Joel's Favourite Dahlia (Dahlia pinnata ‘Joel's Favourite’) is an elegant tuberous perennial distinguished by its large, fully double magenta-pink flowers enriched with deep purple undertones and highlighted by a bright golden centre. Their rich colour contrasts beautifully with dense, vigorous dark green foliage. From July through October, this vigorous variety produces an abundance of blooms on sturdy plants reaching 90 to 110 cm (36 to 43 in) tall. Fast growing and highly floriferous, it brings vibrant colour, depth, and sophistication to summer landscapes. Not hardy in Canada, this Zone 10 variety should be overwintered in a frost-free location to preserve the tubers for the following season.
Plant the tuber in spring after all danger of frost has passed and the soil has thoroughly warmed, approximately 10 to 12 cm (4 to 5 in) deep. Choose a location in full sun, preferably sheltered from strong winds, with rich, loose, humus-rich, evenly moist, well-drained soil. Space plants 40 to 50 cm (16 to 20 in) apart and water regularly without allowing the soil to become waterlogged. Feed every two to three weeks with a fertilizer high in potassium while avoiding excessive nitrogen. Remove spent blooms regularly to encourage continuous bud production. Lift the tubers before the first hard frost and store them in a cool, dry, frost-free location until spring.
Joel's Favourite Dahlia (Dahlia pinnata ‘Joel's Favourite’) is an excellent choice for colourful garden beds, flowering borders, large containers, and cutting gardens. Pair it with cosmos, salvias, Verbena bonariensis, and ornamental grasses to create elegant plantings where its rich magenta blooms become the focal point. The fully open flowers have outstanding vase life and are perfect for creating luxurious summer bouquets. They also attract bees, butterflies, and many other pollinating insects throughout the season. Regular harvesting and deadheading will encourage continuous flowering until the first frost.
Sowing guide
It all startswith a seed.
Sowing depth
10 to 12 cm (4 to 5 in)
Sowing period
Spring
Propagation
Divide the tubers in spring, ensuring each division has at least one viable growing eye. This preserves the characteristics of the cultivar.
Growing method
Plant the tubers in spring after all danger of frost has passed and the soil has thoroughly warmed. Plant 10 to 12 cm (4 to 5 in) deep, spacing tubers 40 to 50 cm (16 to 20 in) apart in rich, loose, well-drained soil. Choose a location in full sun, preferably sheltered from strong winds, for abundant flowering. Water regularly without allowing the soil to become waterlogged and fertilize throughout the growing season. Remove spent blooms regularly to encourage continuous bud production. Lift the tubers before the first hard frost and store them in a cool, dry, frost-free location over winter.
Soil and care
The right care,at the right time.
Soil pH
Slightly acidic to neutral
Minimum temperature
5°C (41°F)
Care level
Intermediate
Watering
Water regularly to keep the soil evenly moist without overwatering. Reduce watering before lifting the tubers in autumn.
Soil type
Rich, loose, humus-rich, well-drained soil that remains evenly moist without becoming waterlogged. Avoid heavy, poorly drained soils.
Fertilization
Apply a fertilizer high in potassium every two to three weeks during active growth. Avoid excessive nitrogen, which encourages foliage rather than flowers.
Seasonal care
Remove spent blooms regularly to prolong flowering. Water deeply during hot weather without overwatering. Fertilize every two to three weeks throughout the growing season. Lift the tubers before the first hard frost and store them in a cool, dry location over winter.
Container growing
A garden,within reach.
Recommended pot size
35 to 45 cm (14 to 18 in)
Container growing requires you to provide sufficient volume for the roots and the plant's final height. Choose a stable pot with drainage holes and a suitable growing medium. Leave enough space to respect the recommended depth and spacing, rather than cramming plants together to fill the pot immediately. Place the container in the indicated exposure and regularly check for moisture, especially in hot or windy weather. A pot is more exposed to temperature variations than planting directly in the ground. Therefore, plan for a wintering location from the outset that is compatible with the plant's needs and your region's climate. 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 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 start, then adjust watering to foliage growth. Consistently soggy soil around the tubers should be avoided, especially before the first shoots appear. Plan to bring storage organs indoors, away from frost, for the Quebec winter.
