Dahlia Ball 'High Fidelity' (1 tuber)
Dahlia × pinnata
Dahlia pompon ‘High Fidelity’ (Dahlia × pinnata ‘High Fidelity’) is an elegant tuberous perennial distinguished by its perfectly spherical, intense raspberry-red flowers, subtly lighter at the petal tips. Short, curved, and tightly imbricated, these petals form the dense, regular texture typical of pompon dahlias. From July to October, it blooms generously above dark green foliage on plants reaching about 90 cm (35 in) in height. This variety adds structure, vibrancy, and refinement to summer plantings. Not hardy in Quebec, it must be overwintered in a frost-free location. Plant the tuber in spring, when all risk of frost has passed, about 10 cm (4 in) deep in rich, loose soil enriched with compost and perfectly drained.

Dahlia pompon 'High Fidelity' (Dahlia) is an elegant tuberous perennial distinguished by its perfectly spherical, intense raspberry-red flowers, subtly lightened towards the tips of the petals. Short, curved, and tightly imbricated, these petals form a dense and regular texture typical of pompon dahlias. From July to October, the blooms generously renew themselves above dark green foliage on plants reaching approximately 90 cm (35 in) in height. This variety brings structure, radiance, and refinement to summer arrangements. Not hardy in Quebec, it must be overwintered in a frost-free environment.
Plant the tuber in spring, when all risk of frost has passed, about 10 cm (4 in) deep in rich, loose soil, enriched with compost, and perfectly drained. Choose a well-ventilated location receiving at least six hours of direct sunlight per day, then space the plants 30 to 40 cm (12 to 16 in) apart. Water lightly until sprouts appear, then regularly to keep the soil moist without waterlogging it. Pinch back young stems to encourage branching and apply a potassium-rich fertilizer once buds begin to form. Dig up the tuber after a light frost and store it in a cool, dry, and frost-free place.
Dahlia 'High Fidelity' is ideal for colorful borders, sunny beds, large containers, and cut flower gardens. Combine it with salvias, white cosmos, echinaceas, Verbena bonariensis, and ornamental grasses to create vibrant and well-balanced scenes. Its long stems produce excellent cut flowers, highly prized for their impeccable shape, vibrant color, and remarkable vase life. The flowers also attract various pollinators throughout the growing season. Regular harvesting and removal of spent blooms help maintain abundant flowering until the first frosts.

Propagation
Divide the tubers in the spring when each section has at least one viable eye. This method faithfully preserves the characteristics of this variety.
Growing method
Plant in spring when all risk of frost has passed and the soil has warmed up sufficiently. Choose a sunny spot, sheltered from strong winds, in fertile, well-drained soil. Arrange the tuberous roots with their crown and buds facing upwards, without breaking the fragile attachments. Install a stake at planting if support will be needed, to avoid damaging the roots later. Water sparingly at first, then adjust watering to foliage growth. Consistently waterlogged soil around the tubers should be avoided, especially before the first shoots appear. During summer, water at the base when the soil dries out and tie up stems as needed with flexible ties. Regularly remove faded flowers to encourage the formation of new buds. For bouquets, choose fully open flowers and use a clean tool to make a clean cut. In autumn, plan for winter storage of the tubers away from frost: dahlias do not overwinter in the ground in Quebec. After vegetation ends, carefully dig up the clump, let its surface dry, and store it in a cool, airy, frost-free space. Inspect it periodically to identify any damaged parts.

Watering
Water regularly to maintain evenly moist soil without overwatering. An organic mulch helps retain moisture and reduces watering needs during hot spells. Before watering, check the moisture level below the surface with your finger rather than following a fixed schedule. Recent rain, wind, and container growing can quickly alter watering needs.
Soil type
Prioritize humus-rich soil that retains moisture while allowing excess water to drain. Check drainage after rain: water must be able to leave the root zone. Work the soil when it is dry to avoid compacting it. Adapt amendments to its actual texture. For potted plants, use appropriate potting soil and a pot with drainage holes. Keep these openings clear and avoid any water accumulation in the saucer.
Fertilization
Before adding fertilizer, consider the richness of your soil and any previous applications. A soil analysis can help you choose the most beneficial amendments. If you use a fertilizing product, follow the dosage, frequency, and application method indicated on the packaging. Avoid concentrated applications directly on the roots. Do not over-apply products: an excessive amount of fertilizer does not guarantee better growth or more abundant flowering.
Seasonal care
Plant in spring when all risk of frost has passed and the soil has warmed sufficiently. Choose a sunny location, sheltered from strong winds, in fertile, well-drained soil. Arrange the tuberous roots with their crown and buds pointing upwards, without breaking the fragile attachments. Install a stake at planting if support will be necessary, to avoid damaging the roots later. Water sparingly at the beginning, then adjust watering based on foliage growth. Constantly waterlogged soil around the tubers should be avoided, especially before the first shoots appear. During the summer, water at the base when the soil dries out and tie the stems as needed with flexible ties. Regularly remove faded flowers to encourage the formation of new buds. For bouquets, choose fully open flowers and use a clean tool to make a clean cut. In the fall, plan for overwintering the tubers in a frost-free environment: dahlias do not overwinter in the ground in Quebec. After the vegetation has died back, carefully dig up the clump, let its surface dry, and store it in a cool, airy, frost-free place. Inspect it periodically for damaged parts. Throughout the seasons, observe new shoots, soil moisture, and the condition of the stems. A durable label helps locate the planting during its dormancy. Clean tools after cutting diseased parts and remove debris that degrades around the base.
Container growing
A garden,within reach.
Recommended pot size
35 cm (14 in)
Container gardening requires you to plan for the necessary volume for the roots and the final height of the plant. Choose a stable pot with drainage holes and a substrate suitable for planting. Leave enough space to respect the recommended depth and spacing, rather than crowding the plants to fill the pot immediately. Place the container in the recommended exposure and regularly check the moisture, especially in hot or windy weather. A pot is more exposed to temperature variations than planting in the ground. Therefore, plan from the outset for an overwintering location compatible with the needs of the plant and the climate of your region. Plant in spring when all risk of frost has passed and the soil is warm enough. Choose a sunny spot, sheltered from strong winds, in fertile and well-drained soil. Arrange the tuberous roots with their crown and buds facing upwards, without breaking the fragile attachments. Install a stake at the time of planting if support will be necessary, to avoid damaging the roots later. Water sparingly at first, then adjust the watering to the foliage growth. Constantly waterlogged soil around the tubers should be avoided, especially before the appearance of the first shoots. Plan to store the tubers in a frost-free place for the Quebec winter.

Garden associations
In goodcompany.
Companion plants
To accompany Dahlia pompon 'High Fidelity', you could consider cosmos, zinnias, or ornamental salvias. Choose companion varieties based on their height, flowering period, and the colors you wish to combine. Above all, ensure that their exposure and water needs are suitable for the same location. Maintain enough distance so that leaves do not obscure young shoots and to easily access each plant during maintenance. These associations serve to compose the garden's décor; they do not guarantee protection against pests or diseases. Adjust the layout after observing one growing season.
Frequently asked questions
Your questions,answered.
How to successfully plant ‘High Fidelity’ Pompon Dahlia?
Plant in spring when all risk of frost has passed and the soil is sufficiently warm. Choose a sunny location, sheltered from strong winds, in fertile, well-drained soil. Arrange the tuberous roots with their crown and buds facing upwards, without breaking the fragile attachments. Install a stake at the time of planting if support will be needed, to avoid damaging the roots later. Water sparingly at the start, then adjust watering to the foliage growth. Constantly waterlogged soil around the tubers should be avoided, especially before the appearance of the first shoots.
What light do I need for Dahlia pompon 'High Fidelity'?
The recommended exposure is full sun. Observe the light in your chosen location in the morning and afternoon, as the shade from trees or buildings changes throughout the day. Also, consider nearby plants: their foliage can obscure a young plant as it develops. For container plants, place the pot where you can move it if conditions become too hot or too shady. Suitable exposure must go hand in hand with appropriate soil and watering. If you move a plant started indoors to the outdoors, gradually accustom it to garden conditions to avoid too abrupt a transition for young leaves.
How to adjust watering?
Water according to the actual moisture level of the soil, taking into account rain, heat, and wind. Check below the surface before deciding on a new watering: soil that is dry on the surface can still be moist at the root level. Direct water to the base of the plant and allow it to penetrate, without keeping the plant in saturated soil. Containers generally require more frequent checks because they dry out faster. Ensure that their drainage holes remain clear and empty any water from saucers. Also, adapt care to the plant's cycle: active growth and a resting period do not require the same amount of water.
What to plan for container growing?
Container gardening requires planning for the volume needed for the roots and the plant's final height. Choose a stable pot with drainage holes and a substrate suitable for planting. Leave enough space to respect the recommended depth and spacing, rather than crowding plants to fill the pot immediately. Place the container in the recommended exposure and regularly check for moisture, especially in hot or windy weather. A pot is more exposed to temperature variations than a plant in the ground. Therefore, plan for a winter storage location compatible with the plant's needs and your region's climate from the outset.
What care should be planned after the growing season?
During summer, water at the base when the soil dries out and tie stems as needed with flexible ties. Regularly remove faded flowers to encourage the formation of new buds. For bouquets, choose fully open flowers and use a clean tool to make a clean cut. In autumn, plan for winter storage of tubers in a frost-free environment: dahlias do not overwinter in the ground in Quebec. After the growing season ends, carefully dig up the clump, allow its surface to dry, and store it in a cool, aerated, and frost-free space. Inspect it periodically to check for damaged parts.
