Plant Data Sheet
Cloudberry - Rubus chamaemorus
Circumboreal species, from
Lower elevations, bogs.
Local occurrence (where, how common)
Common in sphagnum bogs.
Clouberry grows in a wide variety of sites from wet to dry but dominates or co-dominates in peat bogs.
Plant strategy type/successional stage
Faculative Seral Species
“Cloudberry is shade tolerant. In the bog flats of southwestern
, it was one of the first species to come in after dense sphagnum cover was established. Cloudberry is an important component in the understory of mid- to late-seral northern woodlands.” (FEIS database) Fire is also common in the shrub-tussock tundra, Clouberry resprouts after fire from rhizomes. Alaska
Picea mariana/ sphagnum bog, Betula Nana, Betula glandulosa, Ledum goenlandicum, Calidonia spp.,
May be collected as: (seed, layered, divisions, etc.)
Cloudberry reproduces primarily by rhizomes.
Collection restrictions or guidelines
Recommended to not collect rhizomes since bogs are fragile, berries only.
Seed germination (needs dormancy breaking?)
Seed life (can be stored, short shelf-life, long shelf-life)
Recommended seed storage conditions
Remove flesh, store in cool dry place.
Propagation recommendations (plant seeds, vegetative parts, cuttings, etc.)
Most successful proagation will be from one wild-collected plant, produce rhizomitously. Can be propagated by seed.
Soil or medium requirements (inoculum necessary?)
Will grow best in Sphagnum.
Installation form (form, potential for successful outcomes, cost)
Recommended planting density
Care requirements after installed (water weekly, water once etc.)
Saturated soil, sphagnum wetbed perhaps.
