Long-Blooming Crisp White Flowers on a Tidy Cushion
Constant Beauty White Dianthus (Dianthus 'Constant Beauty White') brings clean, clove-scented white flowers over a compact cushion of blue-green foliage, from late spring well into fall. Bred for an exceptionally long bloom season, it's tough, drought-tolerant, and deer-resistant, with semi-evergreen foliage. Crisp white blends with any scheme — a versatile, fragrant front-of-border favorite for sunny beds and rock gardens in Edina, Woodbury, and Maple Grove.

Landscape Uses in Minnesota
Versatile long-season edging: White blends with everything and its extended bloom makes it a front-of-border workhorse. 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 Constant Beauty White 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 — keep mulch off the crown to prevent rot. Space 10–12 inches apart.
Watering Constant Beauty White 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 — deer and rabbits rarely bother dianthus.
Q: Is it fragrant?
