Germination Information
Pre-treatment: Seeds are stratified naturally by planting them in the fall in a thin layer of sand on mulched field beds. Stratification lasts 1 to 2 months. Wet tumbling is beneficial, which involves putting the seeds in a rubber-lined rock tumbler jar with tap water. The water is changed daily to remove any inhibitors that may have leached out.
Establishment: Seeds are collected during fall months and are kept separated according to site, elevation and source. The seeds must be transplanted soon after germination before radicle elongates. Some species may benefit from a rigorous imbibition treatment and/or leaching of germination inhibitors.
