Description

The large-flowered tickseed Esrly Sunrise is a pretty fabulous, new variety of Coreopsis grandiflora: this perennial plant blooms 3 weeks earlier than other varieties, and its pompom-like flowers which are of substantial size, dry out and disappear without the help of any gardener. Packed with bright yellow petals surrounding a honey-brown eye, the flowers bloom continuously until autumn, like many little suns on top of bushy, neat-looking plants. Awarded in the USA for its numerous qualities, Early Sunrise is a variety that is just as easy to grow as the more classic tickseeds. Provide it with sun and ordinary, well-drained soil.

Coreopsis grandiflora belongs to the family  Asteraceae. It is native to North America, California, and is present from New Mexico (all the states to the east) to the Great Lakes. 'Early Sunrise' is a particularly abundantly flowering American cultivar that bears fully double flower heads and displays a denser, more compact growth habit. This rhizomatous perennial forms a 25 cm high basal mound, 40 to 45 cm across. It flowers from early June to early October, usually two years after sowing, but sometimes as early as the first year from sowing. The solitary flower heads, 5-6 cm across, are borne at the end of slightly hairy stems, 45-50 cm in height. The foliage, which is a beautiful intense green, is deciduous: meaning it disappears in winter. The leaves are opposite, lanceolate, simple, sometimes incised at the base, almost stalkless (without a petiole) and are about 10 cm long. This perennial spreads, quite rapidly, through its rhizomes. In the garden, choose a sunny spot with rich, well-drained soil.

The only thing that Coreopsis 'Early Sunrise’ does not tolerate are heavy soils, especially ones that are too moist in the winter. This plant requires full sun to flower well. This versatile perennial will thrive in raised beds or on an embankment with wallflowers, love-in-a-mist and pale flax, in a herbaceous border with Teucrium chamaedrys, perennial sages or Santolina. It is perfect for meadows or slightly wilder areas of the garden with poppies and cornflowers. For a beautiful, flowery summer scene, combine it with Calamintha glandulosa and Nepeta 'Dawn to dusk', in open ground or in containers. In addition, it is a lovely cut flower for summer bouquets, looking like little suns in the house.

Eco-gesture :

By sowing Coreopsis in your garden, you will attract pollinating insects and other useful insects that will be lured by the smell of the nectar emanating from their flowers. In this way, you can improve the quality of your garden's ecosystem which will also help in obtaining many fruits and vegetables. So be sure to plant a few Coreopsis close to your vegetable garden.

Planting and care

Sow the Coreopsis in February-March, in a seed tray. Use good quality soil, possibly enriched with garden compost. Broadcast sow your seeds. Cover the seeds with a fine sprinkling of compost or vermiculite, tamp down lightly and water generously with a fine spray. Place your pots in a bright spot without direct sunlight, at a temperature of 20 to 25° C.

Seed emergence will take 21 to 30 days. As soon as the plants have reached a height of 10 cm, transplant them into little pots. 15 days before their planting them out in their final positions, begin to acclimatize them gradually to a temperature of 15° C.

At the end of May, beginning of June, the temperature in the garden will be warm enough to plant out your seedlings Choose a site with plenty of sunshine. Add a good shovelful of garden compost to each planting hole. Space your plants 20 cm apart.

It is possible to direct sow Coreopsis in the garden, but you will have to wait until any risk of frost has passed, around mid-May.

By removing faded flowers, you will encourage further blooming and prolong the flowering period.

Growing advice : 

Coreopsis grandiflora and its varieties do not tolerate excessive moisture in the soil in winter and heavy soil. This plant requires full sun to flower well. It likes slightly acidic, neutral or slightly calcareous, light, moist, porous, gravelly or sandy soil that is imperatively well drained. In such conditions, these plants flower and live a long time. It is best to remove faded flowers regularly, especially in July, to encourage repeat flowering until autumn. This operation will also extend the life of the plant. Rejuvenate the clumps which tend to exhaust themselves, by dividing them approximately every 3 years.
