Ozark calamint

Year-round

Ozark calamint is a small perennial mint-family wildflower native to limestone cedar glades and creekside seeps in a narrow range outside this region (the Nashville Basin, Kentucky's Bluegrass Region, and northern Alabama), with pale pink tubular flowers in late spring.

• It is naturally adapted to thin, mineral soil over exposed limestone that stays consistently damp from seeps, which is harder to replicate in a typical yard.
• Give it full sun to light shade and a spot that does not dry out completely between waterings.
• It is a vulnerable species with a very narrow native range, so treat it as a specialty planting rather than a general-purpose groundcover.
• Keep it out of standing water; the habitat is consistently moist, not waterlogged.

Grown low and mounding in a defined bed or rock garden, it reads as a tidy, intentional groundcover.

Fall

Growth slows as temperatures cool; fall is a reasonable time to establish new plantings before winter.

• Keep new plantings watered through fall until they are established.
• Clear fallen leaves off the low mound so it isn't smothered.
• No pruning is needed beyond removing spent growth.

Winter

The plant goes dormant over winter in its native cool-season glade habitat.

• Keep the site from drying out completely even in dormancy; it is not adapted to prolonged winter drought.
• No mulch beyond what naturally falls is typically needed.
• Avoid disturbing the crown until new growth resumes in spring.

Spring

Spring brings new growth and the late-spring bloom of small pink tubular flowers.

• Keep soil consistently moist as new growth emerges; this species does not tolerate drying out.
• No feeding is needed; it grows naturally in thin, mineral soil rather than rich garden beds.
• Watch for flowering to begin in May as temperatures warm.

Summer

Summer heat is the main risk period; the plant needs steady moisture even as temperatures climb.

• Water during dry spells rather than letting the soil dry out completely, mimicking its natural seep habitat.
• Light afternoon shade can help it through the hottest stretch of summer if grown outside a naturally cool glade setting.
• Trim lightly after bloom fades to keep the mound tidy.
