Giant ‘Fleurel’ Dahlia (Dahlia ‘Fleurel’)
Product code : VAN-327-411-40
Fleurel produces very large creamy white double flowers whose finely divided tips create a fringed feathery texture. Its No1 tuber forms an upright clump approximately 90 cm tall and 50 cm wide, ideal for luminous borders and cutting gardens. Plant it 10 cm deep in full sun and fertile, humus-rich, fresh drained soil. Early support, deep watering at the base, and removal of faded flowers sustain blooming from midsummer until frost. In Canada, lift the tuber after the first frost and store it somewhere cool, dry, and frost-free through winter. Regular cutting encourages additional creamy white blooms and keeps the supported clump productive through late summer.

Giant ‘Fleurel’ Dahlia (Dahlia ‘Fleurel’) ‘Fleurel’ is a giant-flowered dahlia whose creamy white double blooms have finely divided petal tips. This fimbriated form creates a soft feathery texture while retaining the generous outline associated with Dinnerplate dahlias. According to the RHS, flowers may reach 25 cm when disbudding concentrates the plant’s energy on one bud. Each No1 tuber forms an upright clump approximately 90 cm tall and 50 cm wide with green foliage. From midsummer until the first frost, this Van Noort selection brightens borders, large containers, and cutting gardens with luminous flowers that combine easily with every colour palette.
Plant the tuber in spring after the final frost when soil has warmed. Lay it horizontally 10 cm deep with its bud facing upward in fertile, humus-rich soil that stays fresh yet drains perfectly. Choose full sun and leave 50 cm around the crown. Install support at planting to hold giant blooms without injuring roots later. Water sparingly before emergence, then deeply at the base whenever the surface dries. Pinch the shoot at 20 or 30 cm to encourage branching. Add compost and feed moderately with a fertilizer richer in potassium from bud formation. Keep foliage dry during irrigation and maintain good airflow around stems.
Place ‘Fleurel’ in the middle of a border or a white garden beside a path where its fringed petals can be appreciated. Pair it with blue salvias, purple verbenas, pink gauras, silver artemisias, and bronze grasses. For one especially large bloom, retain the central bud and remove side buds; for more stems, keep natural branching. Harvest when nearly open early in the morning and remove faded flowers. Highly double blooms provide limited pollinator access, so add simple open flowers nearby. In Canada, lift the tuber after frost and keep it somewhere cool, dry, dark, and frost-free until spring.

Growing method
After the final frost, loosen sunny soil to 30 cm and incorporate mature compost. Lay the tuber horizontally 10 cm deep with its bud upward, keeping 50 cm around the clump. Close without compacting and water sparingly before emergence to prevent rot. When shoots reach 20 to 30 cm, pinch above a leaf pair to encourage branching. Install a discreet stake or ring immediately. Water deeply at the base whenever the surface dries and apply fertilizer moderate in nitrogen and richer in potassium from bud formation. Tie stems with soft material. Remove faded flowers until frost. Once foliage blackens, cut, lift, dry, and store the tuber away from frost. Fleurel is a giant Dinnerplate dahlia with large double creamy white flowers. Broad gently curved petals create full, balanced flowerheads with refined texture. The upright clump reaches about one metre and benefits from discreet staking in windy places. Full sun and fertile humus-rich fresh drained soil support sturdy stems. Feeding moderate in nitrogen and richer in potassium accompanies bud formation. Pinching branches young shoots and removing faded flowerheads extends flowering. In Quebec, the tuber must be lifted after frost and stored somewhere cool and frost-free.

Watering
Before emergence, water only when soil becomes distinctly dry. Once stems establish, apply water deeply at the base whenever the surface begins drying, especially during bud development and heat. Let drainage work between applications. Avoid wetting double flowers and foliage in the evening because prolonged moisture favours spotting and grey mould. Fleurel is a giant Dinnerplate dahlia with large double creamy white flowers.
Soil type
Prepare fertile, humus-rich, loose, freely drained loam retaining even freshness during growth. Mature compost improves structure and supplies gentle reserves. On heavy soil, raise the planting slightly and incorporate coarse mineral material. Avoid hollows where water stands around the tuber, constantly wet substrates, and very dry ground that weakens stems and buds. Fleurel is a giant Dinnerplate dahlia with large double creamy white flowers.
Fertilization
Incorporate mature compost before planting. From active growth, use balanced fertilizer low to moderate in nitrogen, then favour a potassium-richer formula as buds form. Follow labelled rates and water afterward. Excess nitrogen produces soft stems, abundant leaves, and fewer flowers. Stop feeding several weeks before autumn lifting. Fleurel is a giant Dinnerplate dahlia with large double creamy white flowers. Broad gently curved petals create full, balanced flowerheads with refined texture.
Moisture
Maintain even soil moisture without saturation during active growth. Large double flowers become heavy after rain; good air circulation, 50 cm spacing, and support reduce breakage and slow drying. Never let thick mulch touch the crown. During storage, keep a cool dry atmosphere that prevents both extreme shrivelling and rot. Fleurel is a giant Dinnerplate dahlia with large double creamy white flowers.
Seasonal care
In spring, inspect the tuber, prepare soil, plant after frost, and install support before stems become fragile. Pinch young shoots to branch the clump. In summer, water deeply, tie with soft material, feed moderately, and remove faded flowers regularly. Harvest stems early in the morning using clean tools. Monitor slugs, aphids, earwigs, spider mites, and mould without needlessly treating neighbouring flowers. In autumn, wait until frost blackens foliage, cut stems to 10 or 25 cm, lift the tuber without injury, and let its surface dry. Label Fleurel clearly. In winter, store it somewhere cool, dry, dark, and frost-free. Inspect monthly, remove soft tissue, and prevent both condensation and complete desiccation. Fleurel is a giant Dinnerplate dahlia with large double creamy white flowers. Broad gently curved petals create full, balanced flowerheads with refined texture. The upright clump reaches about one metre and benefits from discreet staking in windy places. Full sun and fertile humus-rich fresh drained soil support sturdy stems. Feeding moderate in nitrogen and richer in potassium accompanies bud formation. Pinching branches young shoots and removing faded flowerheads extends flowering. In Quebec, the tuber must be lifted after frost and stored somewhere cool and frost-free. Double flowers suit arrangements and borders but provide little food for pollinators. Water deeply at the base when the surface dries without saturating the crown.
Container growing

Recommended pot size
At least 45 cm wide and deep
Use a stable container at least 45 cm wide and deep with numerous holes. Fill it with rich potting mix amended with compost and drainage material. Set one tuber 10 cm below the surface and immediately install a central stake or discreet cage. Keep the pot in full sun protected from strong wind. Water deeply whenever the upper centimetres dry and always empty the saucer. Feed moderately during growth, then emphasize potassium from bud formation. Pinch young shoots and remove faded flowers. Rotate the container regularly for balanced growth. After the first frost, cut stems, let the mix dry slightly, and remove the tuber for cool dry frost-free storage until spring.

Frequently asked questions
Your questions,answered.
When should Fleurel dahlia be planted?
Plant Fleurel in spring after the final frost when soil has warmed and no longer remains saturated. Lay the tuber horizontally 10 cm deep with its bud upward, keeping 50 cm clear around the crown. In cold regions, starting it indoors in a pot four to six weeks earlier advances growth, but acclimate the plant gradually before moving it outside. Water very sparingly before emergence to prevent rot, then increase moisture as shoots and roots become active. Install support immediately to protect future giant blooms from wind and rain. This careful practice supports consistent flowering and protects the delicate fringed texture of every bloom.
Why do the petals look fringed?
Fleurel belongs to the fimbriated dahlia group. The end of every petal divides into fine points with no central disc visible, giving the double bloom a soft feathery and slightly tousled texture. This form is a stable cultivar trait rather than insect damage. Good light, moderate feeding, and regular watering allow flowers to develop fully. Avoid constantly wetting the flowerheads and maintain good airflow because the many divisions retain moisture longer after heavy rain. Support also keeps blooms from resting against damp foliage. This careful practice supports consistent flowering and protects the delicate fringed texture of every bloom. This careful practice supports consistent flowering and protects the delicate fringed texture of every bloom.
How can a 25 cm flower be produced?
The RHS notes that Fleurel may reach approximately 25 cm when the plant is disbudded. To concentrate its energy, retain the central bud on a strong stem and gently remove the two side buds while they are still small. Do not use this technique on every branch because it reduces the total flower count. Provide full sun, rich drained soil, deep watering at the base, and moderate fertilizer richer in potassium. Support the selected stem firmly and protect its bloom from strong wind. Without disbudding, flowers remain abundant and naturally very large. This careful practice supports consistent flowering and protects the delicate fringed texture of every bloom.
Can Fleurel be grown in a container?
Yes, choose a stable container at least 45 cm wide and deep with large drainage holes. Fill it with fertile airy mix, plant the tuber 10 cm deep, and immediately install support. Keep the pot in full sun, water deeply when the upper few centimetres dry, and always empty its saucer. Feed moderately, pinch the shoot, and remove faded flowers. Rotate the container for balanced growth and protect fringed blooms from strong wind. After frost, remove the tuber and store it somewhere cool, dry, dark, and frost-free. This careful practice supports consistent flowering and protects the delicate fringed texture of every bloom.
How should Fleurel be overwintered in Canada?
After the first frost blackens foliage, cut stems to 10 or 15 cm. Lift widely around the crown with a fork to avoid injuring tuberous roots, gently remove loose soil, and let the surface dry in a sheltered place. Store the labelled tuber in lightly insulating material somewhere cool, dry, dark, and frost-free. Inspect it monthly, remove any soft section with a clean tool, and increase ventilation if condensation appears. Replant only after frost risk has passed and the soil has warmed. This careful practice supports consistent flowering and protects the delicate fringed texture of every bloom. This careful practice supports consistent flowering and protects the delicate fringed texture of every bloom.
