Pre-treatment: Mix an equal amount of seeds with either perlite or vermiculite in a Ziploc-style bag or a small Rubbermaid-style container. Add a small amount of water (no visible water should be in the bag or container). Place in a refrigerator or garage (33-42 degrees F) for at least 3 months. Seeds can be cold stored until planted (up to 3 years). Alternatively, seeds can be warm and cold stratified for 60 to 90 days.
Establishment: Seed is collected from locally native plants within the eastern central Upper Peninsula. Fruit is red and the size of a cranberry. The plant is native to swamps (both hardwood and conifers), borders of woods and shores, wet roadsides, ditches, banks and thickets along rivers and streams, fens. It is a woody multi-stemmed shrub. V. opulus is also native to temperate deciduous forests of North America and Europe.
