Dianthus Cosmopolitan

Few plants deliver such charming colour in such a neat, compact package as Dianthus ‘Cosmopolitan’, making it a standout choice for brightening patios, borders, and containers. This dazzling perennial produces rich pink blooms marked with a rich crimson eye, each finely fringed flower adding striking detail and charm. The blooms appear in abundance from late spring and continue well into summer, often rewarding regular deadheading with repeat flushes. Held above tidy mounds of slender blue-green foliage, the flowers create a lively, long-lasting display that instantly lifts sunny spaces.
Compact and easy to grow, Dianthus ‘Cosmopolitan’ thrives in full sun and any well-drained soil, making it perfect for edging pathways, planting in rockeries, or adding punch to mixed containers. Hardy and low maintenance, this dianthus is ideal for gardeners seeking reliable colour, crisp form, and weeks of summer brilliance with minimal effort.
Supplied as a large bushy plant in approx. 1-2 litre containers.
