Montrose White Calamint
A Months-Long Cloud of Tiny Flowers That Bees Can't Resist
Montrose White Calamint (Calamintha nepeta 'Montrose White') is one of the best pollinator plants you can grow — an airy, billowing mound of minty, aromatic foliage covered in a haze of tiny white-to-pale-blush flowers from midsummer until frost. It hums with bees all season, asks for almost nothing, and its fragrant foliage keeps deer away. Tough and drought-tolerant, it's a soft, long-blooming filler for sunny borders and pathways in Edina, Woodbury, and Maple Grove.

Landscape Uses in Minnesota
Pollinator gardens: Few plants draw more bees — the months-long haze of flowers is alive with pollinators all season. Space 12–15 inches apart.
Soft border filler and edging: Its airy texture softens stiffer plants and edges pathways beautifully. Pair with coneflower, catmint, and ornamental grasses.
Best Time to Plant in Minnesota
Plant in spring (late April–May) so it establishes over the full season, or early fall in a sheltered spot. It needs good drainage to overwinter at the cool edge of its range.
How to Plant Montrose White Calamint
Dig a hole twice the pot's width at the same depth. Amend heavy clay with grit for drainage. Set the crown level, backfill, water in, and mulch lightly, keeping mulch off the crown. Space 12–15 inches apart.
Watering Montrose White Calamint
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. It dislikes soggy soil.
Q: Will it survive a Minnesota winter?
It's hardy to zone 5 and overwinters well in most Twin Cities gardens with sharp drainage. In exposed zone 4b sites, mulch the crown and avoid wet soil.
Q: Is it really that good for bees?
Yes — calamint is among the top bee plants in the perennial world, buzzing nonstop from midsummer to frost.
Q: Is it related to mint — will it spread aggressively?
It's in the mint family with aromatic foliage, but it stays as a tidy clump rather than running like true mint. It may self-sow lightly.
Q: Is it deer-resistant?
Yes — the minty, aromatic foliage is strongly disliked by deer.
