‘Palmares’ Dahlia (Dahlia × hortensis) forms an upright branching clump approximately 80 cm tall and 50 cm wide. Fully double, regular, nearly spherical Ball flowers measure about 8.5 cm. Yellow-orange florets, bright greenish yellow at the base and traced with purple veins, also reveal purple undersides. Divided green foliage accompanies sturdy stems that may carry purple colouring. From midsummer until the first frost, this Van Noort No. 1 tuber suits sunny borders, large containers, and arrangements. Its warm palette remains refined because the veining is precise rather than irregular. The registered cultivar therefore combines dependable garden structure with unusually detailed colouring.

Plant the tuber in spring after the final frost when soil has warmed and drained. Lay it 10 cm deep with its bud facing upward in fertile, humus-rich soil that remains moist yet drains freely. Leave 50 cm around the crown and install discreet support at planting. Water sparingly before emergence, then deeply at soil level whenever the surface begins to dry. Pinch the young shoot between 20 and 30 cm to encourage several branches. Incorporate mature compost, then apply moderate fertilizer richer in potassium once buds appear. Avoid standing water, excessive nitrogen, and irrigation over foliage. Maintain open airflow during humid weather and check moisture before adding more water.

Place Palmares beside a path where its orange, yellow, and purple nuances can be examined. Pair it with blue salvias, white gauras, purple verbenas, silver artemisias, or bronze grasses that emphasize warmth without overwhelming it. Harvest stems early in the morning when flowerheads are fully open, then remove faded flowers regularly to renew buds. Highly double blooms provide little accessible pollen, so include nearby simple flowers for pollinators. Watch for slugs, aphids, earwigs, and spider mites while maintaining generous airflow. In cold Canadian climates, lift the tuber after the first frost, dry its surface, label it, and store it somewhere cool, dry, dark, and frost-free until spring.

Soil and care

Soil & care

Soil pH

Slightly acidic to neutral

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.

Minimum temperature

5 °C (41 °F)

Care level

Moderate

Watering

Régulier pendant la croissance, sans détremper le sol; arrosez au pied lorsque la surface sèche.

Soil type

Fertile, meuble et bien drainé

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.

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 15 cm, lift the tuber without injury, and let its surface dry. Label Palmares clearly. In winter, store it somewhere cool, dry, dark, and frost-free. Inspect monthly, remove soft tissue, and prevent both condensation and complete desiccation. The upright clump reaches about 80 cm 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 colder Canadian regions, 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.

Growing in containers

Container growing

Recommended pot size

at least 45 cm (18 in.) in diameter and depth

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.

Bloom period

Fully double Palmares flowers are very large and repeat from midsummer until the first frost. Broad orange, yellow, and purple veined petals form full, balanced, luminous Ball blooms. Cut faded flowerheads above a leaf pair to renew buds. Support and good airflow protect this delicate texture after rainfall. This attention preserves vigour and the quality of its large orange, yellow, and purple veined flowers.

Harvest

July to October. Cut fully open flowers for the best vase life.

Companion plants & uses

Companion plants

Pair Palmares with blue salvias, purple verbenas, white gauras, chocolate cosmos, sweet alyssum, and bronze grasses sharing sun and drained soil. Airy silhouettes and simple flowers highlight rounded Ball flowerheads while providing insects with more accessible resources. Keep 50 cm around the tuber and avoid highly aggressive roots or plants requiring constantly dry ground. This attention preserves vigour and the quality of its large orange, yellow, and purple veined flowers.

Other recommended plants

Les gauras blancs, sauges bleues et graminées légères accompagnent ses fleurs dans une bordure ensoleillée.

Garden use

Place Palmares in the middle of a sunny border before bronze grasses and behind lower plants. Install support at planting so it disappears within foliage. Nearby, use blue salvias, purple verbenas, white gauras, chocolate cosmos, and sweet alyssum whose simple forms contrast with highly double blooms. Repeat several orange, yellow, and purple veined or cream tones farther through the bed to connect the scene without making it heavy. In a cutting garden, leave enough access to harvest stems without breaking neighbours. Pinch the clump early to obtain several flowering branches. Open-flowered plants provide pollen and nectar because Palmares remains mainly ornamental. In autumn, lift the tuber before deep soil freezing and label it clearly so the same palette can be rebuilt the following spring. The upright clump reaches about 80 cm 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.

Frequently asked questions

When should Palmares dahlia be planted?

Plant Palmares 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, leaving approximately 50 cm 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 discreet support at planting when the position receives strong winds through summer. Check the soil surface before every additional watering outdoors.

Are all flower patterns identical?

No. The RHS International Dahlia Register describes yellow-orange petals carrying purple veins. Their distribution varies naturally among flowerheads, giving every bloom its own veined design. Opening stage, light, and temperature may also slightly alter apparent intensity. This variability is a desirable Palmares characteristic, not a sign of disease. Place the clump beside a path to examine these differences and combine several flowers in one arrangement to emphasize the contrasts. Consistent full-sun culture encourages sturdy stems, regular flowering, and clear colours through the productive season. Compare several freshly opened blooms to appreciate the complete range of markings.

Is Palmares suitable for arrangements?

Yes. Its firm spherical fully double flowers add geometric structure to arrangements, and every veined pattern becomes a distinctive detail. Cut stems early in the morning when flowerheads are fully open because dahlias develop little after harvest. Use a clean tool, remove leaves that would sit in water, and immediately place stems in a cool bucket. Refresh vase water and recut ends regularly. Frequent harvesting combined with removing faded flowerheads prevents seed formation and encourages the plant to produce fresh buds until the first frost, extending material available for colourful seasonal displays in the home and garden all summer long.

Can Palmares grow in a container?

Yes. Its approximately 80 cm height suits a stable container at least 40 cm wide and deep with large drainage holes. Fill it with fertile airy mix, plant the tuber 10 cm deep, and install discreet support. Keep the pot in full sun, water deeply when the upper few centimetres dry, and always empty its saucer. Feed moderately with additional potassium once buds appear, pinch the shoot, and remove faded flowers. Rotate the container for balanced growth. Before frost, lift the tuber and store it somewhere cool, dry, dark, and frost-free until the following spring. Inspect drainage after every heavy rain.

How should Palmares 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 enough for active growth. Keep each cultivar clearly labelled throughout storage and discard severely rotted material promptly outdoors.
