The package provides a variable assortment of giant dahlias that may flower in red, yellow, pink, purple, or orange. Four tubers do not guarantee one exact colour each or the presence of every listed shade because this is a mix. Variability is part of its appeal. As each clump flowers, record its colour on a durable label. At lifting time, transfer the label to the matching tuber. You may then recreate the surprise effect or arrange a more precise palette the following year. Dinnerplate Mix contains four giant dahlias whose colours vary from one tuber to another. Very large flowers may display red, yellow, pink, purple, or orange tones.

Giant Dinnerplate Dahlia Mix (Dahlia ‘Dinnerplate Mix’) Dinnerplate Mix combines four No1 tubers of giant-flowered dahlias in an assortment of colours. Depending on the tubers packed, flowerheads may display red, yellow, pink, purple, or orange; the exact combination remains a horticultural surprise and every plant keeps its own colour. Large double blooms unfold on upright clumps approximately 100 cm tall and 50 cm wide. Green foliage creates a dense screen beneath flowering stems. From midsummer until the first frost, this Van Noort mix produces a spectacular succession for borders, large containers, and cutting gardens, with enough variation to create a complete display from one package.
Plant the four tubers in spring after the final frost once soil has warmed. Lay them horizontally 10 cm deep with buds facing upward, keeping 50 cm between every crown. Choose full sun or very light partial shade in fertile, humus-rich soil that remains fresh yet drains perfectly. Install a stake or support ring beside every tuber before stems lengthen. Water sparingly before emergence, then deeply at the base whenever the surface dries. Add compost, pinch young shoots to encourage branching, and use fertilizer moderate in nitrogen and richer in potassium from bud formation. Keep labels beside each plant if tracking individual colours matters.
Group the four dahlias as an island in the middle or back of a border, or distribute them through a cutting garden to discover their colours individually. Pair the mix with blue salvias, purple verbenas, white gauras, chocolate cosmos, and bronze grasses; airy forms balance the volume of Dinnerplate blooms. Harvest nearly open stems in the morning and remove faded flowerheads continuously. Highly double flowers are mainly ornamental, so add simple open blooms for pollinators. In Quebec, after the first frost, cut stems, lift every tuber, let its surface dry, label the observed colour, and store it somewhere cool, dry, dark, and frost-free until spring.

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. Dinnerplate Mix is a giant Dinnerplate dahlia with large double mixed colours 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. Dinnerplate Mix is a giant Dinnerplate dahlia with large double mixed colours 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. Dinnerplate Mix is a giant Dinnerplate dahlia with large double mixed colours flowers. Narrow petals split at their tips and produce a highly textured feathery effect.
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 giant-scale, lift the tuber without injury, and let its surface dry. Label Dinnerplate Mix clearly. In winter, store it somewhere cool, dry, dark, and frost-free. Inspect monthly, remove soft tissue, and prevent both condensation and complete desiccation. Dinnerplate Mix is a giant Dinnerplate dahlia with large double mixed colours flowers. Narrow petals split at their tips and produce a highly textured feathery effect. 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
A controlled environment.
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 four tubers 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
Everything toknow.
Leave 50 cm between the centres of future clumps. Arrange them as a square, diamond, staggered line, or distribute them through separate areas. Loosen a sufficiently large zone, lay every tuber horizontally 10 cm deep, and install its support immediately. Do not crowd plants for a denser effect because mature foliage fills the space and air must circulate around large flowers. Keep discreet access for watering at the base, removing faded flowerheads, and harvesting stems. Dinnerplate Mix contains four giant dahlias whose colours vary from one tuber to another. Very large flowers may display red, yellow, pink, purple, or orange tones.
Yes. Every clump reaches approximately 100 cm and carries very large double flowers that become heavy after rain or in wind. Place a stake, ring, or cage beside every tuber at planting so the crown is not pierced later. Use broad soft ties, check them during growth, and loosen when needed. Pinching shoots at 20 or 30 cm creates a more branched plant, but it does not completely replace support in an exposed position. Dinnerplate Mix contains four giant dahlias whose colours vary from one tuber to another. Very large flowers may display red, yellow, pink, purple, or orange tones.
Yes, but use four separate containers or one exceptionally large planter. Every plant needs approximately 45 cm of width and depth, fertile drained mix, and sturdy support. Keep pots in full sun or light partial shade, water deeply when the surface dries, and always empty saucers. Feed moderately, pinch shoots, and remove faded flowers. Containers increase cold exposure; after the first frost, remove tubers, dry them, label their colour, and store them somewhere cool, dry, dark, and frost-free. Dinnerplate Mix contains four giant dahlias whose colours vary from one tuber to another. Very large flowers may display red, yellow, pink, purple, or orange tones.
After frost blackens foliage, cut stems to 10 or 15 cm. Lift every crown with a fork placed away from tuberous roots, gently remove loose soil, and let the surface dry. Attach a label stating Dinnerplate Mix and, when known, the plant’s colour. Store tubers separately in lightly insulating material somewhere cool, dry, dark, and frost-free. Inspect monthly, remove soft tissue with a clean tool, and increase ventilation if condensation appears. Replant only after the final frost. Dinnerplate Mix contains four giant dahlias whose colours vary from one tuber to another. Very large flowers may display red, yellow, pink, purple, or orange tones.
