Description
The Dahlia 'Big Brother' stands out, in the garden or in a cut flower arrangement, with its giant flowers in a palette of golden yellow, peach, and orange. They bloom from summer until autumn. Its apricot-gold colour distinguishes itself in flower beds or the dedicated cut flower patch. Its voluminous, luminous, and warm flower wins over gardeners, as well as florists.
Dahlia belongs to the Asteraceae family and is native to the high plateaus of Mexico and Central America. This tubercle-bearing plant is a frost-tender perennial; its stump will need to be dug up and overwintered frost-free.
'Big Brother' is a horticultural hybrid classified in the giant decorative dahlias group, or "dinner plate" dahlias, characterised by very double heads, often exceeding 20 cm in diameter. This cultivar is a giant informal decorative, with flowers 20 to 25 cm in diameter, borne on sturdy stems. The plant has an upright, well-ramified habit, reaching a height of between 90 and 120 cm and a width of 45 to 60 cm, depending on growing conditions. The medium green foliage consists of ovate to lanceolate leaflets, more or less dentate, forming a dense mass that showcases the flowers. The thick stems benefit from being staked in windy locations.
The very double flowers are filled with slightly undulate or fringed petals at the edges, in shades ranging from buttery yellow to intense gold, warmed with apricot and caramel hues towards the centre. Flowering lasts from July to October, or even until the first frosts in mild climates.
To extend the flowering period and encourage repeat flowering, be sure to remove spent flowers. Cut them regularly to create magnificent colourful cut flower arrangements by combining several varieties.
The Dahlia 'Big Brother' is spectacular yet elegant, with its very large flowers that catch the eye without being garish. This variety has a modern romantic style, ideal for boho chic bouquets, where it naturally plays the role of the 'star' flower. You can pair it with dahlias in powdery tones like 'Trustfull', with delicately pink-tinged petals, or 'Crème de Cognac', cream washed with raspberry pink and a more purplish reverse. To enhance the boho spirit, you can slip in a few stems of 'Labyrinth', with its twisted apricot-pink petals. A more contrasting dahlia like 'Crème de Cassis', with plum and patinated mauve hues, will accentuate its chic side in a display that remains soft and very contemporary.
Introduced to Europe in the late 18th century, dahlias were first cultivated as vegetable plants, their tubercles having been tested as a vegetable and even as a coffee substitute, before their immense ornamental potential established them in gardens.

Planting and care
Plant your 'Big Brother' dahlias on a fine weather day in deeply worked soil enriched, for example, with ground horn or dried blood. Place your tubercle and crumble the soil well to fill in without air pockets. Your dahlia should be covered with 6 cm of soil. At the end of planting, pour a litre of water. Water regularly during the first 6 weeks to help with rooting.
Dahlias are sensitive to cold, they need to be overwintered. In November, the first frosts will blacken the foliage, it's time to lift them. Dig up the tubercles carefully. Remove as much soil as possible. Allow the foliage to dry, so the tubercle can replenish its reserves. When the foliage is dry, cut the stems to 10 cm from the tubercle. Spread your bulbs in a crate on newspaper. Store in a frost-free, dry, cool, and dark place.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
