Size Matters:
Choosing the Right Bottle Brush Plant for Your Landscape

Bottle brush plants are named after their cylindrical, brush-like flowers that resemble a bottle brush. These plants are popular in landscapes because they add a pop of color and texture with their bright red, pink or white flowers. However, choosing the right size of a bottle brush plant is essential to make sure it fits well in your landscape.

Choosing the Right Size of Bottle Brush Plant

Bottle brush plants come in different sizes, ranging from small shrubs to large trees. The size of the plant you choose should depend on the space you have available and the purpose you want it to serve in your landscape.

Small Bottle Brush Plants

Small bottle brush plants are ideal if you have limited space or if you want to use them as border plants or as a low hedge. They can grow up to 5-6 feet tall and wide, and they are suitable for growing in containers, making them perfect for small gardens or patios.

Some popular small bottle brush plants include the dwarf bottle brush (Callistemon citrinus ‘Little John’) and the weeping bottle brush (Callistemon viminalis ‘Little John’), which both feature bright red flowers and grow to about 3-4 feet tall and wide.

Medium Bottle Brush Plants

Medium-sized bottle brush plants are perfect for adding color and texture to larger landscapes. They can grow up to 15-20 feet tall and wide and are suitable for planting as specimen trees or as part of a mixed border.

Some popular medium-sized bottle brush plants include Callistemon viminalis ‘Captain Cook’, which features bright red flowers and grows up to 15-20 feet tall, and Callistemon ‘Great Balls of Fire’, which has large, bright red flower spikes and grows up to 12-15 feet tall.

Large Bottle Brush Plants

Large bottle brush plants are ideal for creating a focal point in larger landscapes or for providing shade. They can grow up to 30-40 feet tall and wide, making them suitable for planting in parks or along roadsides.

One popular large bottle brush plant is the Callistemon sieberi, which features white flowers and can grow up to 30-40 feet tall.
