Moonbeam Coreopsis
The Award-Winning Soft-Yellow Classic
Moonbeam Coreopsis (Coreopsis verticillata 'Moonbeam') is a former Perennial Plant of the Year and a garden staple for good reason — a soft, airy mound of ferny threadleaf foliage covered in gentle, creamy pale-yellow daisies from early summer into fall. Its muted color blends beautifully with everything, and it's as tough as it is pretty: drought-tolerant, deer-resistant, and a pollinator favorite. A timeless choice for sunny borders in Edina, Woodbury, and Maple Grove.

Landscape Uses in Minnesota
Soft-toned sunny borders: The gentle yellow knits beautifully between bolder perennials and softens hot color schemes. Space 18–24 inches apart.
Pollinator and prairie gardens: Bees and butterflies love it; it spreads gently to fill space. Pair with coneflower, catmint, and salvia.
Best Time to Plant in Minnesota
Plant in spring (late April–May) or early fall. It's adaptable but appreciates good drainage.
How to Plant Moonbeam Coreopsis
Dig a hole twice the pot's width at the same depth, loosening clay and mixing in compost. Set the crown level, backfill, water in, and mulch lightly. Space 18–24 inches apart.
Watering Moonbeam 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. A midsummer shear refreshes it for fall bloom.
Q: Why is Moonbeam so popular?
Its soft, creamy yellow blends with any color, it blooms for months, and it's tough and low-maintenance — earning it Perennial Plant of the Year honors.
Q: Will it survive a Minnesota winter?
Easily — hardy to zone 3, returning faithfully each year.
Q: Is it deer-resistant?
Yes — deer and rabbits rarely bother coreopsis.
Q: Does it spread?
It spreads gently by rhizomes to form a soft colony — easy to manage.

How Many Moonbeam Coreopsis Do I Need?
Moonbeam spreads gently to 18–24 inches, so space plants about 20 inches apart for a soft, knit-together drift:
| Bed run | Plants needed (20 in. spacing) |
|---|---|
| 5 ft | 3 |
| 10 ft | 6 |
| 15 ft | 9 |
| 20 ft | 12 |
For borders, plant in groups of 3–5 about 18–20 inches apart; the soft yellow knits beautifully between bolder perennials.

Is Moonbeam Coreopsis Right for Your Yard?
Moonbeam thrives in full sun with average-to-lean, well-drained soil — it's drought-tolerant, deer-resistant, and blooms for months once established. It is not a fit for shade or soggy ground: too little sun thins the bloom and wet winter soil can rot the crown.
