Dahlia Samourai

The 'Samurai' semi-cactus Dahlia brings something very new to this category of dahlias, both in structure and in the colour of its inflorescences: large bristly pompoms, composed of delicate cyclamen pink petals and shorter, creamy white petals, all blending into a softer pink centre. This variety will make a big impact in sunny borders and its flowers will allow for bold bouquets. 

Dahlias are tuberous plants from the large family of asters, originally native to the high plateaus of Mexico. At present, the thousands of horticultural varieties have invaded, to our great pleasure, gardens all over the world. These are not very hardy perennials, with fleshy tubers. The 'Samurai', registered in 1990, reaches a height of 1.10m (4ft), depending on the growing conditions, with a spread of 60cm (24in). It is classified among the cactus Dahlias, more specifically the semi-cactus dahlias; this is a horticultural category defined by the shape of the flower. In this group, the coloured ligules of the head curl completely, giving them a characteristic pointed appearance. This variety's flowering begins in July and ends in October-November. The heads measure 18 to 20cm (7 to 8in) in diameter. The habit is bushy and erect, and the highly branched stems are hollow. Its leaves are opposite, pinnately compound, meaning they are divided into 3 or 5 toothed lobes. The leaves and stems are a medium green, quite vivid. 

To extend the flowering period and encourage repeat flowering, take care to remove faded flowers. Even better, regularly cut them to compose alluring colourful bouquets by combining several varieties. 'Samurai' pairs particularly well with white, pink, purple, or crimson blooms, especially those of roses. In a vase, pair it with chrysanthemums and tall asters, for example. In a border, it will perfectly complement white or pink Echinaceas and Cosmos, for example. 

As a star plant for borders and herb gardens, Dahlias confidently accompany the most beautiful flowers, but are also appreciated alongside vegetable plants. In Mexico, this tuberous plant was first cultivated as a root vegetable for consumption. But its poor taste qualities assigned it the rank of an ornamental plant.
