Description

The 'Karma Irene' Decorative Dahlia offers large waterlily-like flowers with a vibrant colour, intermediate between orange and red, carried on particularly sturdy stems ideal for creating bouquets. The Karma series of Dahlias, initially developed for cut flowers, offers medium-sized, brightly coloured varieties that also have a place in borders and make beautiful potted plants. 'Irene' flowers quite early in the season, and its freshly picked flowers can last up to 7 days in a vase. 

 

Dahlias belong to the large family of asters and are originally from the high plateaus of Mexico. At present, the approximately 25,000 horticultural varieties obtained by humans have invaded gardens all over the world, much to our delight. Dahlias are classified according to the shape of their heads. 'Karma Irene' is a Decorative Dahlia with waterlily-like flowers. The inflorescences are composed of several rows of almost flat outer ligules, barely curled downwards. The heads are opulent and measure up to 14 cm (6in) in diameter. The ligules are a very bright orange, tending towards red, perfectly uniform. The tightly packed centre of the flower is composed of small petals with a golden yellow base. The plant will reach a height of 90 cm (35in) and a width of 50 cm (20in). It has a bushy and compact habit, and the strength of its stems does not require any staking. Its leaves are deeply denticulate. The particularly long flowering period of this variety begins at the end of June and ends in October-November, if care is taken to remove faded flowers or make frequent bouquets.

 

Today, Dahlias are essential in gardens. They were initially cultivated in Mexico as a root vegetable. Their poor taste qualities quickly relegated them to the status of ornamental plants, but they are still welcome in vegetable gardens to bring a splash of colour among the vegetables. 'Karma Irene' particularly complements white, red, and bright blue flowers.

Planting and care

Dahlia 'Karma Irene' is easy to grow in all regions. For abundant flowering, it is good to follow a few simple rules: plant the tubers in full sun as soon as the last frost is over. Rich, damp, and well-drained soil is perfect. However, waterlogging would promote tuber rot. Feel free to amend the soil with compost and sand if necessary. Work the soil deeply and enrich it, for example, with bonemeal.  Place your tuber and crumble the soil well to fill without air pockets. Your dahlia should be covered with about 6 cm (2in) of soil. At the end of planting, water generously once and then regularly repeat this watering during the first 6 weeks to help with rooting.

 

Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frost blackens the foliage, which is the time to dig them up. Carefully remove the tubers, removing as much soil as possible. Let the foliage dry so that the tubers can replenish their reserves. Then cut the stems to 10 cm (4in). Spread your bulbs in a box on newspaper. Store them in a frost-free, dry, cool, and dark place, such as a frost-free garage or attic, for example. In warmer regions, or areas close to the coast, where there are few frosty days per year, it is possible to leave them in place. In this case, simply cover the ground with a carpet of leaves or straw for protection.
