Dwarf Dahlias
Absolutely thrilled when I opened the parcel, which was solidly packed and had been ordered just 48 hours before. The dahlia plug plants are splendid and really sturdy. I immediately repotted them, just like all the plug plants I have received from Promesse de Fleurs since March. It's a shame I can't add photos to show how well they have strengthened after repotting. POTS: outside during the day and brought into the cold greenhouse for the night – they will be planted out in early May. I can't wait to see my border of flamboyant orange dwarf dahlias – what a feast for the eyes it will be!!!

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).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
