Brigitta Alida Dahlia (Dahlia pinnata ‘Brigitta Alida’) captures attention with its large, fully double blooms in luminous lavender-purple highlighted by delicate silvery undertones. The slightly curved petals form a perfectly symmetrical, refined flower that stands out beautifully against dense, dark green foliage. From July until the first frost, this spectacular variety produces an abundance of elegant blooms, bringing softness, colour, and sophistication to summer gardens. Reaching 90 to 110 cm (35 to 43 in) tall, it makes a striking statement in garden beds. Not hardy in Canada, it is typically grown as an annual, although its tubers can be lifted and stored indoors over winter.

Plant the tuber in spring after all danger of frost has passed and the soil has thoroughly warmed, approximately 10 to 12 cm (4 to 5 in) deep. Choose a location in full sun with rich, loose, humus-rich, well-drained soil, spacing plants 40 to 50 cm (16 to 20 in) apart. Water regularly to maintain even soil moisture without allowing the soil to become waterlogged. Feed every two to three weeks with a fertilizer high in potassium to encourage abundant flowering. Remove spent blooms regularly to promote continuous bud production. In autumn, lift the tubers before hard frost and store them in a cool, dry, frost-free location until spring.

Brigitta Alida Dahlia (Dahlia pinnata ‘Brigitta Alida’) is perfect for elegant garden beds, flowering borders, large containers, and cut flower gardens. Its soft lavender and silvery tones pair beautifully with salvias, cosmos, Verbena bonariensis, and ornamental grasses to create romantic, sophisticated plantings. Its long stems and outstanding vase life make it a favourite for premium floral arrangements. When fully open, the flowers attract bees, butterflies, and many other pollinating insects. The petals of untreated plants may also be used with care as an edible garnish for selected desserts.

Sowing guide

It all startswith a seed.

Sowing depth

10 to 12 cm (4 to 5 in)

Sowing period

Spring

Propagation

Divide the tubers in spring, ensuring each division has at least one viable growing eye. This preserves the characteristics of the cultivar.

Growing method

Plant the tubers in spring after all danger of frost has passed and the soil has thoroughly warmed. Plant 10 to 12 cm (4 to 5 in) deep, spacing tubers 40 to 50 cm (16 to 20 in) apart in rich, loose, well-drained soil. Choose a location in full sun for abundant flowering. Water regularly without waterlogging the soil and fertilize throughout the growing season. Remove spent blooms to encourage continuous bud production. Lift the tubers before the first hard frost and store them in a cool, dry, frost-free location over winter.

Soil and care

The right care,at the right time.

Soil pH

Slightly acidic to neutral

Minimum temperature

5°C (41°F)

Care level

Intermediate

Watering

Water regularly to keep the soil evenly moist without overwatering. Reduce watering before lifting the tubers in autumn.

Soil type

Rich, loose, humus-rich, well-drained soil that remains evenly moist without becoming waterlogged. Avoid heavy, poorly drained soils.

Fertilization

Apply a fertilizer high in potassium every two to three weeks during active growth. Avoid excessive nitrogen, which encourages foliage rather than flowers.

Seasonal care

Remove spent blooms regularly to encourage continuous flowering. Water deeply during hot weather without overwatering. Fertilize every two to three weeks throughout the growing season. Lift the tubers before the first hard frost and store them in a cool, dry location over winter.

Container growing

A garden,within reach.

Recommended pot size

35 to 45 cm (14 to 18 in)
Container growing requires planning for the necessary root volume and the plant's final height. Choose a stable pot with drainage holes and a suitable planting medium. Leave enough space to respect the recommended depth and spacing, rather than overcrowding the plants to fill the pot immediately. Place the container in the indicated exposure and regularly check the moisture, especially in hot or windy weather. A pot is more exposed to temperature variations than a plant in the ground. Therefore, plan for a wintering location compatible with the plant's needs and your region's climate from the outset. Plant in spring when all risk of frost has passed and the soil is sufficiently warm. Choose a sunny spot, sheltered from strong winds, in fertile and well-drained soil. Arrange the tuberous roots with their crown and buds facing upwards, without breaking fragile attachments. Install a stake at planting if support will be needed, to avoid damaging the roots later. Water sparingly at the beginning, then adjust water intake to foliage growth. Consistently soggy soil around the tubers should be avoided, especially before the first shoots appear. Plan to bring storage organs indoors for the Quebec winter to protect them from frost.
