Description
The Coreopsis grandiflora 'Louis d'Or' is a robust variety of Tickseed, also known as Coreope or Coreopside. This beautiful perennial is distinguished by its fluffy double daisy-like flowers, in a vibrant golden yellow, which bloom throughout the summer on a tall and elegant plant, both in flower beds and in bouquets. This undemanding and generous perennial thrives in the sun, in a light and well-drained soil.
The Coreopsis grandiflora belongs to the Asteraceae family. It is native to North America, from California to New Mexico (all states to the east), and up to the Great Lakes. 'Louis d'Or' is a cultivar with double heads, whose rounded and slightly loose growth habit is very similar to that of the single flower type. This rhizomatous perennial plant forms a shrub that reaches a height of 60 to 80 cm (24 to 32in), with a diameter of 40 to 50 cm (16 to 20in), which may sometimes require staking in windy or rainy climates. The flowering period is from June to August. The solitary heads are 6 cm (2in) in diameter and are borne on slightly hairy stems. The foliage, a beautiful intense green, is deciduous. The leaves, opposite, lanceolate, entire, sometimes incised at the base, almost sessile (without petiole), measure 10 cm (4in) in length. This perennial spreads quite rapidly through rhizomes.
The 'Louis d'Or' Tickseed is not fond of winter humidity and heavy soils. This plant requires full sun to flower well. The Coreopsis grandiflora is a versatile perennial. It will thrive in a raised bed or on a slope alongside wallflowers, Damask nigellas, and wild flax, in an herbaceous border with Teucrium chamaedrys, or x lucidrys, thyme, and santolines. It is perfect for greening a meadow or a slightly wild area of the garden. This plant blooms continuously from the first year. For a beautiful summer display, whether in the ground or in a large pot with very little water, it can be paired with Calamintha glandulosa and Nepeta 'Dawn to dusk'. Lastly, it makes a lovely flower for summer bouquets, and brings sunshine indoors.

Planting and care
The grandiflora coreopsis plant and its varieties don't do well in winter humidity and heavy soils. To thrive, they need full sunlight and a well-draining, slightly acidic, neutral or slightly chalky soil that is light and porous, such as gravelly or sandy soil. This kind of soil helps the plant produce beautiful flowers and live a long time. It's important to remove faded flowers regularly and promote autumn reblooming in July to encourage more flowering and prolong the plant's lifespan. You can also divide exhausted shrubs every three years to keep them healthy.

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.
