Coreopsis auriculata Elfin Gold

The Coreopsis auriculata f.nana Elfin Gold is a small, compact, hardy, and floriferous perennial. It offers an abundance of small, bright yellow heads throughout the summer, except during periods of intense heat, where butterflies gather. This flowering contrasts beautifully with its tough, glossy, dark green leaves. Its lifespan is relatively brief, but it spreads and regenerates thanks to a stoloniferous base. This plant is a generous and undemanding non-native ground cover that easily naturalises in a rock garden or on a slope in well-drained, moist soil and full sun.

The Coreopsis auriculata, or auriculate coreopsis, is a short-lived perennial belonging to the Aster family, like sunflowers and asters. It gets its name from a morphological characteristic of its leaves, which have lobes resembling ears at the base. This hardy plant is native to the southeastern and central-eastern United States, from eastern Louisiana to Florida, Kentucky, Maryland, and West Virginia. Its origins mean it is known for its resistance to humid heat and tolerance to drought.

The 'Elfin Gold' variety, derived from the 'Nana' form, stands out for its compact habit and reduced pruning, reaching a height of no more than 15 cm (6in). This plant blooms abundantly from early summer, but the flowering slows down in case of intense heat and prolonged drought, only to pick up again in September with the return of rain or thorough watering. It produces wide, warm and bright yellow daisy-like flowers, about 4 cm (2in) in size, carried by slender stems. The foliage is composed of glossy dark green, lanceolate leaves gathered at the base. After flowering, this plant develops short, non-trailing rooted stems that allow it to spread in large colonies, thanks to nodes that root upon contact with the ground.

Perennial coreopsis plants dislike winter humidity and heavy soils. These plants require full sun, even scorching, to flower well. They prefer light, porous, gravelly or sandy soil that is always well-drained. They are rewarding plants that require little maintenance. The Coreopsis auriculata 'Elfin Gold' is a small perennial with multiple uses. It will thrive in a rock garden, on a slope with wallflowers, Damask nigellas, and wild flax, or in an herbaceous border alongside Teucrium chamaedrys or x lucidrys, thyme, santolines, or poppies. For a beautiful, water-efficient summer display, whether in the ground or a large pot, it can be paired with Calamintha glandulosa and Nepeta 'Dawn to dusk'. This ground cover elegantly borders pathways while limiting weed growth reducing maintenance.
