Description
The Dwarf Dahlia Gardenetta® Orange is a compact and floriferous variety, part of the Gardenetta® series, renowned for its large flowers and remarkable tolerance of powdery mildew. This plant stands out with its fully double flowers, formed of regular rows of petals of intense orange, accentuated by a darker centre. Its almost black foliage offers a striking contrast to the brightness of its flowers. Suitable for borders, the front of flowerbeds, and containers, this Dahlia is a versatile and aesthetic choice for the garden.
Native to the Mexican highlands, the Dahlia genusbelongs to the Asteraceae family and now includes thousands of hybrid varieties. The Dwarf Dahlia Gardenetta Orange is a compact plant that reaches 30 to 45 cm in height and 25 to 30 cm in width. It has an upright habit which does not require staking. The well-formed double flowers are formed of numerous imbricated petals. The heads take the form of large, full, double corollas, made up of numerous imbricated petals, in a bright orange tone, with a deeper shade marking the centre. The well-branched and sturdy stems perfectly support the flowers while the opposite and divided foliage is split into 3 to 5 denticulate lobes. The dark green tinged latter with purplish brown, almost black, enhance the sophisticated character of the plant. The flowering period spans from July to October.
Undemanding, this Dahlia thrives in sunny locations, in rich, fresh, and well-drained soil. To encourage continuous flowering, it is advisable to regularly remove faded flowers.
The Dwarf Dahlia Gardenetta Orange pairs ideally with plants in complementary or contrasting tones. Choose light and graceful perennials and annuals such as coneflowers, Gaura lindheimeri, Cosmos, or even Verbena bonariensis, which bring subtle contrasts in shape and texture. For a more structured effect, consider pairing it with grasses such as Pennisetum villosum or Stipa tenuissima, which will add movement and softness to the display. For subtle contrasts, accompany it with silver foliage such as that of Artemisias or Helichrysum italicum.
Note: Please be aware, our plug plants are professional products reserved for experienced gardeners: upon receipt, transplant and store them under cover (veranda, greenhouse, cold frame...) at a temperature above 14°C for a few weeks before planting them outdoors once the risk of frosts has completely passed.

Planting and care
The Dahlia Gardenetta Orange is easy to grow in all regions. For generous flowering, it is good to follow a few simple rules: plant it in full sun after the last frosts, in rich, cool, and well-drained soil. Stagnant moisture, however, would encourage root rot. Do not hesitate to add compost and sand to the soil if needed. Work the soil deeply and enrich it for example with crushed horn or dried blood. Once planted, water thoroughly once and then continue watering regularly for the first 6 weeks to aid rooting.
Dahlias are sensitive to cold and need to be overwintered. In November, the first frosts cause the foliage to blacken, which is the time to lift them. Carefully dig up the tubercles. Remove as much soil as possible. Allow the foliage to dry so that the tubercles can replenish their reserves. Then cut the stems to 10 cm. Spread your bulbs in a crate on newspaper. Store them in a frost-free, dry, cool, and dark place, such as a frost-free garage or attic. In southern European cosstal regions where there are only a 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 as protection.

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).
