Clerodendrum trichotomum var. fargesii – Harlequin Glorybower, the Autumn Jewel of the Shrub Border

Clerodendrum trichotomum var. fargesii, commonly known as Harlequin Glorybower, is a truly spectacular large shrub or small multi-stemmed tree that delivers an extraordinary sequence of ornamental interest from late summer right through to autumn. Sweetly fragrant, pure white flowers, each cradled within a distinctive blush-pink to deep rose calyx, open in loose, airy clusters from late summer onwards, filling the surrounding air with a delicate, jasmine-like scent that draws in butterflies and bees in impressive numbers.

As the flowers fade, the display reaches an even more dramatic crescendo: vivid, turquoise-blue berries emerge from within the now-enlarged, star-shaped, crimson calyces, creating a jewel-like contrast of colour that few other garden plants can rival in autumn. This striking combination of scarlet and metallic blue persists well into the season, offering an unforgettable late-year spectacle. The variety fargesii is particularly valued for its smooth, hairless leaves and generally more refined habit compared to the straight species, making it a choice selection for ornamental planting.

The foliage of Clerodendrum trichotomum var. fargesii is broad, ovate, and carried on arching branches that give the plant a graceful, open character. Over time it develops into a handsome large shrub or small tree with an elegant, layered branching structure. Reasonably hardy in sheltered UK gardens, it performs best in a warm, protected position, where it can develop its full beauty season after season.

Planting & Care Guide

Position: Full sun to light partial shade; choose a warm, sheltered spot protected from cold winds and hard frosts to encourage the best flowering and fruit set.

Soil: Moist, fertile, well-drained soil; tolerates most soil types provided waterlogging is avoided. Incorporates well-rotted organic matter at planting to support establishment.

Watering: Keep the soil consistently moist during the growing season, particularly during dry spells. Established plants develop reasonable drought tolerance but perform best with adequate summer moisture.

Feeding: Apply a balanced general fertiliser in spring to encourage vigorous growth and a generous display of flowers and berries.

Pruning: Little pruning is required to maintain the natural, graceful habit. Remove any dead, damaged, or crossing branches in early spring. If grown as a shrub, older stems can be thinned periodically to maintain an open, airy framework. When training as a small tree, gradually remove lower branches to develop a clear stem over several seasons.

Winter Care: In colder or more exposed gardens, apply a generous mulch of bark or well-rotted compost around the base in autumn to insulate the roots. Young plants benefit most from frost protection until fully established.

Design & Planting Ideas

• Use as a bold focal point in a sheltered mixed border, where its flowers and berries can be admired at close range.

• Train as a small multi-stemmed tree to add structure and height to a courtyard, patio garden, or larger bed.

• Pair with late-flowering perennials such as salvias, dahlias, or asters to create a vibrant, richly coloured autumn planting scheme.

• Plant near seating areas or garden paths where the evening fragrance of the flowers can be fully appreciated.

• Combine with other berrying shrubs such as callicarpa or cotoneaster to amplify the impact of autumn fruit colour across the garden.

• Ideal for sheltered urban or walled gardens where a slightly exotic, sophisticated character is desired.

Guide to Planting Field-Grown Root Balled Plants

Pros:

1. Established Roots: Typically stronger, established roots ensure better initial growth.
2. Immediate Impact: Larger plants provide instant structure and aesthetics.

Cons:

1. Heavy and Bulky: Can be difficult to transport and plant due to size and weight.
2. Seasonal Availability: Generally available only in the dormant season (autumn to early spring).

Preparation for Planting:

1. Unwrap Carefully: Remove any packaging material, but leave the burlap or wire basket on.
2. Keep plants moist: Plants should be kept moist until the time of planting.

Planting Process:

1. Dig a Hole: Make a hole twice the width of the root ball and the same depth.
2. Position Plant: Place the root ball in the hole, ensuring the top is level with the ground surface.
3. Do Not Remove Root Sack: Leave the burlap or wire basket around the root ball. It is bio degradable and will rot away naturally.
4. Backfill: Fill the hole with soil, firming gently around the roots to eliminate air pockets.
5. Water: Water deeply after planting to settle the soil and avoid wilting.

Possibility of Losses:

• Initial Shock: Some plants may suffer transplant shock, leading to potential losses.
• Mitigation: Proper care and consistent watering during the establishment phase can minimise this risk.

Main Causes of Failure:

1. Improper Planting Depth: Planting too deep or too shallow can stress the roots.
2. Poor Soil Conditions: Compacted or poorly drained soil can hinder root growth.
3. Insufficient Watering: Both under-watering and over-watering can lead to plant stress and failure. Strong wind can dry leafy pants.
4. Pest and Disease: Lack of protection and monitoring can result in damage from pests and diseases.

Tips for Success:

1. Stake Larger Plants: Support with stakes to prevent wind damage.
2. Mulch: Apply a layer of mulch around the base to retain moisture and regulate temperature.
3. Regular Monitoring: Check for signs of stress, pests, and disease, and address them promptly.

By following these guidelines and providing consistent aftercare, you can successfully plant and establish field-grown root balled plants in your garden.
