The popularity of the Dahlia continues to increase. The reasons for this devotion are fairly obvious. First of all the skill of the breeders in England, Holland, Germany, Australia and America have produced a range of sizes and colours unmatched in the world of garden flowers.
Equally important is the time of flowering. From the end of July to the first frosts, Dahlias provide large orbs of colour when so many flowers are past their best. Above all the Dahlia is an accommodating plant. It likes a good loam, but will grow almost anywhere. It relishes sunshine, but can still do well in partial shade.
Offering a combination of spicy and warm colours, Dahlia variabilis 'Sunny Reggae' is a delight. Apricot, peach, scarlet, orange, yellow and cream jostle together on flowers that each have their own character. With semi-double flowers, some blooms are decorated with matching collars or in contrasting tones.
Growing to a height of 50 to 60cm (20 to 25in), the plant produces many branching stems. It has a bushy, yet nicely compact habit and the plants do not require staking. These long flowering border plants are easy to grow from seed and make excellent cut flowers. They are suitable for the border or for cultivating in a container for the patio or balcony. They make beautiful potted flowers or charming bouquets. Flowering from the end of July to October they are highly attractive to bees and other pollinating insects.
Dahlia variabilis 'Sunny Reggae' is a Fleuroselect Award Winner.
Dahlias are straightforward to grow from seed. They will flower twelve weeks from sowing until first frosts.
Superb as a cut flower and excellent for creating a statement in displays and herbaceous borders. They are particularly useful for filling in gaps that appear as other plants go to seed.
Seed-raised Dahlias flower well especially towards the autumn. They are generally treated as annuals though they produce a tuber to survive the winter, which can be dug up, stored and replanted the following year.
Sowing: Sow in spring for flowers 12 weeks from sowing.
Fill cells or pots with a free-draining, seed sowing compost, and stand in water so that the compost is thoroughly damp, then allow to drain. It is advisable at this point to use a suitable fungicide prior to sowing, to prevent damping-off disease (available from any garden centre)
Sow the seeds onto the surface of the compost and cover with a layer of vermiculite. Cover the trays with clear or milky polythene to maintain humidity, until the first seedlings are visible. Keep moist at all times.
Germination takes around 7 days at 18 to 20°C (65 to 68°F)
Once germination takes place, remove the cover and keep the seedlings moist.
As soon as the plants are large enough to handle, usually at around three weeks, prick out into 7cm (3in) pots to grow on at 15 to 18°C (59 to 65°F).
Harden off and plant outdoors 30 to 45cm (12-18in) apart in soil with a good nutrient content.
Once the plants are established, a balanced liquid feed can be applied to promote flowering.
Take prevention against slugs – they love Dahlia seedlings!
Water well in summer, Dahlia do not like dry conditions. Feed weekly during the growing season and dead head regularly. Plants are sturdy but may need some support in exposed situations.
Cut flowers early or late in the day when the blooms are almost fully open.
When the foliage begins to die back, cut stems to 15cm (6in) and lift the tubers. Store in straw, wood shavings, or vermiculite in a frost-free place. Divide tubers in spring and plant out once danger of frost has passed. The soil temperature should be at least 13°C (55°F). If planted before this temperature is reached may rot before they can sprout.
Native to Central America, the genus Dahlia was named in honour of Anders Dahl (1751-1789), an 18th century Swedish botanist. He was a pupil of Linnaeus. (the man responsible for the binomial system of naming plants, where the genus is followed by the species.)
Andreas Dahl regarded it as a vegetable rather than a garden flower, but interest switched from the edible tubers to the blooms when the first varieties with large, double flowers were bred in Belgium in 1815.
Although dahlias were discovered in the 16th century by Spanish conquistadors, not until 1872 was a box of tubers sent to Holland. Within a few years nearly every colour we now admire had been introduced and Victorian catalogues listed hundreds of varieties.
From just a handful of original species Dahlias have been hybridised over the centuries into an amazingly diversified genus, with plant sizes from 30cm to 200cm (1 to 7ft) tall, and flowers in almost any colour imaginable from 5cm to 30cm (2 to 12in) wide.
Fleuroselect is the international organisation for the ornamental plants industry. Its main activities include the testing, protecting and promoting of new flower varieties. Membership includes breeders, producers and distributors of ornamental varieties. Fleuroselect is run by the members, for the members. A small secretariat operates from the organisational headquarters currently based in Noordwijk, The Netherlands.
In order to support and stimulate the development of new ornamental varieties, Fleuroselect conducts trials of new varieties entered by members on approximately 20 private trial grounds spread across Europe. Both indoor and outdoor trials can be conducted. Through the trials, the newness, the practical use, the quality and the exclusivity of the entries are determined. Genuinely new varieties receive recognition either as Fleuroselect Novelties or Gold Medal winners. The Fleuroselect Gold Medal is awarded to innovative varieties that clearly surpass the limits in breeding and beauty. This symbolises excellence in breeding.
Many awarded varieties are widely supported and distributed by Fleuroselect members. The organisation also promotes the winners by way of press releases and displays at trade fairs and in gardens all over the world. Professional growers and hobby gardeners all over the world recognise the Fleuroselect awards as certificates of exceptional merit.
