Bumbleberry Pie Dianthus
Fragrant Berry-Purple Blooms With a Dark Eye
Bumbleberry Pie Dianthus (Dianthus 'Bumbleberry Pie') is a deliciously named charmer — berry-purple, clove-scented flowers marked with a deeper eye, over a neat cushion of blue-green foliage. Blooming heavily in late spring and reblooming through summer, it's tough, drought-tolerant, and deer-resistant, with semi-evergreen foliage. A rich, fragrant front-of-border favorite for sunny beds and rock gardens in Edina, Woodbury, and Maple Grove.

Landscape Uses in Minnesota
Fragrant edging and rock gardens: The rich berry tones and neat cushion make a vivid 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 Bumbleberry Pie 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 Bumbleberry Pie 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 Bumbleberry Pie Dianthus Right for Your Yard?
Bumbleberry Pie wants full sun and sharp drainage — front borders, rock gardens, and gritty edges where its clove fragrance can be enjoyed up close. Avoid wet, heavy clay and spots where water pools over winter, the main cause of crown rot in pinks; add grit to clay before planting.
