Giant ‘Hamari Gold’ Dahlia (Dahlia ‘Hamari Gold’) ‘Hamari Gold’ is a premium Dinnerplate dahlia with massive 25 cm double flowers built from informal gently waved petals. Their deep golden yellow carries warm bronze tints reminiscent of late-summer light. Each No1 tuber forms an upright clump approximately 100 cm tall and 50 cm wide with green foliage. From midsummer until the first frost, giant blooms repeat on sturdy stems. This Van Noort selection, also recognized with a RHS Award of Garden Merit, creates a sunlit focal point in borders and arrangements. Its warm colour combines especially well with cool blue, purple, white, and bronze garden companions.
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 sturdy support at planting to hold 25 cm blooms. 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 use fertilizer richer in potassium with moderation from bud formation. Keep foliage dry while watering and maintain open airflow around the supported clump.
Place ‘Hamari Gold’ in the middle or back of a border beside a path that permits cutting its imposing flowers. Pair bronzy gold with blue salvias, purple verbenas, white gauras, chocolate cosmos, and copper grasses. Harvest nearly open stems early in the morning and continuously remove faded flowerheads. For one exceptionally large bloom, retain the central bud and remove side buds; for more stems, preserve natural branching. Highly double flowers offer limited pollinator access. In Canada, after frost, lift the tuber, let its surface dry, and store 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. Hamari Gold is a giant Dinnerplate dahlia with large double bronzy gold 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. Hamari Gold is a giant Dinnerplate dahlia with large double bronzy gold 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. Hamari Gold is a giant Dinnerplate dahlia with large double bronzy gold 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. Hamari Gold is a giant Dinnerplate dahlia with large double bronzy gold 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. Hamari Gold is a giant Dinnerplate dahlia with large double bronzy gold 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 Hamari Gold clearly. In winter, store it somewhere cool, dry, dark, and frost-free. Inspect monthly, remove soft tissue, and prevent both condensation and complete desiccation. Hamari Gold is a giant Dinnerplate dahlia with large double bronzy gold 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 Hamari Gold be planted?
Plant Hamari Gold 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. Immediately install sturdy support for the future 25 cm flowers. This careful practice supports consistent flowering and protects the giant blooms throughout summer.
Do the flowers really reach 25 cm?
Yes. Van Noort describes giant 10-inch blooms, approximately 25 cm, and the RHS profile also lists flowers reaching 25 cm. Size nevertheless depends on plant vigour, water, fertility, sunlight, and the number of buds carried by each stem. To concentrate energy on one flower, retain the central bud and remove two side buds while small. Do not disbud every branch when a larger flower count is preferred. Sturdy support and feeding moderate in nitrogen but richer in potassium sustain giant flowerheads. This careful practice supports consistent flowering and protects the giant blooms throughout summer. This careful practice supports consistent flowering and protects the giant blooms throughout summer.
Is Hamari Gold suitable for arrangements?
Yes. Immense bronzy gold flowers provide a warm focal point in arrangements and combine with blue, purple, white, and copper foliage. Cut stems early in the morning when flowerheads are nearly 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 flowers prevents seed formation and encourages new buds until frost. This careful practice supports consistent flowering and protects the giant blooms throughout summer. This careful practice supports consistent flowering and protects the giant blooms throughout summer.
Can Hamari Gold 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 sturdy 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. Protect 25 cm 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 giant blooms throughout summer. This careful practice supports consistent flowering and protects the giant blooms throughout summer.
How should Hamari Gold 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 giant blooms throughout summer. This careful practice supports consistent flowering and protects the giant blooms throughout summer.
