La Belle Époque Dahlia (Dahlia pinnata ‘La Belle Époque’) captivates with its large, fully double blooms in warm shades of copper, apricot, and dusty pink. As the flowers mature, their colours subtly evolve, creating a refined, multi-toned display reminiscent of the elegance of old-fashioned gardens. Dense, dark green foliage beautifully highlights the richness of its abundant blooms, which appear from July until the first frost. Reaching approximately 80 to 100 cm (32 to 40 in) tall, this spectacular variety brings softness and sophistication to summer landscapes. Not hardy in Canada, this tuberous perennial is typically grown as an annual, although its tuber 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 keep the soil evenly moist without allowing it to become waterlogged. Apply a fertilizer high in potassium every two to three weeks throughout the growing season. Remove spent blooms regularly to encourage continuous bud production. In autumn, lift the tuber before hard frost and store it in a cool, dry, frost-free location until spring.
La Belle Époque Dahlia (Dahlia pinnata ‘La Belle Époque’) is an outstanding choice for romantic borders, colourful garden beds, large containers, and cutting gardens. Its coppery, apricot-toned blooms pair beautifully with cosmos, baby's breath, salvias, pastel-coloured perennials, and ornamental grasses to create elegant, timeless plantings. The large flowers have exceptional vase life and are especially prized for wedding bouquets and refined floral arrangements. When fully open, they also attract bees, butterflies, and many other pollinating insects. Petals harvested from untreated plants may also be used to decorate selected desserts and pastries.
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 allowing the soil to become waterlogged and fertilize throughout the growing season. Remove spent blooms regularly 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 prolong 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 gardening requires you to plan for the necessary volume for the roots and the final height of the plant. Choose a stable pot with drainage holes and a substrate suitable for planting. Leave enough space to respect the recommended depth and spacing, rather than crowding the plants to fill the pot immediately. Place the container in the recommended exposure and regularly check the moisture, especially in hot or windy weather. A pot is more exposed to temperature variations than planting directly in the ground. Therefore, from the outset, plan a wintering location compatible with the needs of the plant and your region's climate. Plant in spring when all risk of frost has passed and the soil is sufficiently warmed. Choose a sunny spot, sheltered from strong winds, in fertile, well-drained soil. Arrange the tuberous roots with their crown and buds facing upwards, without breaking the fragile attachments. Install a stake at the time of planting if support will be needed, to avoid damaging the roots later. Water sparingly at the start, then adjust the water supply to the foliage growth. Constantly saturated soil around the tubers should be avoided, especially before the appearance of the first shoots. Plan to bring the storage organs indoors, away from frost, for the Quebec winter.
