Landscape Uses in Minnesota
Compact, colorful borders: The double golden pompoms shine at the front of the border and in containers. Space 14–18 inches apart.
Pollinator and low-water beds: Bees and butterflies love it; tough in hot, dry spots. Pair with coneflower, catmint, and grasses.
Best Time to Plant in Minnesota
Plant in spring (late April–May) or early fall. Provide good drainage; grandiflora coreopsis dislikes wet winter soil.
How to Plant Double the Sun Coreopsis
Dig a hole twice the pot's width at the same depth, amending heavy clay with compost or grit for drainage. Set the crown level, backfill, water in, and mulch lightly. Space 14–18 inches apart.
Watering Double the Sun Coreopsis
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. Deadhead to keep it blooming.
Q: Will it survive a Minnesota winter?
Yes, with good drainage — grandiflora coreopsis can be short-lived in wet soil, so plant it in a well-drained spot and deadhead to keep it vigorous.
Q: Do double coreopsis still feed pollinators?
Yes — bees and butterflies visit the blooms, though single types offer easier access.
Q: Is it deer-resistant?
Yes — deer and rabbits rarely bother coreopsis.
Q: How do I keep it blooming?
Deadhead regularly — it rewards you with flowers from early summer into fall.

Is Double the Sun Coreopsis Right for Your Yard?
Double the Sun thrives in full sun and sharply drained soil — it's a carefree, drought- and deer-resistant choice for the front of hot, sunny borders and containers. Not a fit if your soil stays wet, especially over winter; grandiflora coreopsis can be short-lived in soggy ground, so plant it in a well-drained spot and deadhead to keep it vigorous.
