What Is An Bottle Brush ?
Callistemon is a genus of shrubs in the family Myrtaceae, first described as a genus in 1814. The entire genus is endemic to Australia, but is widely cultivated and naturalized in scattered locations in many other regions.
What Are The Different Types Of Bottle Brush Plants?
1. Red Alert
Red Alert rarely blooms, making it ideal for minimal-maintenance gardens. Instead, it produces bright red new leaves during the fall months and also in the spring, providing a nice contrast to the bright foliage the rest of the year.
2. Better John
Callistemon was developed as a further development of Little John. Reaching just 60cm to 1.2m in height and 60 to 90cm in width, it retains the small size of its parent plant, but is easier to grow, roots faster and produces bright blue-green leaves. Small deep red flowers bloom from September to November.
3. Slim
Callistemon viminalis is ideal for hedging, especially in small confined spaces. It naturally grows up to 3m in height and 1.3m in width, but can be cut back to about 1.5m x 60cm. Requires minimal pruning and unlike most callistemons, its branches extend all the way to the ground, leaving no ugly gaps in your hedge.
4. Green John
Green John is an exquisite little bottle brush no more than 1 meter tall. The new lime green leaves are longer than those on Little or Better John, but then the leaves mature to a deeper green colour. Beautifully shaped red brush flowers form a beautiful contrast with the dense foliage. Grows up to 1 meter in height and 60 cm in width.

Keep the soil moist, but don't overwater. This will help prevent the development of fungal diseases such as root rot.
5. Nourishment
Bottlebrush can be fertilized two to four times a year. Fertilize small trees with half a cup of Sunniland 6-6-6 every three months. For larger trees, fertilize in March and September with 2 to 3 pounds of Sunniland 6-6-6 or Espoma Tree-Tone, spread lightly over the entire root base. Do not overfertilize.
6. Issues
Bottle brushes are not affected by pests. However, if the soil is too wet, fungi and twigs that damage the roots and crown can become a problem. If new branches appear to be growing, remove them and allow the soil to dry. To prevent diseases, make sure the bottle brush has good air circulation and keep the plants dry.
