Dahlia ‘Glenbank Lavender Blush’ Tuber | Lavender, Mauve and Cream Decorative Dahlia

Create a soft, romantic garden display with Dahlia ‘Glenbank Lavender Blush’, an Australian-bred decorative dahlia producing beautifully layered flowers in pale lavender, purple-mauve, blush pink and creamy-white tones.

The balance of colours changes naturally as the flowers open. Some blooms may appear predominantly creamy white with softly blushed edges, while others develop stronger lavender and mauve colouring.

Growing up to approximately 1.5m tall with strong flowering stems, this distinctive variety is especially valuable for cut-flower gardens, bouquets and elegant floral arrangements.

EXAMPLE IMAGE ONLY: The flower image shows an example of the expected mature bloom. The balance and intensity of the cream, lavender, mauve and blush-pink colouring may vary naturally according to climate, growing conditions, lighting and bloom maturity. The supplied product is a dormant tuber—not a flowering plant.

Supplied as Dormant Tubers

Supplied as the selected quantity of dormant Dahlia ‘Glenbank Lavender Blush’ tubers.

Dahlia tubers naturally vary in size, shape and appearance. A smaller tuber can grow just as successfully as a larger tuber when it is healthy and has a viable eye or growing point.

Tubers may arrive without visible shoots or roots. This is normal while they are dormant.

Planting Instructions

Plant Dahlia ‘Glenbank Lavender Blush’ during spring once the danger of frost has passed and the soil has begun to warm.

Choose a sunny position with fertile, free-draining soil. Avoid low-lying areas where water collects, as dormant tubers can rot when planted in continually wet soil.

Lay each tuber horizontally approximately 5–10cm below the soil surface, with the crown or growing point facing upwards. Cover gently with soil.

Space plants approximately 60cm apart to provide adequate room for growth and good airflow.

Install a sturdy stake at planting time. This is a tall-growing variety, and adding support before growth begins helps prevent accidental damage to the tuber later.

Avoid heavy watering immediately after planting. If the soil is already moist, wait until shoots begin appearing before commencing regular watering.

Care Instructions

Position

Grow Dahlia ‘Glenbank Lavender Blush’ in full sun, ideally with at least six hours of direct sunlight each day.

In hot Australian climates, protection from intense late-afternoon sun may help reduce heat stress and preserve the softer lavender, cream and blush flower colouring.

Insufficient sunlight can produce weaker stems and fewer flowers.

Soil

Plant in fertile, humus-rich and free-draining soil.

Improve the planting area with compost or well-aged organic matter before planting. Heavy clay soil should be amended to improve drainage, or the tuber can be grown in a raised garden bed or large container.

Excellent drainage is particularly important in subtropical climates and areas receiving heavy summer rainfall.

Watering

Once shoots emerge, water deeply and regularly while allowing the upper soil surface to begin drying between applications.

Increase watering during hot, dry or windy weather. Avoid keeping the soil continually saturated, particularly around the crown and tuber.

Water near the base of the plant where possible to reduce prolonged moisture on the foliage and flowers.

Feeding

Apply a balanced or flowering-plant fertiliser once active growth is established.

Avoid excessive nitrogen, which can encourage abundant foliage at the expense of flower production. Additional flowering fertiliser may be applied as buds begin developing, following the product label directions.

Staking

Dahlia ‘Glenbank Lavender Blush’ can grow up to approximately 1.5m tall and should be supported.

Install a sturdy stake at planting time and secure the stems loosely as the plant grows. Allow enough space for natural movement and stem expansion.

Additional support may be required in exposed or windy positions.

Pinching

For bushier growth and additional flowering stems, pinch out the central growing tip once the young plant has developed approximately four sets of leaves.

Pinching may delay the first flowers slightly but can encourage a fuller plant with more flowering branches.

Deadheading and Cutting

Remove faded flowers regularly to encourage continued blooming and prevent the plant from directing energy into seed production.

For cut-flower use, harvest blooms before they are completely open. Cut during the cooler part of the morning and place the stems into clean water promptly.

Regular cutting and deadheading can help extend the flowering season.

Hot and Humid Climates

In subtropical and humid regions, provide excellent drainage and generous spacing between plants.

Good airflow helps reduce the risk of fungal problems. Avoid continually wet foliage and water early enough for the leaves to dry before evening.

Protection from the hottest afternoon sun may help maintain flower quality and preserve the softer pastel colouring.

End-of-Season Care

After flowering, allow the foliage to remain until it begins yellowing and dying back naturally. This enables the plant to return energy to its tuber.

In mild climates with free-draining soil, the tuber may be left in the ground during dormancy. Mark the planting position and keep the area relatively dry.

In cold, frost-prone or persistently wet climates, lift the tuber after the foliage has died back. Allow it to dry before storing it in a cool, dark, frost-free and well-ventilated location.
