Dahlia ‘Blueberry Cheesecake’ (Dahlia) captivates with its decorative flowers in shades of deep bluish-purple, white, and cream, combined in a refined blend reminiscent of a summer dessert. Its medium green foliage, dense and well-balanced, forms a beautiful backdrop for this unique bloom that renews from July until the first frosts. Vigorous and free-flowering, this variety reaches about 1 to 1.1 m (3.3 to 3.6 ft) in height and makes a remarkable statement in flower beds. Grown as an annual in Quebec, it offers an abundance of elegant flowers, as spectacular in the garden as in floral arrangements.

Plant tubers from March to May, once all risk of frost has passed, about 10 cm (4 in) deep and leaving 50 cm (20 in) between plants. Choose a warm location receiving at least six hours of full sun per day and soil rich in organic matter, fresh, loose, and perfectly drained. Water regularly without waterlogging the soil, then fertilize every two to three weeks with a fertilizer for flowering plants, richer in potassium as buds appear. Stake stems as needed. In the fall, dig up tubers before heavy frosts and store them in a cool, dry, and frost-free place.

Dahlia ‘Blueberry Cheesecake’ is perfect for sunny beds, flower borders, cutting gardens, and large containers on a deck or patio. Its purple, white, and cream hues harmonize beautifully with salvias, cosmos, echinaceas, rudbeckias, and ornamental grasses, in classic or contemporary compositions. Its long, strong stems and excellent vase life allow for the creation of refined bouquets throughout the growing season. Regularly removing faded flowers stimulates the appearance of new buds. The flowers also attract butterflies and bees, contributing to garden biodiversity.

Sowing guide

It all startswith a seed.

Sowing depth

10 cm (4 in)

Sowing period

March to May

Propagation

Divide tubers in spring before planting. Each division must have at least one eye to ensure successful growth.

Growing method

Plant the tubers between March and May, once all risk of frost has passed. Plant them about 10 cm (4 in) deep in fertile, loose, and well-drained soil. Maintain a spacing of 50 cm (20 in) to promote good air circulation. Water after planting, then keep the soil slightly moist without overwatering. Grow in full sun for maximum bloom. Dig up the tubers in the fall before hard frosts and store them in a cool, dry, frost-free place. Plant the tubers from March to May, once all risk of frost has passed, about 10 cm (4 in) deep and with 50 cm (20 in) between plants. Choose a warm location receiving at least six hours of full sun per day, and soil rich in organic matter, cool, loose, and perfectly drained. Water regularly without saturating the soil, then fertilize every two to three weeks with a flowering plant fertilizer, richer in potassium once buds appear. In the fall, dig up the tubers before hard frosts and store them in a cool, dry, frost-free place. Dahlia 'Blueberry Cheesecake' is perfect for sunny beds, flower borders, cutting gardens, and large containers placed on a terrace or patio. Its long, sturdy stems and excellent vase life allow for the creation of refined bouquets throughout the growing season.

Soil and care

The right care,at the right time.

Soil pH

Slightly acidic to neutral

Minimum temperature

32°F (0°C)

Care level

Moderate

Watering

Water regularly to keep the soil slightly moist, but avoid overwatering. Good drainage is essential to protect the tubers. Water regularly without saturating the soil, then fertilize every two to three weeks with a flowering plant fertilizer, richer in potassium as soon as buds appear. Regularly removing faded flowers stimulates the appearance of new buds.

Soil type

The soil should remain moist but not waterlogged. Choose a warm location that receives at least six hours of full sun per day, and soil that is rich in organic matter, moist, loose, and perfectly drained. In the fall, dig up the tubers before hard frosts and store them in a cool, dry, frost-free place. Dahlia 'Blueberry Cheesecake' is perfect for sunny beds, flower borders, cutting gardens, and large containers placed on a deck or patio. Its long, sturdy stems and excellent vase life make it possible to create refined bouquets throughout the growing season.

Fertilization

Apply a balanced fertilizer at the start of growth, then a potassium-rich fertilizer as soon as flower buds appear. Avoid excessive nitrogen, which promotes foliage at the expense of flowers. Water regularly without waterlogging the soil, then fertilize every two to three weeks with a flowering plant fertilizer, higher in potassium once buds appear.

Seasonal care

Plant in spring once all risk of frost has passed and the soil has warmed 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 necessary, to avoid damaging the roots later. Water sparingly at first, then adjust the amount based on foliage growth. Constantly 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 well-opened flowers and use a clean tool to make a clean cut. In autumn, prepare for winter storage of tubers away from frost: dahlias do not overwinter outdoors in Quebec. After the vegetation dies 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. Over the seasons, observe new shoots, soil moisture, and the condition of the stems. A durable label helps locate the plant during its dormant period. Clean tools after cutting diseased parts and remove debris that degrades around the base.

Container growing

A garden,within reach.

Recommended pot size

Minimum 35 to 40 cm (14 to 16 in.) in diameter
Container gardening requires anticipating the volume needed for the roots and the final height of the plant. Choose a stable pot with drainage holes and a suitable growing medium. Leave enough space to respect the recommended depth and spacing, rather than crowding plants to immediately fill the pot. Place the container in the indicated exposure and regularly check the moisture, especially in hot or windy weather. A pot is more exposed to temperature variations than a plant in the ground. Therefore, plan for an overwintering location from the outset that is compatible with the plant's needs and your region's climate. 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 and 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 necessary, to avoid injuring the roots later. Water sparingly at the start, then adapt the watering to the foliage growth. Constantly waterlogged soil around the tubers should be avoided, especially before the first shoots appear. Plan to bring the storage organs indoors, away from frost, for the Quebec winter.

Garden associations

In goodcompany.

Companion plants

To accompany Dahlia ‘Blueberry Cheesecake’, you could consider cosmos, zinnias, or ornamental salvias. Choose companion varieties based on their height, flowering period, and the colors you wish to combine. Most importantly, ensure their light exposure and water needs are suitable for the same location. Maintain enough distance so that leaves don't obscure young shoots and to allow easy access to each plant during maintenance. These pairings are intended to create the garden's aesthetic; they do not guarantee protection against pests or diseases. Adjust the arrangement after observing one growing season.

Frequently asked questions

Your questions,answered.

How to successfully plant Dahlia 'Blueberry Cheesecake'?
Plant in spring once 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 pointing upwards, without breaking the fragile connections. Install a stake at planting if support will be needed, to avoid damaging the roots later. Water sparingly at first, then adjust the amount according to foliage growth. Avoid constantly waterlogged soil around the tubers, especially before the first shoots appear.
What light should I provide for Dahlia 'Blueberry Cheesecake'?
The recommended exposure is full sun. Observe the light in the 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 grows. If in a container, 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 based on the actual moisture of the soil, taking into account rain, heat, and wind. Check below the surface before deciding on new watering: soil that is dry on the surface may still be moist at the root level. Direct water to the base of the plant and let it penetrate, without keeping the plant in saturated soil. Containers generally require more frequent checks because they dry out faster. Make sure their drainage holes remain clear and empty any saucers that retain water. Also adapt care to the plant's cycle: active growth and a dormant period do not require the same amount of water.
What to plan for container growing?
Container gardening requires considering the necessary volume 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 the plants to immediately fill the pot. Place the container in the indicated exposure and regularly check the moisture, especially in hot or windy weather. A pot is more exposed to temperature variations than planting directly in the ground. Therefore, from the outset, plan a wintering location compatible with the plant's needs and your region's climate.
What aftercare should I plan after the growing season?
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 well-opened flowers and use a clean tool to make a clean cut. In autumn, plan for overwintering the tubers away from frost: dahlias do not overwinter in the ground in Quebec. After the vegetation dies back, carefully dig up the clump, let its surface dry, and store it in a cool, airy, and frost-free space. Periodically inspect it for damaged parts.
