Long-Blooming Crisp White Flowers on a Tidy Cushion

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.

Exceptionally long — from late spring into fall, especially with occasional deadheading.
Q: Will it survive a Minnesota winter?
Yes — hardy to about zone 4 with sharp drainage; plant where water doesn't pool over winter.

Yes — deer and rabbits rarely bother dianthus.
Q: Is it fragrant?

Is Constant Beauty White Dianthus Right for Your Yard?
This long-blooming pink wants full sun and sharply drained soil at the front of a border or in a rock garden, and deer and rabbits rarely touch it. Not a fit if your soil is heavy, wet clay — standing water, especially over winter, rots the crown; amend with grit or choose a raised, well-drained spot.
