The detail
This range is known for its fully double, intricately ruffled carnation-style blooms, produced in abundance from early spring through late summer. Flowers span a rich and expressive colour palette, including soft pinks, bright rose tones, deep cherry and dark red hues, crisp whites, and striking bicolour combinations with star-shaped or contrasting centres. Each bloom forms a plush, cushion-like flower head with fine petal detail, held neatly above compact, well-branched mounds of grey-green foliage. Plants remain naturally tidy and uniform, creating polished displays whether planted individually or en masse.
All plants are supplied as large, healthy, well-established 10.5 cm rootballs, professionally grown in peat-free compost at a UK nursery in Yorkshire. Stronger and more reliable than standard plugs, they establish quickly after planting and deliver earlier, heavier flowering. Plants are dispatched in plastic-free, recyclable packaging, providing a more sustainable and garden-ready option from the moment they arrive. Available in sets of 3, 6, or a mixed tray of 15 plants.
