Plant Data Sheet:





Galium aparine, Cleavers


Climate, elevation

Low to mid elevation

Local occurrence (where, how common)

Lowland forest and open meadows, ditches

Habitat preferences

Beaches, moist fields, clearings, ditches, open forest

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

Shade tolerant weedy colonizer; considered a noxious weed in B.C. as it climbs up agricultural crops; can be very competitive

Associated species


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


Collection restrictions or guidelines

Collect seeds in spring

Seed germination (needs dormancy breaking?)

Seed becomes dormant in dry soil

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

Seed can remain viable for 1-3 years

Recommended seed storage conditions


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

propagate by planting seeds

Soil or medium requirements (inoculum necessary?)

Prefers damp, moist soil; adapted to fine and medium textured soils

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

Seed; no known commercial source

Recommended planting density


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

High moisture usage 14-55 inches, so watering may be necessary through first dry summer



Normal rate of growth or spread; lifespan

Moderate seed spread rate; rapid growth rate; short lifespan
