Frosty Fire Dianthus
Frosty Fire Dianthus (Dianthus 'Frosty Fire')
Frosty Fire Dianthus (Dianthus 'Frosty Fire') is a compact perennial valued for fiery red blooms held above cool silvery blue foliage and a classic clove like perfume. Flowering from late spring through summer, it forms a tight evergreen mound that delivers strong color contrast in borders, rock gardens, and containers while staying tidy in sunny, well drained sites; the vivid flowers can serve as a focal point in small spaces.
