Simple Campion: A Charming Native Ground Cover for Coastal Gardens

If you’re looking for a low-maintenance native ground cover that brings delicate beauty to your garden, meet simple campion (Silene scouleri var. pacifica). This unassuming perennial might not be the showiest plant on the block, but it’s got some serious charm and practicality going for it.

What Makes Simple Campion Special?

Simple campion is a true West Coast native, naturally found along the coastal regions of California, Oregon, and Washington. As a perennial forb—basically a non-woody flowering plant—it forms attractive low mats that hug the ground and produce sweet little white flowers with distinctively notched petals that look like they’ve been cut with tiny scissors.

This hardy little plant grows naturally from California’s coast up through Oregon and Washington, making it perfectly adapted to the unique challenges of Pacific coastal gardening.

Why You’ll Love Growing Simple Campion

There are several compelling reasons to consider adding this native beauty to your garden:

  • Low maintenance: Once established, simple campion is remarkably drought tolerant and requires minimal care
  • Native pollinator magnet: The small white flowers attract native bees and butterflies, supporting local ecosystems
  • Perfect ground cover: Its mat-forming habit makes it ideal for filling spaces in rock gardens or coastal landscapes
  • Coastal tough: Naturally adapted to coastal conditions, it can handle salt spray and sandy soils
  • Year-round interest: As a perennial, it provides consistent ground coverage throughout the seasons

Where Simple Campion Shines in Your Garden

This versatile native works beautifully in several garden settings:

  • Coastal gardens where it can embrace its natural habitat
  • Rock gardens where its low-growing habit complements stones and boulders
  • Native plant gardens as part of an authentic regional landscape
  • Drought-tolerant landscapes where water conservation is a priority
  • Border edges where you need a reliable, low-growing perennial

Growing Simple Campion Successfully

The best part about simple campion? It’s refreshingly easy to grow when you give it what it wants.

Growing Conditions

Simple campion thrives in USDA hardiness zones 7-10, making it suitable for most Pacific coastal regions. Here’s what it needs to flourish:

  • Light: Full sun to partial shade (though it prefers more sun)
  • Soil: Well-draining soil is absolutely essential—this plant does not like wet feet
  • Water: Drought tolerant once established; water regularly during the first growing season, then reduce watering
  • Soil type: Adapts well to sandy soils and coastal conditions

Planting and Care Tips

Getting simple campion established is straightforward:

  • Plant in spring or fall when temperatures are moderate
  • Ensure excellent drainage—consider adding sand or gravel to heavy clay soils
  • Space plants about 12-18 inches apart to allow for their spreading habit
  • Water regularly during the first year to establish roots
  • Once established, water only during extended dry periods
  • Minimal fertilization needed—this plant prefers lean conditions
  • Deadhead spent flowers to encourage continued blooming

Is Simple Campion Right for Your Garden?

Simple campion is an excellent choice for gardeners who appreciate native plants and want a reliable, low-maintenance ground cover. It’s particularly perfect if you’re gardening in coastal conditions or creating a drought-tolerant landscape.

However, it might not be the best fit if you’re looking for a bold, showy focal point or if you have heavy, poorly-draining soil that you can’t amend. This plant also may not perform well in areas with high humidity and poor air circulation.

By choosing simple campion, you’re not just adding a pretty ground cover to your garden—you’re supporting local wildlife and celebrating the natural heritage of the Pacific coast. Sometimes the most rewarding plants are the quiet, dependable ones that just get the job done beautifully, year after year.
