Description

Dahlia 'Pure Happiness' bears unique flowers. The petals are white with a yellow base and pink tips. They are carried by strong stems, which are perfect for making bouquets. It is remarkably easy to cultivate. This lovely bush blooms throughout summer and will brighten up flower beds and vegetable plots.

 

Dahlias belong to the Asteraceae family and are originally from the high plateaus of Mexico. There are currently thousands of horticultural varieties that have conquered gardens worldwide. They are tender perennials with fleshy tubers.

Dahlias are classified according to the shape of their flowers. 'Pure Happiness' is classified as a decorative dahlia with small flowers. They are characterised by ligules (or petals) arranged regularly in a spiral, which can be bent towards the stem or fringed.

The flower heads of 'Pure Happiness' measure approximately 11cm (4in) in diameter. The ligules are white, slightly tinged with pink, and tinted yellow at the base. The flowering period extends from July until the first frost. The bushy and upright plant will reach approximately 1m (3ft) in height, with a width of 50 to 60cm (20 to 24in). The stems are hollow and therefore fragile in windy conditions. The green leaves are opposite, divided into 3 or 5 leaflets.

Remove faded flowers to encourage new blooms. You can use cut flowers to make colourful bouquets, combining them with other varieties.

Plant several dahlias in a flower bed or plant several varieties in a vegetable patch. The flowers of Dahlia 'Pure Happiness' will blend beautifully with those of D. 'Bora Bora' or D. 'Bishop of Leicester'.

Decorative dahlias pair well with gauras with white or pink flowers and cleomes with a delicate appearance. Echinaceas and the white-flowered Salvia microphylla 'Gletsjer' are ideal companions for this variety, creating a soft and gentle flower bed.

Planting and care

It is easy to grow in all regions. Plant in spring as soon as the last frost has passed. For abundant flowering, plant the tubers in full sun in rich, moist but well-drained soil. Stagnant moisture causes tuber rot. Amend the soil with compost and sand, if necessary. Work the soil deeply and enrich it, for example, with crushed horn or dehydrated blood. Place your tuber and crumble the soil well to fill without air pockets. Cover with about 6cm (2in) of soil. At the end of planting, water once abundantly and then repeat this watering regularly during the first 6 weeks to help with rooting. 

Dahlias are sensitive to cold, so they need to be overwintered. Dig the tubers up when the first frost has blackened the foliage. Carefully remove the tubers. Remove as much soil as possible. Let the foliage dry so that the tubers can replenish their reserves. Then cut the stems to 10cm (4in). Spread your bulbs in a box lined with newspaper. Store them in a frost-free, dry, cool, and dark place, such as a garage or attic. In mild regions without frost, or those close to the coast, it is possible to leave them in place. In this case, simply cover the ground with a carpet of leaves or straw for protection.

Pinch the stems early (from the 3rd or 4th week after planting) to make your dahlia more compact and branched, and therefore more resistant to bad weather (wind, rain). To do this, use your nails to cut the terminal shoots just above the leaves. If you choose not to pinch out, there is always the option of staking, but the aesthetic result may not be the best.

Watch out for slugs and snails. They are very fond of these young shoots.
