I am disappointed with my order. Instead of receiving cactus dahlias, I received superfine mix cacti (11b174f).

Description

Dahlia 'Giant Hybrids Mixed' is a stunning collection that features extra-large single, semi-double and fully double blooms in a wide array of bright shades. Excellent for cutting! Dahlias are popular, easy to grow plants that bloom prolifically from July until the first frosts. This giant selection is perfect planted en masse in borders or to the back of summer bedding schemes.

Dahlias belong to the Asteraceae family and are native to Mexico. Nowadays, some 20,000 horticultural varieties are grown in gardens all over the world. 'Giant Hybrids Mixed' produces very tall, erect plants that grow to approximately 1.50 m in height and 50 cm in width. They may need support to prevent the stems from tipping under the weight of the blooms. The flowering period takes place from July to October. The single, semi-double, fully double or pompom-like corollas are made up of several layers of ray flowers in a variety of bright shades including yellow, orange, red, pink and dark purple, surrounding a yellow central disc. The stems are well branched and hollow, bearing opposite leaves that are subdivided into 3 or 5 toothed lobes. Both leaves and stems are bright green to dark green. To encourage repeat flowering and extend the flowering period, take care to remove faded flowers regularly. Better still, cut the flowers regularly to create beautiful, colourful arrangements.

Dahlias are great for creating patches of colour in summer beds and borders. They combine well with Echinacea, Helenias, Cosmos and Asters or with the soft, feathery plumes of ornamental grasses such as Miscanthus.

Planting and care

Sow in February-March, in seed trays or pots filled with sowing mix. Bury the seeds under 1.5 mm of fine soil. Place in a propagator or somewhere warm, at a temperature of 18 to 20°C. Germination takes 7 to 21 days. Transplant the seedlings into individual pots when they are strong enough to be handled, taking care not to damage the roots. Harden the plants off gradually and plant them out when all risk of frost is over, leaving 30 cm between each plant.

Dahlias enjoy full sun and rich, cool, well-drained soil. Stagnant humidity can cause the tubers to rot. If necessary, amend the soil with compost and sand. Dig over the plot thoroughly and enrich the soil with hoof and horn meal fertilizer. After planting, water once abundantly and repeat this regularly for the first 6 weeks to help root development.

Dahlias are sensitive to cold temperatures and must be overwintered indoors. In November, when the first frosts blacken the foliage, dig up the tubers carefully. Clean off as much soil as possible. Allow the foliage to dry, so that the tubers can rebuild their food reserves. Then cut the stems back to about 10 cm. Spread your bulbs in a crate on newspaper. Store them in a dry, cool, dark place, such as a garage or attic, sheltered from frost. In warmer climates, Dahlias can be left in place and protected under a layer of mulch (leaves, straw etc.)
