‘Dahlegria Neon Flair’ Dahlia (Dahlia × hortensis) Dahlegria Neon Flair dahlia belongs to the Mignon group, recognized for single flowers with open centres. Each flowerhead approximately 10 cm wide presents one row of deep pink petals fading toward pale tips, with yellow splashes surrounding a brown and yellow central disc. Luminous flowers stand against bronze to dark purple foliage that remains ornamental well before flowering. The upright clump reaches 70 cm tall and 50 cm wide, blooming from midsummer until frost. Van Noort supplies one No. 1 tuber of this compact pollinator dahlia for containers and front borders, where foliage and flowers create continuous colour contrast.

Plant the tuber in spring after the final frost once soil has warmed. Set it horizontally 10 cm deep with the bud facing upward, leaving 50 cm around the developing clump. Choose a sheltered position in full sun with fertile humus-rich soil that remains moist yet drains freely. Water lightly before emergence, then deeply at the base whenever the surface dries. Add mature compost at planting and apply fertilizer moderate in nitrogen and richer in potassium from bud formation. Pinch young shoots to build a dense silhouette and remove faded flowerheads regularly to maintain flowering, keep the open centres visible, and reduce untidy seed development.

Place Neon Flair toward the front or middle of a border, in a pollinator garden, or in one large stable container. Dark foliage pairs with white sweet alyssum, pink gauras, blue salvias, verbenas, and golden grasses, while single flowers give bees, butterflies, and hoverflies direct access. Harvest a few fully open stems without removing every resource from the garden. In colder Canadian regions, after the first frost blackens foliage, cut stems, lift the tuber carefully, allow its surface to dry, and keep it labelled somewhere cool, dry, dark, and frost-free until the following spring. Inspect monthly and retain only firm viable tissue.

Frequently asked questions

Frequently asked questions

When should Neon Flair be planted in colder Canadian regions?
Wait until after the final frost and until soil has warmed, generally from May to early June. Set the tuber horizontally 10 cm deep.
Why does it attract pollinators?
Single flowers leave the central disc visible. Bees, butterflies, and hoverflies can therefore reach pollen and nectar directly while the plant is flowering.
Can it be grown in a container?
Yes. Place the tuber in a stable container at least 40 cm wide, freely drained, filled with fertile potting mix, and positioned in full sun.
Does this cultivar need staking?
Its 70 cm height limits risk, although a discreet stake remains useful in windy locations or when the clump carries many rain-weighted flowers.
How should the tuber be stored over winter?
After the first frost, cut stems, lift the tuber, dry its surface, and keep it labelled somewhere cool, dry, dark, and frost-free.

Wildlife and pets

Wildlife & precautions

Reported toxicity

Yes

Supporting wildlife

Single flowers with open discs make pollen and nectar accessible to bees, hoverflies, and butterflies during summer flowering. Extend the border’s value by pairing this dahlia with sweet alyssum, salvias, and verbenas blooming before or after it. Avoid insecticides on flowers and provide a shallow dish of clean water nearby.
