Pink Frost Dianthus
Fragrant Pink Blooms Over Frosty Silver-Blue Foliage
Pink Frost Dianthus (Dianthus 'Pink Frost') tops a tidy cushion of frosty, silver-blue foliage with clove-scented soft pink flowers. Blooming heavily in late spring and reblooming through summer, it's tough, drought-tolerant, and deer-resistant, with semi-evergreen foliage that adds cool color even in winter. A fragrant, easy-care favorite for sunny edges and rock gardens in Edina, Woodbury, and Maple Grove.

Landscape Uses in Minnesota
Fragrant edging and rock gardens: The frosty silver mound makes a striking front-of-border edge and thrives in well-drained rock gardens. Space 10–12 inches apart.
Pollinator and deer-resistant beds: Butterflies visit the fragrant blooms, and deer leave it alone. Pair with catmint, salvia, and sedum.
Best Time to Plant in Minnesota
Plant in spring (late April–May) or early fall. Sharp drainage is essential — avoid wet, heavy soil, especially over winter.
How to Plant Pink Frost Dianthus
Dig a hole twice the pot's width at the same depth. Amend heavy clay with grit or coarse sand. Set the crown at or slightly above soil level, backfill, water in, and mulch lightly with grit or fine bark — keep mulch off the crown to prevent rot. Space 10–12 inches apart.
Watering Pink Frost Dianthus
First year: Water every 2–3 days at first, then weekly. Stop 2–3 weeks before the ground freezes.
After year one: Drought-tolerant — water only during extended dry spells. Overwatering and wet soil are its main enemies.
Q: Will it survive a Minnesota winter?
Yes — hardy to about zone 4 with sharp drainage; plant where water doesn't pool over winter.
Q: Is it fragrant?
Yes — the flowers carry the classic sweet, spicy clove scent of pinks.
Q: How do I keep it blooming?
Shear off spent flowers after the first flush to encourage rebloom through summer.
Q: Is it deer-resistant?
Yes — deer and rabbits rarely bother dianthus.

Is Pink Frost Dianthus Right for Your Yard?
It thrives in full sun and lean, sharp-draining or gritty soil, where its silver foliage and fragrant blooms shine and deer leave it alone — ideal for sunny edges, rock gardens, and border fronts. It is not a fit if your soil stays wet and heavy, especially over winter, when the crown is prone to rot; amend clay with grit or choose a raised, well-drained spot.
