Description
Coreopsis grandiflora 'Sonnenkind', is a variety of Tickseed. This selection is distinguished by its large, bright yellow daisies with red markings in the centre, which bloom throughout the summer, and its compact habit that makes it suitable for the front of borders and herbaceous borders. Elegant and easy to grow, even in containers, it only requires sun and light soil to thrive.
Coreopsis grandiflora belongs to the Asteraceae family. It is native to North America, from California to New Mexico (all states to the east) and the Great Lakes. 'Sonnenkind' is a cultivar with single heads, shorter and more compact than the type. This rhizomatous perennial plant forms a basal tuft, rounded like a basket, with a spread of 40 cm (16in) in all directions. The flowering period takes place from June to August. The solitary heads, 6 cm (2in) in diameter, are on slightly hairy stems. The foliage, a beautiful, intense green, is deciduous. The leaves, lanceolate, opposite, entire, sometimes incised at the base, almost sessile (without petiole), measure 10 cm (4in) in length. This perennial spreads quite rapidly through rhizomes.
The 'Sonnenkind' Tickseed dislikes winter humidity and heavy soils. To flower well, this plant requires full sun. It prefers light, moist, porous, gravelly or sandy soil, always well-drained, slightly acidic, neutral, or alkaline. Under such conditions, these plants flower and live for a long time. To encourage reblooming, it is preferable to remove faded flowers regularly and then in July to promote autumnal reblooming. This operation will also extend the life of the plant.
Coreopsis grandiflora is a versatile perennial. It will be happy in a rock garden or on a slope with wallflowers, love-in-a-mist, wild flax in an herbaceous border alongside Teucrium chamaedrys or x lucidrys, thyme, and cotton lavender. It is perfect for naturalising a meadow or a slightly wild area of the garden. This plant blooms continuously from the first year in a pot or container. For a beautiful summer display, both in the ground and in large pots, with very little water, it can be paired with Calamintha glandulosa and Nepeta 'Dawn to dusk'. It is also a lovely flower for summer bouquets, like a little sun in the house.

Planting and care
The 'Sonnenkind' coreopsis plant doesn't like winter moisture and heavy soils. It needs full sun to grow well. To thrive, the plant prefers light, fresh, and well-drained sandy or gravelly soil that's slightly acidic or neutral. This allows the plant to produce beautiful flowers and live a long life. To encourage reblooming, remove faded flowers regularly and promote autumn reblooming in July. Doing this will help the plant last longer. To revitalise exhausted clumps, divide them about every 3 years.

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.
