Neon Star Improved Dianthus
Electric Magenta-Pink Blooms on a Tidy Cushion
Neon Star Improved Dianthus (Dianthus 'Neon Star Improved') blazes with electric magenta-pink, clove-scented flowers over a dense cushion of blue-green foliage. An improved selection of a garden favorite, it blooms heavily in late spring and reblooms through summer. Tough, drought-tolerant, and deer-resistant with semi-evergreen foliage, it's a knockout, fragrant front-of-border choice for sunny beds and rock gardens in Edina, Woodbury, and Maple Grove.

Landscape Uses in Minnesota
Fragrant edging and rock gardens: The vivid color and neat cushion make a standout front-of-border edge. 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 Neon Star Improved 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 Neon Star Improved 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.

How Many Neon Star Improved Dianthus Do I Need?
Neon Star forms a tidy 10–12 inch cushion, so space plants about 11 inches apart for a solid front-of-border ribbon:
| Bed run | Plants needed (11 in. spacing) |
|---|---|
| 5 ft | 5 |
| 10 ft | 11 |
| 15 ft | 16 |
| 20 ft | 22 |
For rock gardens and edges, plant in clusters of 3–5 about 10–11 inches apart so the cushions merge into a fragrant mat.

Is Neon Star Improved Dianthus Right for Your Yard?
Neon Star thrives in full sun with sharply drained soil — it's perfect for edges, rock gardens, and dry sunny beds, and deer and rabbits rarely bother it. It is not a fit for wet, heavy clay: standing winter moisture rots the crown, so add grit and keep mulch off the crown.
