What Type of Dahlia Is ‘Café au Lait’?
Café au Lait is a dinner plate decorative dahlia.
This means it produces:
- Very large, fully double flowers
- Broad, gently curved petals
- Soft, rounded blooms with a relaxed shape
It is grown primarily for its flower size and colour rather than compact growth.
Flower Colour and Appearance
Café au Lait is famous for its subtle, ever-changing colour.
Typical shades include:
- Cream
- Blush pink
- Beige
- Soft peach
No two flowers are exactly the same, and colour can vary depending on weather, soil, and season. Cooler conditions often bring out pinker tones, while warmer weather produces creamier flowers.
Blooms can reach 20–25 cm (8–10 inches) across.
Height and Spread
Café au Lait is a tall, vigorous dahlia.
Expected size:
- Height: around 120–150 cm
- Spread: around 60–75 cm
Because of its height and heavy flowers, staking is essential.
When Does Dahlia ‘Café au Lait’ Flower?
Flowering period:
- July to October
- Continues until the first frost
Regular deadheading is essential to keep plants flowering continuously.
How to Grow Dahlia ‘Café au Lait’
When to Plant
- Start tubers indoors in March or early April for earlier blooms
- Plant outdoors in late April to May, once all risk of frost has passed
Position
- Full sun is essential for large flowers
- Choose a sheltered spot to protect stems from wind
Soil
- Fertile, moisture-retentive but free-draining soil
- Improve soil with compost or well-rotted manure
Avoid planting in cold or waterlogged ground.
Caring for Café au Lait Dahlias
To get the best results:
- Water deeply and regularly, especially in dry weather
- Feed every 1–2 weeks once buds appear (high-potash feed works well)
- Stake early to prevent damage later
- Deadhead spent flowers frequently
Pinching out early shoots can encourage more flowering stems, though it may slightly reduce flower size.
Is Café au Lait Hardy?
No — like all dahlias, Café au Lait is a tender perennial.
In the UK you should:
- Lift tubers after the first frost blackens the foliage
- Dry them thoroughly
- Store frost-free in a cool, dry place over winter
Leaving tubers in the ground is risky, even in mild areas.
Does Café au Lait Come Back Every Year?
Yes — Café au Lait will come back every year if the tubers survive winter.
With correct overwintering:
- Plants usually become stronger each year
- Tubers multiply and can be divided in spring
- Flowering often improves with maturity
Is Café au Lait Good for Cut Flowers?
Absolutely — it’s one of the best cut dahlias available.
- Huge, dramatic blooms
- Very popular for wedding and event flowers
- Strong stems (when staked properly)
Cut flowers early in the morning when fully open for best vase life.
