Super Duplex Mix Dianthus offers a dazzling display of fully double, frilled blooms in a romantic blend of magenta, pink, rose, and white. Growing 12 to 24 inches tall with a well-branched, compact habit, this heirloom mix brings refined elegance to beds, containers and the cutflower garden. Bred especially for the florist trade, Super Duplex Mix is a standout in flower arrangements. Often lasting 2 weeks after cutting, the ruffled petals and intricate flower form are very similar to hydrangea blooms, giving Super Duplex Mix a premium look. As an added bonus, the sweet, clove-like fragrance is most delightful and helps to attract pollinators. Blooming from late spring through summer, these plants are beautiful but also resist deer, making them a low-maintenance and easy care option for any sunny space.
Commonly known as sweet william or garden pinks, Super Duplex Mix Dianthus is ideal for cutting gardens, cottage-style borders, patio planters, and fragrant pathways. The rich color and textured blooms complement cool-season companions like pansies, snapdragons, calendula, and lobelia. They also mix well with silver-leaved plants like dusty miller for a classic contrast. Their mid-height makes them a great fit for the front or middle of mixed plantings, and the long-lasting blooms are excellent for fresh bouquets.
Sweet William dianthus thrives in full sun and well-drained soil. Direct sow seeds after all danger of frost has passed or start indoors 6 to 8 weeks prior to last frost date. Super Duplex Mix Dianthus is a biennial, so expect blooms the second year after sowing. It prefers moderate water and benefits from regular deadheading to encourage continuous blooms. Tolerant of cool spring weather, this variety starts blooming early and maintains color deep into summer.
