ABOUT
The Callistemon 'Masotti', commonly known as the Dwarf Bottlebrush, is a compact shrub known for its distinctive and attractive flowers. The plant boasts a dense, bushy growth habit, characterized by small, narrow, and evergreen leaves that provide a lush backdrop for the vibrant blooms. These leaves are typically a rich, dark green hue, lending a year-round verdancy to the plant’s appearance. The most striking feature of the Dwarf Bottlebrush is its flowers, which are what give the plant its common name. The blooms are arranged in cylindrical spikes that resemble a traditional bottlebrush or the bristles of a brush used for cleaning bottles. These flowers are a brilliant red color, adding a bold splash to the garden when the plant is in bloom. The flower spikes are often abuzz with pollinators, particularly attracted to the nectar-rich blossoms. Adding to its charm, after the flowering season, the Dwarf Bottlebrush produces small, woody capsules that contain seeds, clustered around the stems where the flowers once thrived. These capsules can persist on the plant for an extended period before releasing the seeds. The overall aesthetic of the Callistemon 'Masotti' is one of a well-proportioned, rounded shrub that provides a strong visual interest with its combination of colorful flowers and textured, evergreen foliage. It is popular in ornamental gardens for its manageable size and is often used in borders, as a low hedge, or an accent plant to bring year-round appeal and vibrancy to the landscape.

WaterBottlebrush 'Masotti' prefers consistently moist soil, so it should be watered regularly, but without waterlogging. During the active growing season in spring and summer, watering might be necessary once or twice a week depending on the climate. It's important to allow the soil to dry slightly between watering. Approximately 1 gallon per watering for a medium-sized shrub should suffice. In the cooler months, reduce watering to every two weeks or less, ensuring the plant is not sitting in overly wet soil which can lead to root rot.
LightThe Bottlebrush 'Masotti' thrives in full sun, where it can receive at least six hours of direct sunlight daily. An ideal spot would be in an open garden space or near a south-facing wall that provides ample sunlight throughout the day. Although it can tolerate partial shade, the plant will produce fewer flowers and may become leggy.
TemperatureThe Bottlebrush 'Masotti' can withstand a range of temperatures but grows best when the thermometer reads between 50°F and 90°F. It can survive brief frosts down to about 20°F, but prolonged exposure to freezing temperatures can cause damage. For optimal growth and flowering, keep the Bottlebrush 'Masotti' in a location where it is protected from extreme cold.
PruningPrune the Bottlebrush 'Masotti' to maintain shape and encourage bushier growth, remove any dead or diseased wood, and promote better airflow within the plant. The best time for pruning is after the plant has finished flowering, typically in late spring or early summer. Prune sparingly; excessive cutting back can reduce flowering in the following season. Regularly remove spent flowers to encourage a second bloom.
CleaningAs needed
SoilThe Bottlebrush 'Little John', prefers well-draining soil with a slightly acidic to neutral pH between 6.0 to 7.0. A mix of loamy soil, sand, and peat moss can work well, ensuring good drainage and aeration. Regularly adding organic matter can help maintain soil health.
RepottingThe Bottlebrush 'Little John' should be repotted every 2-3 years or when it outgrows its current pot, ensuring to use a well-draining soil mix and a slightly larger pot to accommodate its growth.
Humidity & MistingThe Bottlebrush 'Little John' tolerates a wide range of humidity levels but thrives best at moderate humidity, between 40-60%. It does not require any special humidity considerations when grown in its natural outdoor environment.

Life cycleThe common name for Callistemon 'Masotti' (PBR) is Bottlebrush 'Masotti'. The life of Bottlebrush 'Masotti' begins with seed germination, where environmental conditions trigger the dormant seed to sprout. The seedling stage follows, where the plant establishes its root system and first leaves, requiring consistent moisture and light. The vegetative growth stage is next, characterized by rapid stem and leaf development, during which the plant should be in well-draining soil and full sun to partial shade to thrive. The plant then enters the flowering stage, producing distinctive brush-like flowers that attract pollinators, generally seen in late spring to summer. As the plant matures, it enters a maintenance stage, where it needs pruning to shape and promote denser foliage and more prolific blooming in the following seasons.
PropogationPropogation time
Spring-Early Summer
The most popular method of propagating the Callistemon 'Masotti', commonly known as Dwarf Bottlebrush, is through semi-hardwood cuttings. This technique is typically performed in the late summer when growth from the current season has started to mature but is not fully hardened. To propagate by cuttings, take a 4 to 6 inch (10 to 15 centimeters) cutting from the current year's growth, ensuring it includes at least one set of leaves. Strip the leaves from the bottom half of the cutting and dip this end into a rooting hormone powder to facilitate root development. The cutting should then be placed in a well-draining potting mix, kept moist and out of direct sunlight until roots have established. This can take several weeks, during which a plastic cover can help maintain humidity. Once rooted, the new Dwarf Bottlebrush plants can be gradually acclimatized to outdoor conditions before being planted in their final location.
