Coreopsis Redshift

The Coreopsis 'Redshift' is a new variety of coreopsis with beautiful vigour that seduces with its multicoloured and changing flowering depending on the temperature and season. From summer to the first frost, its generally bicolour blooms flower one after another, dominated by yellow tones in summer, but much more red in autumn. Each gradually transitions from pale yellow to red and then to plum on this plant that forms a beautiful bushy shrub adorned with light foliage of a vibrant green. This excellent variety is resistant to cold and diseases. Plant it in well-exposed borders, in not too dry rockeries, in natural areas of the garden or in a pot on the patio.

Coreopsis belongs to the Asteraceae family. 'Redshift' is part of a series of hybrids recently developed in the United States by Darrel Probst, a specialist in the genus. The series, called 'Big Bang', brings together varieties like 'Mercury Rising', 'Cosmic Evolution' and 'Galaxy', initially selected for their cold resistance, vibrant colours, and vigour. All these qualities are present in 'Redshift'.  This rhizomatous perennial quickly forms a bushy and upright shrub, reaching an average height of 50 cm (20in) and a width of 40 cm (16in). Flowering takes place from late June to October, almost without interruption. The 4 cm (2in) diameter flower heads open in a very pale yellow tone, then gradually and randomly tint in shades of pink, red, purple, and wine, around a small amber-yellow centre. When the temperature drops, at the end of the season, the flowers are almost completely red. They are carried at the top of short upright stems. This plant develops opposite, lanceolate, finely divided leaves measuring 4 to 7 cm (2 to 3in) in length and of a vibrant green colour, with a very airy appearance.

The Coreopsis 'Redshift' is a hardy and robust perennial with multiple uses. Plant it in a rockery, on a countryside slope with wallflowers, damask flowers, echinaceas, goldenrods, and wild flax, in an herbaceous border in the company of Teucrium chamaedrys or x lucidrys, cosmos, and annual cornflowers. In a pot or container, this plant blooms continuously from the first year. For beautiful summer blooms, it can be paired with Stipa tenuifolia, Calamintha glandulosa, and Nepeta 'Dawn to dusk' in the ground or in a large pot, with a little water. It is also a lovely flower for summer bouquets.
