Weeping Bottlebrush Standard

Weeping Bottlebrush Standard

A striking flowering tree featuring cascading branches and vivid red, brush-like blooms.

Callistemon viminalis

Also known as Melaleuca viminalis

Add graceful movement and brilliant color with the Weeping Bottlebrush Standard. Its slender, arching branches and narrow green leaves create a flowing canopy accented by distinctive scarlet flowers.

“Standard” describes a plant trained with a clear trunk and an elevated crown. It refers to the plant’s shape, rather than a dwarf variety or a fixed mature size.

Ideal For

Specimen planting, sunny courtyards, spacious garden beds, and large patio containers where the species is appropriate for the region.

Florida planting note: UF/IFAS currently classifies this species as High Invasion Risk and does not recommend it for planting in Florida. Consider this assessment before selecting it for a landscape project. assessment.ifas.ufl.edu

💧 Care & Maintenance Guide

Light:
Performs best in full sun. Choose an open location with plenty of direct sunlight.

Watering:
Water regularly while establishing. Once established, the tree tolerates some drought, though consistent moisture supports growth and flowering. Avoid waterlogged soil.

Soil:
Prefers well-draining soil. It tolerates several soil textures, provided excess water can drain away.

Temperature:
Best suited to warm climates. Protect young and container-grown plants from frost and freezing conditions.

Fertilization:
Feed as needed during active growth with a fertilizer suitable for flowering trees, following label directions. ask.ifas.ufl.edu

Pruning:
Remove shoots developing along the clear trunk to maintain the standard form. Lightly shape the canopy after flowering, retaining its natural cascading branches. Remove dead or damaged growth as needed.

Spacing:
Plan for the mature canopy, rather than the nursery size. Allow adequate clearance from buildings, neighboring trees, and walkways where hanging branches could obstruct access.

🌺 Flowering Tip

Give the tree plenty of sunlight and avoid frequent shearing. Light shaping after the main flowering period helps preserve its graceful form and seasonal display.

Common Issues

Poor drainage can lead to root rot. Watch for mites, scale, and mealybugs. Cankers or abnormal twig growth may also occur; investigate persistent branch dieback. ask.ifas.ufl.edu

📦 What You’ll Receive

A Weeping Bottlebrush Standard — Callistemon viminalis in the container size selected, trained with a clear trunk and elevated canopy.

Overall height, trunk thickness, canopy fullness, and flower coverage vary naturally with plant size and season.

💡 Acclimation Tip

Gradually introduce plants grown under nursery shade to stronger sunlight. Monitor soil moisture closely during establishment, especially in containers.

⚠️ Safety Note

The ASPCA lists Callistemon viminalis as non-toxic to dogs, cats, and horses. Discourage pets from chewing plant material, as ingestion can still cause digestive upset. ASPCA

Landscape Use

Where regionally appropriate, the standard form creates an elevated flowering focal point with room beneath the canopy for lower planting. Allow space for its hanging branches, and account for the species’ mature size and local invasive-plant guidance.
