves are generally a vibrant green color, emphasizing the contrast with the bright flowers. The narrow-leaved bottlebrush can vary in its habit, sometimes presenting a weeping form with branches that drape gracefully. This plant is particularly loved by pollinators like bees and birds, who are attracted to the splashy flowers and the nectar and pollen they contain. The overall appearance of Callistemon linearis is one that is both architectural and ornamental, making it a popular choice for gardeners looking to add a touch of drama and natural beauty to their landscapes.

Water
For the Bottlebrush plant, Callistemon linearis, water deeply until moisture seeps out of the drainage holes, then allow the soil to nearly dry out before watering again. This will usually equate to watering once a week during active growth periods in spring and summer, but the frequency may decrease to once every two to three weeks during winter. It is important to avoid overwatering, making sure the plant is not left sitting in water. In terms of the amount, watering with approximately 1 to 1.5 gallons every time should suffice, but always check the soil moisture level as a guide.
Light
Bottlebrush plants thrive in full sun exposure, so place Callistemon linearis where it can receive at least 6 to 8 hours of direct sunlight daily. An ideal spot for the plant would be in a south-facing garden or near a south-facing window where it gets ample light. Inadequate light may result in less vigorous growth and fewer flowers.
Temperature
The Bottlebrush, Callistemon linearis, prefers warmer climates and does best between 50°F and 90°F. It can survive minor frosts, but temperatures below 20°F may damage the plant. Ideally, keep the plant in an environment where temperatures do not drop significantly lower than 40°F at night.
Pruning
Prune Bottlebrush plants to maintain shape and encourage bushier growth. Pruning is best done after flowering, typically in late spring or early summer, by removing any spent flower spikes and shaping the plant as desired. Regular pruning is not required; doing so annually or biennially is generally enough.
Cleaning
As needed
Soil
Bottlebrush plants prefer well-draining soil rich in organic matter with a slightly acidic to neutral pH between 6.0 and 7.0. A good soil mix for bottlebrush consists of equal parts peat, loam, and coarse sand. Regularly check the pH to ensure it remains optimal for the plant’s health.
Repotting
Bottlebrush plants should be repotted every 2-3 years to encourage healthy growth. Choose a pot that is only slightly larger than the previous one because a too-large pot can lead to water retention and root rot. Repot in spring before the new growth starts.
Humidity & Misting
Bottlebrush plants do well in moderate to high humidity levels. They are adaptable but prefer a humidity level of around 40-50%. If the indoor air is too dry, occasional misting can help raise the humidity around the plant.
Suitable locations
Indoor
Place near a sunny window; water when the topsoil is dry.
Outdoor
Full sun, protect from frost, water when dry, prune as needed.
Hardiness zone
9-11 USDA
Life cycle
Callistemon linearis, commonly known as the Narrow-leaved Bottlebrush, begins its life as a seed, which upon germination gives rise to a seedling. The seedling stage involves the development of the root system and the first leaves. As it matures into a vegetative stage, the plant experiences growth in foliage and branches, forming the characteristic narrow leaves. Upon reaching maturity, the Narrow-leaved Bottlebrush produces distinctive red or pink flower spikes comprised of numerous individual flowers, which attract pollinators such as birds and bees. After pollination, the flowers develop into small woody capsules that contain seeds, completing the reproductive cycle. Over time, these capsules release seeds, starting a new generation of plants, and the parent plant may enter a period of dormancy during adverse conditions, only to resume growth with the return of favorable seasons.
Propogation
Propogation time
Spring-Early Summer
Propogation: Callistemon linearis, commonly known as the Narrow-leaved Bottlebrush, is typically propagated during the warmer months, spring through summer, to take advantage of the plant's active growth phase. The most popular method of propagation for this species is through semi-hardwood cuttings. To do this, a gardener would cut a healthy piece of semi-hardwood stem from the current or previous year's growth, approximately 4 to 6 inches (10 to 15 centimeters) in length. The lower leaves are then stripped from the cutting, and the base is dipped into a rooting hormone to encourage root development. This cutting is then planted in a well-draining soil mix, often kept moist but not waterlogged. Cuttings are typically placed in a warm environment with bright, indirect light. Root development usually takes several weeks, after which the new plant can be gradually acclimatized to outdoor conditions and eventually transplanted.
