Description

Dahlia 'Izarra' is a variety of yellow and orange bicolour star-shaped flowers from the Orchid Dahlia group. Its tapered petals, with more or less curled edges, are randomly bordered or maculated with orange on a bright yellow background. They radiate from the centre of the flower, occupied by a golden yellow heart. The flower, very elegant and flame-like, deserves to be highlighted in the garden or in a bouquet, with light flowers or dark foliage. Semi-hardy, its roots can remain in the ground until temperatures around -8°C (17.6°F).

Dahlias belong to the Asteraceae family and are originally from the high plateaus of Mexico. Currently, the approximately 75,000 horticultural varieties created by humans have invaded, to our greatest pleasure, gardens all over the world. Dahlia 'Izarra' is a deciduous perennial plant with swollen tuberous roots. These tubers, gathered in bundles, produce upright, hollow and ramified stems in spring, as soon as the temperature rises, bearing compound, odd-pinnate leaves with rounded leaflets. The strong, fleshy stems are approximately 70-80cm (28-32in) tall and end in inflorescences called heads, about 7 to 8cm (3in) wide. The foliage of this variety is a bright green colour.

To encourage flowering, make sure to remove faded flowers, or even better, regularly make large colourful bouquets by combining it with other varieties of warm colors. 'Izarra' pairs particularly well with discreet flowers and purple foliage (bugbanes, Heucheras) that won't overshadow the delicacy of its flowering. Offer it companions such as love-in-a-mist, Cosmos, Centaureas, and Scabious that flower at the same time, as well as asters and Buenos Aires verbena.

As a star of borders and cottage gardens, Dahlias confidently accompany the most beautiful flowers but are also appreciated alongside vegetable plants. In Mexico, this tuber was initially cultivated as a root vegetable for consumption. However, its poor taste qualities relegated it to the status of an ornamental plant. Since then, the interest in their beautiful exuberance has never waned.

Tips: When planting, take into account the dimensions for the composition of your flower beds.

Planting and care

The 'Izarra' Dahlia 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 has passed, rich, fresh and well-drained soils are perfect. However, stagnant moisture would promote tuber rot. Do not hesitate to amend the soil with compost and sand if needed. 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. Your dahlia should be covered with about 6cm (2in) of soil. At the end of planting, water once abundantly and then regularly renew this watering for the first 6 weeks to help with rooting. Dahlias are sensitive to cold, so they need to be overwintered.

In November, the first frosts blacken the foliage, it is time to dig them up. Carefully unearth 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 crate on newspaper. Store them protected from frost in a dry, cool and dark place, such as a frost-free garage or an attic. In southern regions, 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 soil with a layer of leaves or straw for protection.

However, note that this Dahlia can remain in the ground until about -8°C (17.6°F), if its stump is well protected by a thick mulch in winter.
