Rubus leucodermis

Rubus leucodermis, also known as whitebark raspberry, is a deciduous shrub that is native to western North America. The seeds can be germinated by cold stratification, which involves placing them in a moist, cool environment for a period of time before planting. To stratify the seeds, they should be placed in a plastic bag with a damp paper towel and stored in the refrigerator for 60-90 days. After stratification, the seeds can be sown in well-draining soil and kept moist until germination, which typically takes 3-4 weeks.

Some of plants may have very have specific germination requirements that may not be covered in these general instructions. 

Many seeds require pre-treatment before sowing which we try to list here when we can, but this information may not be present here.  Germination times and germination temperatures are to be a guide only.  Many factors can DRASTICALLY affect this.


It's always a good idea to research the specific germination requirements from multiple sources for each plant before attempting to grow them from seed.
