Café au Lait Royal Dahlia (Dahlia × pinnata ‘Café au Lait Royal’) is admired for its enormous decorative blooms in soft mauve-pink tones. Broad, gently ruffled petals create a full, airy, and luxurious appearance that stands out beautifully against dense, vigorous, dark green foliage. Blooming from July until the first frost, this variety reaches approximately 110 cm (43 in) tall and quickly becomes a striking focal point in summer landscapes. Not hardy in Canada, this tuberous perennial is typically grown as an annual, although the tuber can be lifted in autumn 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 cm (4 in) deep. Choose a location in full sun with rich, loose, humus-rich, well-drained soil, spacing plants about 50 cm (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. Install a sturdy stake at planting time to support the large flower stems. Remove spent blooms regularly, then lift the tuber before hard frost and store it in a cool, dry, frost-free location until spring.

Café au Lait Royal Dahlia is perfect for large garden beds, sunny borders, generous containers, and cut flower gardens. Its soft mauve-pink tones pair beautifully with baby’s breath, cosmos, salvias, pastel perennials, and ornamental grasses to create romantic, refined displays. Its enormous blooms have excellent vase life and are especially prized for wedding bouquets and premium floral arrangements. When fully open, the flowers also attract bees, butterflies, and many other pollinating insects throughout the season.

Planting guide

Plant well.Grow beautifully.

Planting depth

10 cm (4 in)

Best planting time

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 approximately 10 cm (4 in) deep, spacing tubers about 50 cm (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. Install a sturdy stake at planting time to support the large flower stems. 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

Install sturdy stakes at planting time to support the heavy flower stems. Remove spent blooms regularly to prolong flowering. Water deeply during hot weather without overwatering. 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

45 to 50 cm (18 to 20 in)
Container growing requires anticipating the necessary volume for the roots and the plant's final height. Choose a stable pot with drainage holes and a substrate suitable for planting. Leave enough space to respect recommended depth and spacing, rather than crowding plants to immediately fill the pot. 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 ground planting. Therefore, plan an overwintering 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 warmed. Choose a sunny location, 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 start, then adjust watering based on foliage growth. Constantly waterlogged soil around the tubers should be avoided, especially before the first shoots appear. Plan to bring storage organs indoors to protect them from frost during the Quebec winter.
