Plant Data Sheet




Species (common name, Latin name)Piperís bellflower, Campanula piperi



Campanula piperi is dwarf alpine species endemic to the Olympic Mountains in western Washington.


Climate, elevation

Found in high elevations on drier slopes


Local occurrence (where, how common)

Found only in the Olympic Mountains in Western Washington


Habitat preferences

C. piperi prefers drier slopes and is found in rock crevices


Plant strategy type/successional stage (stress-tolerator, competitor, weedy/colonizer, seral, late successional)



Associated species



May be collected as: (seed, layered, divisions, etc.)

C. piperi can be propagated from seeds or divisions.


Collection restrictions or guidelines

If collecting seeds or plants in national parks or forest, please refer to their guidelines for gathering and removing plant materials.


Seed germination (needs dormancy breaking?)

Plant seeds directly in the fall or start stratified seeds inside. If started inside, should be sowed when soil reaches 68ļF. Germination is slow. Do not cover seeds.


Seed life (can be stored, short shelf-life, long shelf-life)



Recommended seed storage conditions



Propagation recommendations (plant seeds, vegetative parts, cuttings, etc.)

Increase by division early in spring by root cuttings or by stem cuttings taken with a bit of rootstock at the base of the shoot.


Soil or medium requirements (inoculum necessary?)

Open, quick-draining, but moisture retentive soils of moderate fertility and a neutral Ph will work fine for most mountain plants that can be found in drier mountain slopes.


Installation form (form, potential for successful outcomes, cost)



Recommended planting density

Prefers to be planted in small crevices


Care requirements after installed (water weekly, water once etc.)

Water normally


Normal rate of growth or spread; lifespan

Divide every 3 to 4 years
