Coreopsis grandiflora Mayfield Giant seeds

Coreopsis grandiflora 'Mayfield Giant' is a perennial plant belonging to the group of Coreopsis grandiflora which gathers medium to tall varieties (45 to 90 cm). This variety produces large sun-yellow flowers with fringed petals, carried by thin, erect, leafless stems almost continuously from June to October, ideal for cutting. Requiring little maintenance, it brightens up flower beds and borders, or pots on the terrace or balcony.

Coreopsis grandiflora belongs to the Asteraceae family. It originates from North America, from California, and from New Mexico to the Great Lakes. 'Mayfield Giant' is a rhizomatous perennial plant that forms a basal, rounded clump, 70 to 80 cm tall when in flower and 40 to 50 cm wide. Flowering occurs from June to October. The 7.5 cm diameter, solitary heads are borne on slightly hairy stems. The beautiful intense green foliage is deciduous. The opposite, lanceolate, entire leaves, sometimes incised at the base, almost sessile (without petiole), measure 10 cm long. This perennial spreads quite rapidly through rhizomes.

The 'Mayfield Giant' coreopsis dislikes winter moisture and heavy soils. This plant requires full sun to flower well. It likes light and moist soil, always well-drained, slightly acidic, neutral or slightly calcareous. In such conditions, these plants flower and live long. To promote reblooming, regularly remove faded flowers. This operation will also extend the plant's lifespan.

Coreopsis grandiflora 'Mayfield Giant' is a versatile perennial, ideal both in a rockery, on a slope alongside wallflowers, love-in-a-mist and wild flax, and in a herbaceous border with Teucrium chamaedrys, thyme and cotton lavenders. Perfect for greening a slightly wild area, this plant also adapts very well to cultivation in pots or containers, offering continuous flowering from the first year. In the ground or in a large pot, it requires little water and pairs wonderfully with Calamintha and Nepeta 'Dawn to dusk' for a flowery summer. Its bright flowers add a vibrant touch to summer bouquets.
